Wurth Electronics PD HV Standard Shielded SMD inductor

Wurth Electronics PD HV Standard Shielded SMD inductor

Wurth Electronics PD HV Standard Shielded SMD Inductor is the market's first SMD inductor which is tested and rated up to 400V DC. The WE-PD HV is available in three sizes of 7x7mm, 10x10mm and 12x12mm. With a wide range of inductance values within the sizes there is a fit for nearly all circuits (220µ - 3300µH. The PD HV is a cost effective and small solution as an input filter in AC/DC switch mode power supplies. This series is extremely useful in the LED lighting market for un-isolated step-down designs like in LED light bulbs for example. In addition Wurth Electronics already offers 400V high voltage inductors as unshielded SMD and THT configurations.

Comments from Wurth Electronics
  • The ambient temperature when operating the WE-PD series of storage chokes at full current rating load should generally range from –40 °C to +85 °C.
  • The self-heating of the component must be taken into account at higher ambient temperatures in order that the permissible solder joint temperature is not exceeded or the wire insulation damaged. The wire used can withstand a temperature of up to +180 °C.
  • The ferrite core itself may be used over a far greater temperature range (approx. –50 °C to +250 °C temperature). However, in this case, the tolerance limits of the inductor may be exceeded due to the temperature dependence of permeability.
