Thick Film Power Resistor Type MPT Series Key Features Small Size TO220 and TO247 Easy to mount Isolated moulded case Non Inductive High Power TO220 to 50W when mounted on suitable heatsink The MPT Resistor series are a range of T0220 and TO247 packaged, low TO247 to inductance thick film power resistors. This small size, high power device with 5 100W when models are ideally suited to applications where high power dissipation yet small mounted on size are key design requirements. The MPT Resistor series are the ideal solution suitable for small snubber circuits, the output side of high speed pulse generators and heatsink low inductive resistor requirements in switch mode power supplies.
