Large Size Flat Chip Resistors Strengthen Power Rating

High Power Rating Flat Chip Resistor/KOA

KOA's 2512inch(6332mm) thick film chip resistors now achieves power rating 2W at 95℃, by terminal part temperature.
Wide terminal type 1020inch(2550mm) offers 2W and 1225inch(3263mm), 3W.
Anti-sulfur type of above series also releases high power rating type.
Application Examples: Power Supply Circuits, industrial robots, motor control circuits
