Low resistance chip resistors (long side terminal type)
■
This series includes(some of) former PRL/RL series
Features
●
The distinctive structure that encourages heat dissipation and radiation limits
the rise of the surface temperature, allows the realization of smaller sizes, and
reduces influence of heat on surrounding components. Low ESL contributes
to less noise. This product also withstands temperature cycles very well.
Applications
●
PCs, power sources, inverters, automotive electronics, adaptors and
industrial machining equipment.

Test procedure
Voltage pulse is applied to the test
samples mounted on the test board.
After each pulse, resistance drift
i s m e a s u re d . P u l s e v o l t a g e i s
increased until the drift exceeds
+/-0.5%. The power at that voltage
is defined as the maximum pulse
power.

These high-power low resistance chip resistors are designed to dissipate heat efficiently
through the land patterns on circuit boards. The actual temperature of the surface of
the resistor is dependent upon the dimensions and the shape of the land patterns.
