Technical FAQ for R&D and Procurement
Q: What are the main differences between the CR/FCR and CR-S/FCR-S Series?
A: CR is the standard-size carbon film resistor, while CR-S is the mini-size version developed for high-density PCB layouts. Models with an “F” designation, such as FCR and FCR-S, feature a grey silicone flameproof coating, making them suitable for industrial equipment, power modules, and other applications with higher safety requirements.
Q: What are the standard resistance values and tolerance ranges for this carbon film resistor series?
A: The standard resistance range is from 1R to 10Meg in the E24 series, with a standard tolerance of ±5%. For circuit designs requiring higher signal accuracy, ±2% tolerance options are also available.
Q: What is the operating temperature range, and what coating materials are used?
A: This series supports a wide operating temperature range from -55ºC to +155ºC. Standard models use an epoxy insulating coating with a yellow-brown (beige) body, while flameproof models use a grey silicone coating. All versions feature a high-purity ceramic (Al2O3) core to ensure excellent long-term operating stability.
