Bourns® Power Resistors
How to Order
As power densities increase, there is a continued increase in the
demand for resistors, which can withstand higher amounts of
power in as small a form factor as possible.
The PWR220-F series is through-hole and surface mount planar
thick film power resistors which when properly mounted on heat
sinks can dissipate up to 50 W of DC power. These resistors are
designed for use in applications where sudden surges in power
need to be safely discharged, such as snubber resistors in inverter
drives, welding machines or emergency power systems.
For power electronic applications such as current measurement
of electricity meters or emergency battery chargers, the
PWR4412 series offers all of these characteristics with a TCR of
20 PPM and power ratings of up to 5 W.

Where specialty current measurement resistors are required with
very tight resistance tolerance TCRs and high power, Bourns
offers metal foil on ceramic resistors.

4 pin Kelvin configurations.
The PWR10020 is a high current shunt with 60 mV output for a
rated current of 150 A DC. It is used in high-energy equipment
such as battery chargers for emergency backup systems.
In applications requiring both the qualities of wirewound
resistors such as the high pulse power capability and a surface
mount package, Bourns offers an alternative choice with the
PWR1913, PWR2615, PWR4525 and PWR6327 series.
