SMW The patch winding Resistance

SMW The patch winding Resistance

Product catalog summary

Specifications:
The document outlines the dimensions and specifications for SMW resistors, including types 2W, 3W, and 5W with specific measurements for dimensions A, B, C, D, Emax, and FSMW. The resistance range is specified from 0.1Ω to 10KΩ with a tolerance of ±1% or ±5%.

Features:
The resistors are flameproof with a UL94V0 molded package, resistant to heat, humidity, and insulation. They are designed for automatic surface mounting, offering excellent mechanical strength and electrical stability, and help reduce assembly costs.

Ordering Information:
The ordering code includes the type (SMW Resistor), rated power (2W, 3W, 5W), tolerance (F=±1%, J=±5%), and resistance values (e.g., OR100=0.1Ω).

Electrical Performance:
The resistors have a resistance temperature coefficient of ±20 ppm/℃, can handle a short time overload of 5 times the rated wattage for 5 seconds, and operate within a temperature range of -55℃ to +200℃. They have an insulation resistance of 10,000 MΩ and maintain performance over load life and moisture-proof load life conditions.

Reference Standards:
The document references JIS C 5201-1 standards for testing and performance criteria.

Derating Curve:
A derating curve is provided to illustrate the percent rated power against ambient temperature, indicating performance adjustments required at different temperatures.
