Riedon’s SL and S power resistors serve today’s expanding usage of surface mounted circuitry. The
SL Series is for low resistance requirements from 0.005 to 1 ohm. This low-profile design uses a
welded strip metal resistance element with very low inductance (0.5nH to 5nH) and low thermal emf.
The S Series uses a welded wirewound element for higher resistance applications to 50K ohms.
