CMB02070X1001GB200 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 | One of the two nickel-plated steel termination caps with matte tin plating on the CMB 0207 MELF resistor body (L 5.8 mm, D 2.2 mm), rated up to 500 V ACRMS/DC operating voltage. |
| 2 | 2 | passive | The other termination cap of the CMB 0207 carbon film MELF resistor, which has 1.0 W rated dissipation at P70 and a -55 °C to 155 °C operating range. |
