High-voltage double chokes

14 November 2018 Passive Components

Würth Elektronik eiSos has added the smallest double choke of its type to its portfolio. Featuring a 2 kV isolation voltage in a 4828 package, the WE-CPIB HV 1:1 transformer is magnetically shielded and offers functional isolation for a working voltage of 250 V_RMS.

The component is optimised for SMT manufacturing and is specified for the temperature range from 40°C 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. WE-CPIB HV can be used as an individual inductor with series and parallel connection.

The part is now available from stock in any quantities, in versions with inductance values between 4,7 and 47 μH. Free samples can be requested.
