Würth Elektronik WE-CPIB HV double chokes

The WE-CPIB HV double chokes, featuring 2 kV isolation voltage, come in a 4828 package, making them the smallest of their type in the Würth Elektronik portfolio. The 1:1 transformer is magnetically shielded and offers functional isolation for a working voltage of 250 V_RMS.

The double choke offers better leakage inductance (LS) and resistance (RDC) values than comparable components on the market, according to the company. The component optimised for SMT manufacture is specified for the temperature range from -40 to +125°C.

Typical applications include isolated converter applications (such as flyback converters) with high packaging density buck, boost, Sepic, Zeta and CUK converters, as well as switching controllers with a second, unregulated output voltage. The product can be used as an individual inductor with series and parallel connection. It is available in versions with inductance values between 4.7 and 47 µH.
