05小图.jpg

Product features

■ Low self-inductance, small size and low temperature rise

■ Dry construction, solid epoxy encapsulation

■ Square plastic case construction with tinned copper lead-in (easy installation)

■ Small 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.
