Mounting Detail
The MPT resistor series are a range of T0220 packaged, low inductance thick film
power resistors which complement the thin film MPR series.
This small size, high power device packaged in five case sizes are ideally suited
to applications where high power dissipation yet small size are key design
requirements. The MPT resistor series are the ideal solution for small snubber
circuits, the output side of high speed pulse generators and low inductive resistor
requirements in switch mode power supplies.
