| H housings | Single-row housings for the required circuit count |
| Board headers | Matching board interfaces by orientation and circuit count |
| Crimp terminal | Phosphor bronze contact for 26–22 AWG wire |
| Centerline | 2.54 mm |
|---|---|
| Positions | 1–30 |
| Maximum current | 3 A per contact |
| Maximum voltage | 250 VAC/DC |
| Operating temperature | -25 °C to 105 °C |
| UL file | E364711 |
| Contact plating | Tin Plating |
| Housing resin / flammability | Nylon 66 UL94V-0 / PPO (model-dependent options) |
Choose the housing and header with the same circuit count, then match the terminal to 26–22 AWG conductors. Confirm the mating dimensions and board footprint on the applicable drawing.
