RK73-RT

resistors

flat chip resistors (anti-sulfuration)

features

•

Excellent anti-sulfuration characteristic

due to using high sulfuration-proof inner

top electrode material

•

Excellent heat resistance and weather

resistance are ensured by the use of metal glaze thick film

•

High stability and high reliability with the triple-layer

structure of electrode

•

Suitable for both flow and reflow solderings

•

Marking: Black protective coat on RK73B, RK73Z1J, 2A,

2B, 2E, W2H, W3A

Blue protective coat on RK73H

Green protective coat on RK73Z1E

•

Products with lead-free terminations meet EU RoHS

requirements. Pb located in glass material, electrode

and resistor element is exempt per Annex 1, exemption

5 of EU directive 2005/95/EC
