HSP resistors are thick film resistors in an aluminium housing. They are intended to be mounted on a heatsink to allow maximum dissipation. Thick film resistors have virtually no inductance and are therefore ideally suited for snubbers in switching circuits. HSP resistors have its connections parallel to the heatsink. HSV have its connections in vertical position. Thick film resistors can be produced with 15%, 3% or 1% tolerance on Ohmic values.
