RK73-RT Datasheet, PDF (1/3 Pages) KOA Speer Electronics, Inc. – flat chip resistors (anti-sulfuration)

RK73-RT
flat chip resistors (anti-sulfuration)
dimensions and
construction
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: Z1H: Green protective coating
RK73B1F ~ W3A, RK73Z1J ~ W3A: Black
protective coating
RK73H1F ~ 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: 0201 (1H), 0402 (1E), 0603 (1J),
0805 (2A), 1206 (2B), 1210 (2E), 2010 (W2H), 2512 (W3A)

Ambient Temperature
(°C)
For resistors operated at an ambient
temperature of 70°C or above, a power
rating shall be derated in accordance
with the above derating curve.
For resistors operated at a terminal part
temperature of described for each size or
above, a power rating shall be derated in
accordance with the above derating curve.
Please refer to “Introduction of the derating
curve based on the terminal part temperature”
on the beginning of our catalog before use.
