Working with it

Hand-soldering Beginner
Commonly holds Transistors, mosfets, small ics and regulators

Supplied in

The part's orientation in its carrier sets the pickup angle — the converter corrects that rotation for your machine.

Placement rotation

Parts in this package are typically taped at an orientation that needs a +180° correction from the community rotation table (SOT-143). The converter applies this to matching parts automatically — verify against your own footprint library.
