BTC-SJ SMT Power Jumper

Surface-mount power jumpers bridge PCB traces. Brass, copper and nickel-undercoat/tin options depend on the model drawing. Check board clearance, pads, pickup area and reflow process. The catalog reference of 20A–30A is for initial selection, not a rating for every PCB and cooling condition.

Surface mount PCB jumpers: span, clearance and tape

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.

Parameters to confirm before an enquiry
ItemInformation and conditions
Span and overall lengthThe 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 assemblyProvide 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 numberThe 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.

How should the catalog 20 A to 30 A figure be used?

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.

Can a power jumper replace a zero-ohm resistor?

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.
