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.
