RK73-RT
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
•
Marking: Z1E: Green protective coating
RK73B1E ~ W3A, RK73Z1J ~ W3A: Black
protective coating
RK73H1E ~ W3A: Blue protective coating
•
Products with lead-free terminations meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
