HVS Wire Wound Resistor

Product catalog summary

Overview: The document provides technical specifications and performance details for HVS Wire Wound Resistors, designed for high pulse voltage applications. These resistors are manufactured by Shenzhen KWX Electronics Co., Ltd.

Features:

Flameproof and insulating coating with non-flammable silicon-base, equivalent to UL94V-0.
Good heat durability, low temperature coefficient, low noise, and high overload power.
Stable long service life and compliance with Eu-RoHS standards.
Excellent performance in pulsed high voltage circuits.

Specifications:

Power ratings range from 1/4W to 40W.
Resistance range from 0.1Ω to 100KΩ.
Maximum working voltage varies from 300V to 700V, with pulse withstanding voltage up to 40KV.
Temperature Coefficient of Resistance (T.C.R) varies based on resistance value, from ±100PPM/℃ to ±600PPM/℃.

Construction: The resistors consist of a lead wire, cap, ceramic base, wire wound, marking or color code, and insulation coat.

Performance and Testing:

Resistance and T.C.R are within specified tolerances.
Short time overload and load life tests show minimal deviation from specified resistance.
Moisture resistance and temperature cycle tests ensure durability under various environmental conditions.
Insulation resistance exceeds 1,000MΩ.
Pulses withstanding voltage test involves a discharge cycle repeated 10,000 times with a test voltage of DC 10KV.

Applications: Suitable for circuits requiring high pulse voltage resistance, with detailed pulse diagrams provided for various HVS models.

Ordering Information: The document includes a guide for ordering resistors based on series name, power rating, resistance tolerance, and resistance value.
