Precision High-Voltage High Value Resistor (HI82) Radial-Lead

The high performance high-voltage applications require the use of high voltage resistors in applications with long-term stability and good temperature coefficient. DeMint Electronics has introduced ultra-stable high-precision HI82 high voltage resistors to meet these needs.

DeMint's unique precision full film and serpentine transfer pattern (serpentine patterns design), using a specifical high speed fine-line thick film dispensing system, developed a series of high voltage application resistor components with excellent performance.Especially in smaller sizes and higher resistance-value components.

Through the use of alloy ruthenium paste material, and 95% high aluminum planar ceramic chip, DeMint can control the manufacture of very precise precision and stabilize the performance parameters of important high-voltage operating temperature range. (HI82) thick film resistor combined with close tracking design, with low current noise, linear current voltage, low TCR, high temperature durability, wide resistance range, long-term stability, and low-cost advantages.

DeMint HI82 ultra-precision high-voltage resistors conform with RoHS and lead-free standards and provide more competitive prices and fast delivery service. For technical specifications and special applications, please contact your DeMint's sales representative.
