CCR Carbon‑Composition Resistor
Manufacturer: Guangdong Qingda Electronic Technology Co., Ltd
Product Overview
Carbon‑composition resistor (solid carbon resistor) CCR series is axial through‑hole fixed resistor, manufactured by compressing finely ground carbon powder with binder into solid resistive core. Different from film resistors, solid carbon resistors deliver outstanding pulse and surge withstand capability, excellent non‑inductive performance. They maintain stable performance under instantaneous heavy‑load and high‑pulse working conditions.
Guangdong Qingda Electronics provides complete CCR series specifications covering 1/4W, 1/2W, 1W, 2W. Products comply with RoHS requirements, available for standard bulk order and custom service.
Key Features
- Superior pulse & surge withstand capacity, great for instantaneous overload
- Near‑non‑inductive characteristic, suitable for high‑pulse circuits
- Compact axial lead structure, easy for through‑hole assembly
- Wide resistance range with multiple tolerance options J/K/M
- Reliable performance under harsh working environment
- RoHS compliant, lead‑free
Applications
CCR carbon‑composition resistors are widely applied in pulse electronic circuits, test & measuring instruments, industrial equipment, lighting systems, consumer electronics, high‑surge protection circuits and general‑purpose electronic devices.
