Where To Use KNP Carbon Film And CF Wire Wound Resistors?
Carbon film resistors 1/4W and wire wound resistors are two widely used electronic components. So, where to use carbon film and wire wound resistors?
Carbon Film Resistor vs Wire Wound Resistor
KNP High Stability Carbon Film Resistor:
Featuring a wide resistance range, low cost, and compact size, they are suitable for low-to-medium power applications:
1. Consumer Electronics
TVs, radios, and laptops (used in audio circuits);
Microwaves, refrigerators, and air conditioners (applied in control panels and sensor circuits).
2. Automotive Electronics
Non-core control circuits, such as instrument panels and door lock systems.
3. Industrial Control
General PLC interface circuits.
CF Wire Wound Resistor:
Wire wound resistors 1W / 2W / 5W / 10W are wound with metal alloy wire, they offer advantages of high-power handling, high precision, and low temperature coefficient:
1. Industrial Electrical Equipment
Electric welders, frequency converters, and braking circuits, etc.
2. Automotive Electronics
Automotive air conditioning compressor drives, engine control units (ECUs), etc.
3. Aerospace
Satellites, spacecraft, and military communication equipment.
4. Medical Equipment
Magnetic Resonance Imaging (MRI) machines, ultrasonic diagnostic equipment, etc.
