Wide Terminal Type Chip Resistor
Hokuriku Electric Industry Co.,Ltd
【Model Number】
WECR**/WLCR**/WCR**
【Features】
■Due to wide side terminal,
high power handling was achieved.
possible）
(Compared to same size other type, 1½2 higher rank is possible）
■Due to high power capability,
number of resistors, its occupied area can be reduced.
■Due to wide side terminal structure,
solder joints hold high reliability.
■Wide side terminal structure has
effect of suppressing heat generation.
■１０½Ω½１ＭΩ,
wide resistance range
is covered.
■Europe RoHS compliant product
