KT Series Reed Relay
The KT Series is a high-voltage, high-insulation reed relay designed for precision switching in demanding applications requiring elevated isolation and low leakage. Capable of switching up to 1,000 VDC, with breakdown voltages up to 4.5 kVDC and isolation voltages up to 7 kVDC, the KT Series delivers robust performance in compact surface-mount (SMD) and through-hole (THT) formats.
Encapsulated in a rugged thermoset overmolded package, the KT Series features SPST-NO (Form A) contact configurations and supports coil voltages of 5 VDC, 12 VDC, and 24 VDC. With insulation resistance exceeding 10¹³ Ω, it ensures ultra-low leakage currents, making it ideal for high-voltage switching in medical, test & measurement, and energy systems. Tested to AEC-Q200 standards and UL listed, the KT Series is a reliable solution for high-performance designs.
