NSW Damping Resistor

Product catalog summary

Overview: The document provides technical specifications and details for the NSW Noise Suppressor Wirewound Resistor, manufactured by Shenzhen KWX Electronics Co., Ltd. It outlines the applications, features, ordering information, dimensions, construction, performance characteristics, and typical frequency response of the resistor.

Applications: The NSW series is designed for use in automotive ignition systems to reduce radio frequency interference (RFI) caused by electrical discharges in petrol engines of cars and motorcycles. These resistors help ensure compliance with current legislation aimed at reducing such disturbances.

Features: The resistors offer high resistance volume and reliability. They are available in various power ratings and resistance tolerances, with a temperature coefficient of resistance (TCR) of ±150ppm/℃.

Ordering Information: The ordering code includes the series name (NSW), power rating (2W, 3W, 4W, 5W), resistance tolerance (J=±5%, K=±10%, M=±20%), resistance value (e.g., 1K0 for 1KΩ), TCR, and packing type (box).

Dimensions and Construction: The resistors are constructed with a copper cap, glass fiber, and alloy wire. Dimensions vary based on power rating, with specific measurements provided for each type.

Performance Characteristics: Key performance metrics include short time overload, inductance, load life, terminal tensile strength, high voltage pulses at high frequency, operating temperature range (-40℃ to 250℃), and dielectric strength. Specific test methods and specifications are detailed for each characteristic.

Typical Frequency Response: The document includes a graph showing impedance versus frequency for various resistance values, illustrating the typical frequency response of the resistors.
