Technical Specifications
| Type | Rated Power (W) | Resistance Range (m) | TCR (ppm/) | Insulation Resistance (> M) | Size | Dimensions (mm) L x W x T | Max Current (A) |
| 1206 | 1W (up to 3W) | 1m~200m | 350 (1m), 50 (2m~100m), 50 (110m~200m) | >100 | 1206 | 3.200.20 x 1.600.20 x 0.600.20 | Calculated by I=P/R, capped by max working current |
| 2512 | 2W, 3W | 0.5m~500m | 50 (1m~4m), 350 (0.5m), 50 (2m~500m) | >100 | 2512 | 6.400.20 x 3.200.20 x 0.800.20 | Calculated by I=P/R, capped by max working current |
| 0805 | 0.25W, 0.5W | 1m~20m | 350 (1m), 50 (2m~20m) | >100 | 0805 | 2.000.20 x 1.250.20 x 0.600.20 | Calculated by I=P/R, capped by max working current |
Note: Rated current is calculated by I = P/R. If the calculated current exceeds the maximum working current for a specific type, the maximum working current shall be regarded as the rated current. Power derating is required for ambient temperatures above 70C.
