Description

INTRODUCTION:
The resistance temperature coefficient of carbon film resistors is relatively high. Their resistance value changes inversely with temperature. But, as they are big in volume, causing quick dissipation of heat and low temperature rise, they are good enough in quality stability and reliability, and are therefore popularly used in consumer electronic appliances. In addition to the above general features, our CR series carbon film fixed resistors have the following features in particular. 　

FEATURES:

• Automated mass production, low prices.
  
• Selected superior quality materials to ensure stability and reliability.
  
• Variety of packaging-bulk, strip pack, 26mm and 52mm tape and reel, cut and formed, or radial Panasert / Avisert.
