Current Sensing Resistors

Sudden current or voltage changes are often hazardous to electronic products. For example, transients or surges that reach microprocessor or memory components can destroy those expensive parts, and wipe out critical programming and data. Many electronic products now include surge protection circuits.

In these circuits, low value resistors sense when the current is too high so that measures can be taken upstream before the excess current causes damage. Wirewound resistors are a popular choice for these applications. They are inexpensive, available in low resistance values, have low temperature coefficients and good surge-handling capability. Riedon has served this application for years with their “LO OHM” power resistors.

Riedon’s SL resistors add an additional application advantage. We designed them for PC board surface mounting to satisfy the growing demand for new high density boards fabricated with automated pick-and-place equipment.
