AP851 50 Watts TO-220 High

Power Resistors

A high powerTO-220 style resistor package designed for high frequency emitter

circuits in switching power supplies. Also used in voltage regulation and low energy

pulse loading.

• 50 Watts at 25˚C case temperature on heat sink

• Single screw mounting to heat sink

• Moulded case for proctection and easy to mount

• Non-inductive design

• Electrically isolated case

• RoHS Compliant
