Type RL73 Series

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.
