Littelfuse offers durable and stable surface mount current sense resistors for a variety of power management applications.
The WSTC and WSTM series provide ceramic and epoxy substrate options. They include resistors from 1 to 499 milliohms with ratings up to 4 watts. The WLTC and WLTM are reverse geometry versions that offer lower ESL and increased power ratings for the same resistance and case size.
WPB and WPC series resistors are 2 and 3 watt current sense resistors in 2512 packages, with resistance values down to half a milliohm to minimize loss in higher power applications.
L4CA, L4CC, and L4CL series resistors are four-terminal current sense resistors that offer separate voltage sensing terminals for Kelvin measurements in applications that require greater accuracy. They’re offered with values down to 0.5 milliohms, tolerance down to 0.5 percent , and power ratings up to 1 watt.
