**Vishay Intertech** · Chip Resistor - Surface Mount · MELF-0207

SMM02070C4701FBP00 from Vishay Intertech, in a MELF-0207. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | First nickel-plated steel end-cap terminal with pure tin plating of the 4.70 kΩ thin film MELF resistor; the part is non-polarized, rated 1.0 W at P70 and 350 V max operating voltage. |
| 2 | 2 | passive | Second end-cap terminal of the 4.70 kΩ thin film MELF resistor; interchangeable with the first terminal, with an operating temperature range of -55 °C to 155 °C. |
