NLR Series with Heat Sink Provide Non-Inductive, High-Heat Dissipation
Writer：Microhm Page View：Date：2020-01-02
Microhm Electronics is now distributing heat sink devices with enhanced power size ratios, high stability and optimum heat dissipation. The Microhm NLR series are non-inductive, thick-film heat sink resistors coming in TO-220 or TO247 type packages. The resistances range from 10W to 140W. Resistances cover 0.01Ω to 51KΩ. Tolerance 1% and 5% are available.
Typical applications include switching power supplies and various types of pulse circuits. A miniature device, it features a plated copper heat sink, a high stability thick-film element, and tinned copper leads. It also has high temperature thermoset molding.
Custom models are available with variations in lead length, tolerances to 0.5%, and various temperature coefficients. The NLR Series’ terminal strength is tested with a 5-lb. pull and its solderability and solvent resistance meet MIL-STD-202 requirements.
