KNP Wire-wound Resistors

Product catalog summary

Overview: This document provides technical specifications, features, construction details, and performance standards for KNP Wire Wound Resistors manufactured by Shenzhen KWX Electronics Co., Ltd.

Features:

Flameproof and insulating coating using non-flammable silicon-base, equivalent to UL94V-0.
Good heat durability, low temperature coefficient, low noise, and high overload power.
High stability and long life.
Compliance with Eu-RoHS standards.

Construction:

Components include lead wire, cap, ceramic base, wire wound, marking or color code, and insulation coat.

Specifications:

Power ratings range from 1/4W to 40W.
Resistance range from 0.05Ω to 100KΩ.
Maximum working voltage varies from 300V to 700V.
Temperature Coefficient of Resistance (T.C.R) varies based on resistance value.

Performance Requirements:

Resistance and T.C.R. must be within specified tolerances.
Short time overload and load life tests are conducted under specified conditions.
Moisture resistance and temperature cycle tests ensure durability.
Solderability and resistance to soldering heat are tested to ensure quality.
Insulation resistance must be greater than 1,000MΩ.
Flameproof tests ensure no obvious flaming or arcing.
