Bourns® Model PWR4412 Series Obsolescence

Bourns has announced the obsolescence of their PWR4412 series of metal element current sensing resistors.  Customers should not worry because Riedon has an exact drop-in replacement, our MSR series.  Here is the data sheet: https://riedon.com/media/pdf/MSR.pdf

We have these resistors stocked at Digikey.  The MSR series offers a very stable, cost-effective method for measuring currents in a wide variety of applications including motor drives, power supplies, and uninterruptible power sources.

MSR is a replacement for PWR4412

MSR alternate to the PWR4412

Below is a complete cross reference to the MSR:
