Cement Resistors
SQP Series
Featuring a heat-resistant ceramic housing filled with non-flammable cement, the SQP Series utilizes a classic axial horizontal lead configuration. Resistance values below 100Ω use a robust wirewound core for excellent surge resistance, while resistance values above 100Ω use a stable metal oxide film core. With a wide operating temperature range from -55℃ to +275℃, the series provides excellent heat dissipation and instantaneous overload protection.

Technical FAQ for R&D and Procurement
Q: How are the two core materials (Wirewound vs. Metal Oxide Film) used in the SQP Series Cement Resistors?
A: The SQP Series uses an optimized core structure according to the resistance value. For resistance values below 100Ω, a wirewound core is used to provide greater high-current handling and pulse protection capability. For resistance values above 100Ω, a metal oxide film core is used to provide a wider high-resistance range together with excellent high-temperature stability.
Q: What are the heat dissipation performance and operating temperature limits of this Cement Resistor Series?
A: The SQP Series features a heat-resistant ceramic housing filled with flame-retardant cement and supports an operating temperature range from -55℃ to +275℃. It provides excellent heat dissipation and instantaneous overload capability, making it highly suitable for high-power supplies and industrial equipment.
Q: What resistance tolerance options are available for SQP Horizontal Cement Resistors?
A: The standard resistance tolerance for this series is ±5%. For advanced control circuits requiring more precise resistance matching, a customized ±1% precision tolerance option is also available.
