| General Data | Specification |
|---|---|
| Nominal Resistance Tolerance | 5%, 10% |
| Climatic Category | 55/155/21 |
| Low Air Pressure | 8.5kpa |
| Stability Grade | 5% |
| Resistance Change Limit | Long-term test: (5%R+0.1); Short-term test: (1%R+0.05) |
| Temperature Coefficient | Standard type 350 ppm; Semi-fusing type, explosion-proof type, high lightning surge type: 35001500 ppm |
| Rated Current | I(A) = P(W)/R() |
| Derating Curve | Rated power is the maximum value for continuous operation at 70. Power derating is required above 70 as per the curve. |
| Fusing Characteristics | Defined as significant increase in resistance when subjected to specified overload, causing current to drop below 1/50 of the initial test current. Fusing time is the duration from overload application to fusing. |
| Fusing Time Requirements | Under specified rated current multiples overload conditions, fusing time must comply with the tables provided (Table 3-1 for standard and high lightning surge types, Table 3-2 for explosion-proof types, Table 3-3 for semi-fusing types). Fusing time can be customized upon request. |
| Impact Resistance | Test involves repeated switching (2s on, 2s off) for 100 cycles. Test resistor should not become open circuit. Capacitor C selection based on customer requirements (default 10uF). Resistor R value selected based on circuit, with 20W power rating and 0.8 power factor (for resistors under 10W, typically 20W, 5.1K 5%). |
| Main Test Items, Methods, and Requirements | As per Table 4. Includes resistance, short-time overload, solderability, voltage proof, heat resistance, rapid temperature change, endurance, lead strength, vibration, climatic sequence, and accidental overload. Specific requirements for resistance change, surface coverage, insulation, etc., are detailed in the table. |
| Taping Style and Dimensions | Refer to Figure 4 and Table 5. |
| Sleeve Product Style and Dimensions | Refer to Figure 5 and Table 6. Sleeve dimensions can be customized. |
| Molded Style and Dimensions | Refer to Figure 6 and Table 7. Molded shape and dimensions can be customized. |
| Model Specification Naming Convention | Example: RXF 1W S 10 J. Includes rated power, resistance tolerance (J: 5%, K: 10%, M: 20%), nominal resistance (E24 series), and color code for resistance marking. |
| Color Code Markings | Details provided for first digit, second digit, third digit, multiplier, and tolerance for various colors (Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Gray, White, Gold, Silver, Plain). |
| Packaging Method | Inner box: 1K/reel. Outer box packaging details not specified. |
