SMD Resistors
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 鹵1% is offered between the
resistance values 200 milli ohms
and 10 ohms.

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.
