Sulfurization-proof Type Wide Terminal Chip Resistor
Hokuriku Electric Industry Co.,Ltd
【Model Number】
WCRES**
【Features】
■This is
high power type sulfurization-proof by wide terminal.
■
Use of pecial material for top electrode
provides
excellent sulfurization characteristic.
■By
high power capability, reduction of mounting area
is possible.
■By making
terminal wide side (terminal area increased)
,
higher reliability at solder joint
was realized.
■Large terminal area provides
excellent heat radiation
,
and help
suppress heat generation of circuitry.
■Europe RoHS compliant product.
