# NCP21XQ102J03RA

**Murata Electronics** · NTC Thermistors · 0805

NCP21XQ102J03RA from Murata Electronics, in a 0805. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Thermistor terminal 1. Non-polar plated end termination; resistance between terminals 1 and 2 is nominally 1kΩ ±5% at 25°C, decreasing with rising temperature per the NTC B-constant of ~3675K. |
| 2 | 2 | passive | Thermistor terminal 2. Non-polar plated end termination; resistance between terminals 1 and 2 is nominally 1kΩ ±5% at 25°C, decreasing with rising temperature per the NTC B-constant of ~3675K. |

## CAD (KiCad official)

- Symbol: `NCP21XQ102J03RA`
- Footprint: `Resistor_SMD:R_0805_2012Metric`
- 3D model: 0805 (KiCad packages3D, STEP)
- 3D model files: `ncp21xq102j03ra-etched.step` / `ncp21xq102j03ra-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ncp21xq102j03ra.step` / `ncp21xq102j03ra.glb` are the bare package body.
