Dimensions
| Size | Type | Length L(mm) | Width W(mm) | Thickness T(mm) | Electrode Width E(mm) |
| 2512 | Large Electrode | 6.40.2 | 3.20.2 | 0.80.08 | 2.20.2 |

Power Derating Curve
Maximum load power should be reduced when operating in ambient environments above 70C, as indicated by the derating curve.
Rated Current Calculation
I = P/R, where I is rated current (A), P is rated power (W), and R is resistance (ohm). If the calculated current exceeds the maximum working current for a specific type, the maximum working current is the limiting factor.
