RHA Series: Aluminum Housed Resistor

INTRODUCTION

•Small size, high power rating and performance

•Excellent space factor

•Strongly resistant to moisture, solvent &

insulation.

•Self-extinguish material is used in molding.

PART NUMBER EXAMPLE

N RHA 250W - 10R - J

•For non-inductively wound, use “N” prefix on the part number.
