UC490 is a right-angle IEEE 1394 female PCB socket with six surface-mount signal contacts. Through-board shell tabs and two locating posts support its mounting arrangement. The signal footprint has six pads at 1mm pitch; the mating-contact arrangement has two rows of three with 2mm pitch along each row.
| Characteristic | UC490 |
|---|---|
| Interface | IEEE 1394 female; 6 contacts |
| Signal termination | SMT |
| Rated current | 1.5A |
| Rated voltage | 30V; AC/DC designation unspecified |
| Contact resistance | ≤50mΩ |
| Insulation resistance | 100MΩ; minimum/maximum designation unspecified |
| Dielectric withstand test | 100VAC for 1 minute |
| Insulator | PA66; material group I; UL94V-0 |
| Contact material | Copper alloy |
The dielectric withstand condition is a test value, separate from the working-voltage rating. A data rate and protocol revision are unspecified.
The three fields after UC490 select housing colour, shell plating and contact plating.
| Field | Code | Selection |
|---|---|---|
| Housing colour | B | Black |
| Shell plating | N | Nickel |
| 6 | Tin | |
| Contact plating | C | Selective 3µin gold |
Dimensions are in millimetres. The recommended PCB-layout tolerance is ±0.05mm. Use the SMT signal pads, post clearance holes and shell-tab slots together when preparing the footprint.
