TE Connectivity are pleased to offer this thick film chip resistor for current sensing positions.

It has a special metal glaze resistive element and a nickel barrier layer beneath the solder to

prolong terminal life. Following the developments by semiconductor manufacturers in the

production of a range of IC's for battery charge management and low voltage power

supplies, the RL73 Series satisfies the demand for a low ohmic shunt resistor to act as a

current sensor.
