Key features
type RL73 series
The RL73 series has a special
metal glaze resistive element
and a barrier layer beneath the
solder to extend terminal life.
This product satisfies the
demand for a low ohmic shunt
resistor to act as a current
sensor. We can offer sizes and
tighter tolerances as "specials"
where demand justifies.
A ±1% is offered between the
resistance values 200 milli ohms
and 10 ohms.

Temperature Coeffificent of Resistance
Resistors with 1% tolerance will have a TCR of 100ppm/ °C
Resistors with 2% or 5% tolerance will have a TCR of 200ppm/ °C
Recommended Circuit Board Design
If this device is anticipated to run at full continuous power then action to improve the cooling should
be taken. This can be a metal substrate, copper pad left under the chip or an opening in the PCB.
