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
RL3264-R050
Voltage pulse is applied to the test samples mounted
on the test board.
RL1632-R050
After each pulse, resistance drift is measured. Pulse
