Specifications:
The document outlines the dimensions and specifications for SMF High Power SMD Resistors. The dimensions are provided for different wattage types (2W, 3W, 5W) with specific measurements for parameters A, B, C, D, Emax, and FSMF. The resistance range is specified in ohms (Ω), and the maximum overload voltage is listed as 300V or 500V depending on the type.

Features:
1. Flameproof UL94V0 molded package, resistant to heat, humidity, and insulation.
2. Special design for automatic surface mounting.
3. Excellent mechanical strength and electrical stability.
4. Reduces assembly costs.

Ordering Information:
The ordering information includes the type (SMF Resistor), rated power (2W, 3W, 5W), tolerance (±1%, ±5%), and resistance values (e.g., 0.1Ω, 0.22Ω, 10Ω, 10KΩ).

Electrical Performance:
- Resistance Temperature Coefficient: ±200 ppm/℃
- Short Time Overload: 5 times of rated wattage for 5 seconds
- Rated Load: -55℃ to +200℃
- Insulation Resistance: 10,000 MΩ
- Load Life: 70℃ on-off cycle for 1,000 hours
- Moisture-proof Load Life: 40℃ 95% RH on-off cycle for 500 hours

Reference Standards:
The document references JIS C 5201-1 standards.

Derating Curve:
A derating curve is provided to illustrate the percent rated power against ambient temperature, indicating performance across a temperature range from -55℃ to 275℃.
