TO-style packages boost power resistor ratings

BI Technologies has introduced non-inductive planar thick- and thin-film power resistors housed in convenient TO-style packages for enhanced thermal performance in applications up to 140W.

The arrival of the MHP series reflects moves to reduce package parasitics in power electronic components to achieve higher power ratings and minimise thermal management overheads. The construction of the resistive element, combined with the integral metal flange of the TO-style packages, allows engineers to implement high-wattage circuits that require superior thermal management during operation. The metal flange allows direct mounting to a heatsink for efficient cooling, avoiding thermal saturation of the PCB by dissipating heat above the circuit board.

BI Technologies’ MHP series power resistors are available in power ratings from 20W to 140W in resistance values from 0.01Ω to 51kΩ, and include industry-standard powerpackage options from TO-126 to TO-247.
