CeraLink in modular flex-assembly technology
The lineup of proven CeraLink™ capacitors has been extended with CeraLink FA types in modular flex-assembly technology. This space-saving design connects two, three or ten identical capacitors in parallel over the same terminals in order to increase the capacitance.
The new CeraLink FA types are available for rated voltages of 500 V DC, 700 V DC and 900 V DC. Depending on the voltage and number of capacitors, this results in nominal capacitance values of 0.5 µF to 10 µF.
One particular feature of these capacitors based on PLZT (lead lanthanum zirconate titanate) ceramics is their high permissible operating temperature of 150 °C. The FA types have a width of 7.4 mm and a height of 9.1 mm; while the lengths are 6.3 mm, 9.3 mm or 30.3 mm. Despite their compact size, they feature a ripple current capability of up to 47 ARMS. One major advantage of the parallel connection is the extremely low ESR values that are significantly below 10 mΩ at high frequencies in the range of 0.1 MHz to 1 MHz.
High-current noise suppression filters for audio lines
The expanded MAF1005G series of noise suppression filters for audio lines now includes four new MAF1005GAD-D types, which, thanks to their low DC resistance, feature a high rated current of up to 1.25 A. The new types employ TDK's proprietary low-distortion ferrite that enables the new components to suppress noise at cellular frequencies from 600 MHz to 2.7 GHz and ensure high audio quality. Thanks to their high rated current, the new components are suitable especially for the audio lines for external speakers of smartphones and other compact communication devices as well as for headphones and microphones. Available in case size IEC 1005, the new noise suppression filters have miniaturized dimensions of just 1.0 mm x 0.5 mm x 0.5 mm and feature a performance approaching that of the much larger MAF1608G series in IEC 1608.
Versatile ultrasonic disks
A new series of ceramic-based ultrasonic sensor disks, comprising four standard types, have diameters ranging from 4 mm to 12 mm and thicknesses of between 0.2 mm and 4 mm. Depending on their geometry, the sensor disks permit frequencies of 200 kHz to 400 kHz or 500 kHz to 4000 kHz. The axes of oscillation are oriented either radially or axially. The RoHS-compatible sensor disks are suitable for a variety of applications. In automotive electronics, for example, they can be used in park assist or blind spot monitoring systems, level sensing for fuel or SCR tanks, as well as interior monitoring for anti-theft systems. In industrial electronics applications the sensor disks permit the flow metering of fluids or gases, and the level sensing of fluids or bulk materials. The sensor disks are also suitable for collision avoidance systems in automated forklift trucks.
Stacked MEGACAP Type MLCCs with high capacitance and low ESR
A new series of vertically stacked MEGACAP Type MLCCs that combine high capacitance and low ESR offers rated voltages from 25 V to 1000 V and covers a capacitance range from 20 nF to 150 µF. The new MLCCs are available with C0G, X7T, X7S, and X7R temperature characteristics. Thanks to their high capacitance values, the new capacitors are suitable for the resonant circuits of wireless and plug-in charging systems, for example, for industrial vehicles and robots. They can also be used in smoothing and decoupling applications in industrial equipment. The MEGACAP Type MLCCs feature metal lead frames attached to the electrode ends of the components to protect against board flexure cracks and solder cracks from thermal shocks. The metal material of the terminal has also been optimized to lower the ESR and achieve a higher ripple current capability.
Current-compensated ring core chokes for 800 V DC
The RoHS-compatible B82724J8*N040 series of EPCOS current-compensated ring core power line double chokes features a high rated voltage of 800 V DC or 250 V AC in continuous operation. The new series was developed specifically for use as DC link chokes in frequency converters. A further advantage of the new series is its outstanding thermal behavior in comparison with conventional types, which means that chokes with high inductance values can be operated with high currents, even at a high operating temperature.
The new chokes offer a range of inductance values extending from 0.5 mH to 47 mH and rated currents of between 1.6 A and 10 A, depending on the inductance. Their rated ambient temperature without derating is +70 °C. For the additional attenuation of symmetrical interferences the power line chokes feature a stray inductance of around 0.5 percent of the rated value. The dimensions for all types are 18.5 mm x 31.3 mm x 33.2 mm, just like the standard B82724J* series. This means that the new chokes can be designed into existing layouts.
SMD pulse transformers for Gigabit Ethernet and PoE
The ALT4532 series of pulse transformers has been expanded with new types for Gigabit Ethernet and Power over Ethernet (PoE) applications. The new ALT4532P type is designed for emerging 2.5GBASE-T (2.5 Gbit/s) and 5GBASE-T (5 Gbit/s) LAN applications as well as 1000BASE-T (1 Gbit/s) applications with 600-mA PoE. The new ALT4532H type is compatible with the 10GBASE-T standard (10 Gbit/s). The components feature a compact SMD package with dimensions of 4.5 mm x 3.2 mm x 2.9 mm. Mass production of the new pulse transformers was launched in February 2018.
With the new ALT4532 components TDK is responding to the rising demand for compact pulse transformers for these high-speed LAN interfaces, in particular, for the growing number of IoT devices. Thanks to their compact IEC 4532 packages, these SMD components are suitable for circuit board layouts with many pulse transformers.
Compact single-ended series with high current capability
A new series of single-ended aluminum electrolytic capacitors has been developed that feature a particularly compact design, a high CV product and high ripple current capability. The capacitors of the B41897* series are available for rated voltages of between 25 V DC and 75 V DC and cover a capacitance range from 270 nF to 12,000 nF. The dimensions of the new components range from 12.5 mm x 20 mm to 18 mm x 40 mm (d x l) depending on the voltage and capacitance. Thanks to the use of improved materials, the new capacitors can be exposed to high temperatures and are designed for continuous operation at up to 135 °C and for a peak temperature of 150 °C.
In comparison with previous series, it has been possible to increase the ripple current capability while at the same time raising the capacitance by as much as 60 percent. This means that the maximum ripple current capability is now higher than 7 A at 125 °C and 100 kHz. Typical applications include automotive ECUs and power supplies.
NTC sensor elements for temperature measurement up to 650 °C
The EPCOS NTC sensor element designed for measuring temperatures up to 650 °C is based on a high-temperature ceramic sensor element that is connected to a metallized aluminum oxide rod and then glass-encapsulated. The sensor element offers high-precision measurement with a temperature tolerance of about ±1 K at 200 °C. The component obtains its particular ruggedness from the glass encapsulation. The sensor is available optionally with wires welded to the aluminum-oxide rod. The component is 16 mm long and the glass encapsulation has a diameter of 2 mm.
The high-temperature sensor is qualified to AEC-Q200 and designed for use in especially demanding automotive electronics applications, for example, in exhaust gas recirculation systems. These are used mainly on diesel engines to reduce excess oxygen in the combustion gas and thereby minimize the formation of nitrogen oxides at high combustion temperatures. In the recirculation systems the NTC sensors measure the temperature of the exhaust gas and thus help to protect the engine against overheating – in particular, the cylinder head and valve seats.
In e-mobility applications the new sensors are able to monitor the temperature of fuel cells that are used in electric vehicle drive systems for the direct generation of electrical energy from hydrogen. Applications can also be found in household appliances, for example in self-cleaning ovens that operate on the pyrolytic principle. These work by heating the oven interior to a temperature of about 500 °C which breaks down the long-chain molecules of the food residues and reduces them largely to gas and ash. The necessary temperature is regulated and stabilized by the NTC sensors.
