Miniature Style Resistors - CRS Series

Miniature Style Resistors - CRS Series

Power Rating:

1/4WS, 1/2WS, 1WS, 2WS, 3WS

FEATURES

Low cost, high performance.

High power with small size for significant space savings.

Excellent long - term stability.

Variety of packing - bulk, strip pack, 26mm and 52mm tape and reel, cut and formed or radial Pana.

INTRODUCTION

The miniature series has increased by 30% the Aluminum into the Ceramic Bar. They can offer excellent performance in applications where stability and uniformity of characteristics are desired in high terperature, resistant to humidity and shock testing.
