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 | IP+ | passive | Input current positive terminal (primary conductor). Pins 1 and 2 are shorted together externally. Part of the low-resistance (~1.2 mΩ) primary conduction path electrically isolated from the signal side. |+| 2 | IP+ | passive | Input current positive terminal (primary conductor). Pins 1 and 2 are shorted together externally to form the current input side of the primary path. |+| 3 | IP- | passive | Input current negative terminal (primary conductor). Pins 3 and 4 are shorted together externally to form the current output side of the primary path. Isolated from the signal-side pins by 2.4 kVRMS. |+| 4 | IP- | passive | Input current negative terminal (primary conductor). Pins 3 and 4 are shorted together externally. |+| 5 | GND | power_in | Signal ground reference for VCC, VOUT, and FILTER pins. |+| 6 | FILTER | passive | External filter capacitor pin used to set the output bandwidth. Cutoff frequency fc = 1/(2*pi*RF*CFILTER), with internal filter resistance RF(int) ~1.8 kΩ typ. Reducing bandwidth improves noise but increases response time. |+| 7 | VOUT | output | Analog output signal proportional to sensed primary current. For the -30UR5 (unidirectional) variant: VOQ = 0.5V at IP=0A, output swings 0.5V to 4.5V for 0..+30A with sensitivity 133.3 mV/A. Ratiometric to VCC. VOL max 0.3V, VOH min VCC-0.3V into RL >= 4.7 kΩ. |+| 8 | VCC | power_in | Positive supply voltage input. Nominal 5.0V (4.5V-5.5V range). ICC typ 14 mA, 20 mA max. A 0.1 µF CBYPASS capacitor between VCC and GND is required. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Magn Tek |+| Package | SOP-8 |+| Category | Sensor |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `MT9223CT-30UR520UR5`+- `MT9223CT-30UR5`+- `MT9223CT-30UR535UR5`+- `MT9223CT-30UR520BR5`+- `MT9223CT-30UR525BR5`+- `MT9223CT-30UR530BR5`+- `MT9223CT-30UR540BR5`+- `MT9223CT-30UR550BR5`++## CAD (KiCad official)++- Symbol: `MT9223CT-30UR5`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Magn Tek datasheet](docs/mt9223ct-30ur5-datasheet.pdf) (18 pp, sha256 `a6f5ef9a0d1a103e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
