IRM Series Description

Introducing the IRM resistors, meticulously designed to meet the stringent demands of industrial applications. Housed in durable aluminum and engineered for efficient chassis mounting, the IRM series offers versatile power ratings ranging from 330W to 750W in free air and 600W to 1200W when heat sink mounted.

Engineers can leverage a broad resistance range from 0.1 to 160Ω (inductive) and 0.1 to 48Ω (non-inductive), coupled with tolerance options of ±1, ±2, ±5, and ±10 percent, providing a tailored solution for various applications. The maximum temperature coefficient of resistance (TCR) is capped at 260 ppm/°C, ensuring stability across a wide temperature range of -55℃ to +200℃.

IRM resistors find their niche in braking and snubber applications, motor drives, and power sources for industrial equipment, showcasing their adaptability in diverse engineering scenarios. Their robust design and high-performance characteristics make them a reliable choice for critical projects.

For those seeking UL-approved alternatives, the ULM series complements the IRM lineup. While maintaining the same high-performance standards, the ULM series holds UL approval, providing an additional layer of confidence for engineers prioritizing compliance with the highest safety standards in their industrial endeavors.
