75 Ohm 200W Milwaukee Resistor | High Dissipation Industrial
The 75 Ohm 200W Milwaukee Resistor is a tubular passive component designed to withstand severe operating conditions. Its construction features a premium alloy resistive wire precision-wound over a high-purity steatite ceramic core, allowing efficient thermal management.
El recubrimiento de esmalte vítreo (Vitreous Enamel) no solo protege el filamento contra la oxidación y la humedad, sino que también mejora el aislamiento dieléctrico. Este modelo específico de MRC (Milwaukee Resistor) es un estándar en la industria pesada debido a su capacidad para manejar picos de corriente sin degradación estructural.

Manufacturer History: Milwaukee Resistor (MRC)
Founded in 1944 in Milwaukee, Wisconsin, Milwaukee Resistor Corporation has established itself as a leader in the manufacturing of high-power resistors. In 1999, it became part of the Post Glover Resistors family of companies, the world’s largest manufacturer of power resistors. Its products are renowned for being “built to last,” making them a preferred choice in sectors such as rail transportation, power generation, and heavy industrial automation. A component marked MRC is synonymous with precision American engineering.
(FAQ)
Is the resistor’s functionality guaranteed?
Yes, each unit has undergone a continuity test of the resistive element to ensure that the internal circuit is intact and delivers the specified 75 ohms.
Can it operate outdoors?
Although the vitreous coating is highly resistant, it is recommended for use inside ventilated enclosures to prevent the accumulation of corrosive contaminants on the terminals.
What is the maximum operating temperature?
Milwaukee Resistor vitreous enamel resistors can operate at surface temperatures of up to 350°C, although for extended service life it is recommended to operate them at 70% of their power rating if forced ventilation is not available.
