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.
