Select surface mount PCB jumpers by span A, overall length B, width and board clearance. Check the BTC-SJ catalog clearance of 1.8 mm after soldering, including underlying traces, pad positions and insulation requirements. Test operating current and temperature rise on the intended PCB and cooling arrangement.
| Item | Information and conditions |
|---|---|
| Span and overall length | The BTC-SJE182BTR catalog lists span A as 10.70 mm and overall length B as 14.10 mm. Check both dimensions separately and use the model drawing for pad positions and tolerances. |
| Clearance and assembly | Provide obstacle height, pad dimensions and required gap in mm. Review the catalog 1.8 mm board clearance with solder volume, assembly variation and a physical sample. |
| Tape-and-reel part number | The table distinguishes BT bulk and BTR reel part numbers; BTC-SJE182BTR lists 24 mm tape. Confirm feed orientation, pickup surface and reel quantity when requesting a quote. |
Use it for initial screening, then validate permitted temperature rise with continuous or pulsed current, PCB copper, solder joints and ambient temperature. Specify test conditions and acceptance methods for production purchasing.
Check footprint, pads, vertical clearance and current conditions. The elevated BTC-SJ bridge has different geometry from resistor packages such as 0402 or 0603; a replacement requires layout and assembly review.
An SMT assembly option for reducing manual wire bridges; confirm dimensions and soldering process.
Share dimensions, material, quantity and PCB assembly requirements. Sample costs, packaging and lead time are confirmed for the selected model.
