Technical FAQ for R&D and Procurement
Q: What are the PCB layout advantages of the radial/vertical design used in the SQM Series Cement Resistors?
A: The SQM Series features a vertical lead configuration that allows the resistor body to stand vertically on the circuit board, significantly reducing the required PCB footprint. This makes it particularly suitable for high-density layouts, space-constrained industrial power supplies, and control modules.
Q: How does this series perform in terms of heat dissipation and low-noise characteristics?
A: This series uses a high-thermal-conductivity ceramic housing with heat-resistant silicone cement filling, providing excellent stability and superior heat dissipation under high-temperature conditions. It also features a very low electrical noise level to help maintain circuit sensitivity and reliable operating performance.
Q: Does the SQM Series offer non-inductive options? What tolerance specifications are available?
A: Yes. For specialized circuit designs requiring low inductance in high-frequency or high-pulse applications, non-inductive versions are available for specific resistance values. Resistance tolerances from 1% to 5% are available to provide engineers with flexible design options.
