Low resistance chip resistors
(short-side terminal)
■RL
series
Features
・
Innovative structure that takes consideration of heat dissipation suppress the surface
temperature enabling the small sizes reducing the influence of heat on surrounding
components.
Applications
・
PC power sources, inverters, automotive electronics, adopters, industrial machines

Test procedure
Voltage pulse is applied to the test samples mounted
on the test board.
After each pulse, resistance drift is measured. Pulse
voltage is increased until the drift exceeds +/-0.5%.
The power at that voltage is defined as the maximum
pulse power.
