   Miniature Style Resistors - MFS Series

MINIATURE STYLE RESISTORS  -  MFS 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.
