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.

• AEC-Q200 Qualified: 0402 (1E), 0603 (1J), 0805 (2A),

1206 (2B), 1210 (2E), 2010 (W2H), 2512 (W3A)
