電流検出抵抗器

Current sense resistors are recognized as cost-effective components that help improve system efficiency and reduce losses due to their high measurement accuracy compared to other technologies.

While they are ideal for applications in virtually all market segments, current sense resistors are particularly useful in helping developers precisely measure current in their consumer and industrial designs.

Bourns offers current sense chip resistors with thick film, metal foil and metal strip resistive elements and electro-beam welded metal strip shunts.
