High-voltage double chokes

27 March 2019 Passive Components

With its WE-TDC HV, Würth Elektronik eiSos has introduced a further double choke optimised for SMT assembly.

The magnetically shielded 1:1 transformer, with an isolation voltage of 2 000 V, boasts very lower losses and a low level of stray inductance.

The product family encompasses nine different models – five in an 8038 package and four in an 8018 – each with a height of just 1,8 mm. The chokes are specified across extended operating temperatures from -40°C to +125°C, and have functional isolation for a working voltage of 250 VRMS.

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 (e.g. flyback converters).

The components are packaged in 16 mm tapes, are available from stock, and samples can be requested.
