# SMM02070C2709FBP00

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

SMM02070C2709FBP00 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 termination cap with pure tin plating, one end of the 0.16 Ω to 10 MΩ resistive element, rated 1.0 W at 70 °C and 350 V max operating voltage. |
| 2 | 2 | passive | Second nickel-plated steel termination cap with pure tin plating, other end of the resistive element, interchangeable with the first terminal because the resistor is non-polarized. |
