Carbon Film Fixed Resistors:

The resistance temperature coefficient of carbon film resistors is relatively highly. 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 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:-

• High quality performance
• Great economy
• Flame retardant type available
• Automatically insert-able
