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.
