# MPMT1003AT1

**Vishay Intertech** · Resistor Networks, Arrays · SOT-23

MPMT1003AT1 from Vishay Intertech, in a SOT-23. 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 | R1_END | passive | Free end of resistor R1, whose other end connects to center tap pin 3; the schematic shows R1 between pins 1 and 3. |
| 2 | R2_END | passive | Free end of resistor R2, whose other end connects to center tap pin 3; the schematic shows R2 between pins 2 and 3. |
| 3 | CENTER_TAP | passive | Divider center tap, the common junction of R1 and R2, with 250 ohm to 100 kohm per resistor and 100 mW per resistor at +70 °C. |

## CAD (KiCad official)

- Symbol: `MPMT1003AT1`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `mpmt1003at1-etched.step` / `mpmt1003at1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mpmt1003at1.step` / `mpmt1003at1.glb` are the bare package body.
