resistors
RK73Z
features
• Wide lineup from 01005 to 2512 size
• Excellent heat resistance and weather resistance, because
of the use of glaze thick film as resistive film
• Suitable for both flow and reflow solderings
• Silver element
• 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 Tested: 0201(1H), 0402(1E), 0603(1J),
0805(2A), 1206(2B), 1210(2E), 2010(2H/W2H), 2512(3A/W3A)

Terminal Part Temperature
(°C)
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 derating curve.
Please refer to “Introduction of the
derating curve based on the
terminal part temperature” in the
beginning of our catalog before use.

Please ask us about the resistance characteristic of continuous applied pulse.
Please calculate One-Pulse Limiting Electric Power using upper limit of resistance (50mΩ or 100mΩ) for applied current.
The pulse endurance values are not assured values,so be sure to check the products on actual equipment when you use them.
