Würth Elektronik eiSos WE-CPIB HV high-voltage double chokes

Würth Elektronik eiSos presents the WE-TDC HV double choke optimised for SMT assembly. The magnetically shielded 1:1 transformers with an isolation voltage of 2000 V offer low losses and a low level of stray inductance. The product family encompasses nine different models — five in an 8038 package and four in 8018. The height of the chokes is 1.8 mm and the components are packaged in 16 mm tapes.

The chokes are specified for the extended operating temperature from -40 to +125°C and have a functional isolation for a working voltage of 250 V_RMS. They are suitable for use in switching controllers with a second, unregulated output voltage; in buck, boost, Sepic, Zeta and CUK converters; as well as in isolated converter applications with high packaging density (eg, flyback converters).
