Technical FAQ for R&D and Procurement
Q: What are the main features and application advantages of the KNP and KNP-S Series wirewound resistors?
A: KNP is the standard-size wirewound resistor, while KNP-S is the miniature-size version designed for high-density PCB layouts. The series uses Alloy Resistance Wire as the internal resistive element, providing excellent instantaneous overload capability and superior heat dissipation. It is particularly suitable for power supplies, motor control systems, and high-surge-current applications.
Q: What are the operating temperature range and flameproof coating specifications of this series?
A: This series supports a wide operating temperature range from -40°C to +275°C. The exterior is coated with Green Silicone that meets the UL94-V0 flameproof standard, providing enhanced protection and safety during high-temperature operation and extreme overload conditions.
Q: What resistance values and tolerance options are available for the KNP Series?
A: Standard resistance values follow the E24 series, with a standard resistance tolerance of ±5%. For circuit designs requiring higher resistance matching accuracy, customized tolerance options ranging from 1% to 5% are also available.
