With the extended resistance range and high-temperature rating, the resistors can be specified for operation in harsh environments. SQP Cement Wirewound resistors feature a resistance range from 0.1Ω to 3KΩ, while SQP Cement Film Resistor have a resistance range of 80Ω to 150KΩ.
SQP Cement resistor's feature ideal specifications for high volume and high-temperature applications. Frequently used in power supplies, motor controllers, and automotive applications, these products can be custom tailored to individual needs.
Standard tolerances for both devices are to ±5%, with TCRs ≤300ppm. JDC is equipped to design and produce custom components to meet many design and reliability demands.
