RK73-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
• 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)
