RT
flat chip resistors (anti-sulfuration)
features
• Excellent anti-sulfuration characteristic
EU
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
