Ohmite Expands Series of Current Sensing Resistors
Current-sensing resistors.
Arlington Heights, IL — Ohmite Manufacturing Company has expanded its FC4L Series of four-terminal current sense resistors. This series, previously available in five-watt package sizes, is now also available in two-watt package sizes. +

Employing a Ni-Cu-Mn resistive element, the FC4L Series has a built-in four-terminal design with two larger electrodes for current management and two smaller electrodes for voltage measurement. This Kelvin type resistor is designed for automatic insertion and utilizes a metal foil construction, ensuring a very stable Temperature Coefficient of Resistance (TCR). In addition, it provides a tight tolerance (5 percent at 1 milliohm, 2 percent at 2 milliohms, and 1 percent at 3, 5, 10, 25, and 50 milliohms). Available in industry standard sizes, the FC4L Series functions for both high heat resistant use and low heat electromotive use. Its four-wire connection improves measurement accuracy by directly sensing a voltage drop across the resistor. This eliminates inaccuracies caused by voltage drops across resistor leads and printed circuit board (PCB) traces.

These current sense resistors can be used in a variety of battery powered electronic devices to mitigate concerns with battery life, recharging frequency, and overcharging risks.
