Low-Ohm Resistors Serve As Precision Current Sensors

Suited for a wide range of current-sensing applications, the LOB Series of molded axial leaded resistors have power ratings of 1W, 3W or 5W and resistance values down to 0.005(omega). They exhibit virtually no inductance in current sensing circuits and are rated for operation from -65°C to +150°C. These ultra-stable resistors can be used in switchmode and linear power supplies, automotive current-sensing circuits, voltage regulators and instrumentation. Typical pricing for LOB Series resistors starts at $0.15 each in production volumes for 1W device.
