Flameproof silicone coated axial-leaded thick-film resistors increase reliability

Vishay has introduced a new series of axial-leaded thick-film planar through-hole resistors featuring a flameproof silicone coating for increased reliability. Offering high voltage handling up to 15kV, the FHV series devices are optimized for pulse applications in industrial power supplies and laboratory / medical equipment. The devices released today feature a robust construction consisting of a high-temperature fired cermet film resistive element and high-purity 96 % alumina core. With their flameproof silicone coating, the resistors are designed to withstand overload conditions without flame or mechanical damage. Offering a non-inductive design in nine case sizes, FHV Axial series devices feature a wide resistance range from 100ohm to 10 GO, tolerances down to ± 1 %, low TCR to ± 100 ppm/C, and power ratings from 0.25W to 4W at +70C and 0.125W to 2W at +125C. The RoHS-compliant, halogen-free resistors offer tin-plated copper terminations. Matched sets are available on request, says the company.
