IRS 30-50W Slim Series Metal Clad Resistor
Slim profile, aluminium housed
Chassis-mounted for efficient heat dissipation
100% RoHS compliant
Compact design for space-constrained installations
What is the IRS 30-50W Slim Metal Clad Resistor?
The IRS is a slim-profile, aluminium-housed, chassis-mounted metal clad resistor rated at 30W and 50W, covering a resistance range of 1Ω to 500Ω. With tolerances as tight as ±0.5% and a TCR of 260 ppm/°C max, it is fully RoHS compliant. Its low-profile design makes it ideal for applications where panel space is limited, including compact motor drives, servo amplifiers, and space-constrained industrial enclosures.
