TDK Corporation (TSE: 6762) introduces the new PCM120T series of shielded SMT power inductors, optimized for high saturation currents and low DC resistances. The PCM120T product family includes 14 inductance values between 0.4 μH and 10 μH, whereby saturation currents of up to 80 A are reached depending on the L value. Optimal saturation properties are achieved through the use of an iron alloy core. Flat wire windings are used to keep losses as low as possible. This results in low ohmic resistance values (RDC) of 0.72 mΩ (0.4 μH) to 9 mΩ (10 μH). The new inductors have an outstanding EMC performance due to closed housing made of ferrite material without an external gap. They are ideal for automatic solder joint inspection (AOI) and achieve a coplanarity of <0.1 mm due to their lead frame structure. The product’s metal cores provide resistance against high voltage pulses in accordance with ISO7636. The components’ dimensions are 12.7 x 15.8 x 11.5 mm (W x L x H). The powerful RoHS-compatible inductors are designed for a wide temperature range from -55 °C to +165 °C and are certified according to AEC-Q200.

TDK Corporation (TSE:6762) presents the new B78416A* series of compact EPCOS transformers with EP 6 cores for ultrasonic applications. The series comprises five types with transformation ratios between 1:1:8.42 and 1:1:15. Depending on the type, the new SMD-version transformers offer inductance values between 3 mH and 5 mH and are suitable for frequencies between 52 kHz and 300 kHz. The components are compliant with AEC-Q200, feature highly compact dimensions of just 9.0 x 7.6 x 7.1 mm and are magnetically shielded for better interference suppression. The permissible temperature range lies between -40 °C and +125 °C.

This guide introduces CNA series – low-resistance soft termination products, which achieves both high reliability and low resistance.

TDK Corporation (TSE: 6762) has extended its range of bipolar DC high-voltage contactors to include the new HVC43 (B88269X3**0C011) series. These products complete the existing range by offering continuous currents from 150 A DC to 250 A DC and operating voltages of up to 1000 V DC. The contactors are available in 12 V or 24 V coils with a power consumption of 6 W.

TDK Corporation (TSE: 6762) presents with the B40640B* and B40740B* series hybrid polymer capacitors with a very high ripple current capability increased by up to 29 per cent compared to preceding types. The ripple current capability is now up to 35 A (20 kHz, 125 °C). The new types are designed for a rated voltage of 63 V, cover a capacitance range from 390 µF to 720 µF, and offer an extremely low ESR value. For example, with a cup size of 16 mm x 30 mm (D x H) and an ambient temperature of 20 °C, an ESR of 3.9 mΩ at 20 kHz can be achieved. Even at an operating temperature of -40 °C, the ESR is just 5.4 mΩ.

Current electronic control units (ECUs) in automobiles use mainly differential signal communications with twisted-pair wires to simplify and reduce the weight of vehicle wiring harnesses.
Among these, the CAN (Controller Area Network) communication system is used for communications that require extremely high reliability such as driving, turning, and stopping.

TDK Corporation (TSE: 6762) presents the EPCOS E10 EM series, a new range of insulated SMT transformers that are suitable for various DC/DC converter topologies and gate driver circuits in e-mobility and industrial electronics. There are four models in the series, with basic winding insulation of a working voltage of 500 VRMS and reinforced insulation of 300 VRMS. The turns ratio is between 1:0.76 and 4:1, depending on the model.

TDK Corporation (TSE: 6762) has extended its portfolio of EPCOS ERU SMT power inductors with the ERU16 choke series, comprised of ten different types. The inductance values of the new B82559B*A016 series, which replaces the former B82559A*A016 series, extend from 1.0 µH to 30 µH, and their saturation currents range from 10.3 A DC to 40.4 A DC at 25 °C.

TDK Corporation (TSE: 6762) presents two new series of ThermoFuse® varistors, which are equipped with monitor outputs and integrated thermal protective components for overvoltage protection.
The MT25 series (B72225M*) currently covers a voltage range from 150 VRMS to 385 VRMS, and its maximum surge current capability is 20 kA at a pulse form of 8/20 µs, according to IEC 61643-11. With dimensions of 25 x 28 x 14 mm, the completely encapsulated protective components feature a particularly compact design. Their monitor outputs are optionally available with or without electrical isolation.

TDK Corporation presents a new range of Open Mode chip varistors for electronic automotive assemblies that are directly connected to the battery. The new chip varistors offer reliable protection against transient surge voltages according to ISO 7637-2, and meet the failsafe requirements according to the VW standard VW 80808. Even when subject to excessive bending stress, short-circuits are avoided, which is particularly important for unswitched battery terminals (e.g. terminal 30).
