Product Introduction

Product features

■ Double-sided vapour plating structure, able to withstand high voltage and over-current capability

■ Withstand high frequency pulse currents

■ Low self-inductance and low temperature rise

■ Dry construction, solid epoxy encapsulation

■ Electronic insulating tape wrapping (optional mounting bracket for simplicity and convenience)

■ Low equivalent series resistance

Note .

Please contact us for other electrical capacities, dimensions and performance parameters.

Typical applications

■ Widely used in IGBT buffer absorption lines, e.g. spike voltage and spike current absorption protection during spikes when switching power supplies are switched off.
