Industrial / Heat Sinks
SRQ-SLB-05
The SRQ-SLB-05 is an extruded aluminum heat sink designed to handle elevated thermal loads in industrial environments. Its wider fin spacing accommodates natural convection airflow, reducing reliance on forced cooling. Suitable for high-current rectifiers, IGBT modules, and ruggedized power electronics.
Key Features
- Extruded aluminum construction handles elevated thermal loads in industrial environments
- Extended fin height increases convective surface area for high-power dissipation
- Robust base plate supports heavy power modules and mechanical fastening
- Suitable for continuous-duty operation in high-ambient-temperature conditions
- Compatible with forced-air cooling to further reduce thermal resistance

Frequently Asked Questions
What environments is the SRQ-SLB-05 rated for?
The SRQ-SLB-05 is designed for industrial environments where elevated ambient temperatures, vibration, and continuous-duty operation are common. Its extruded aluminum construction and robust base plate make it suitable for factory automation, energy, and heavy equipment applications.
How does forced-air cooling affect the SRQ-SLB-05's performance?
Adding forced airflow across the SRQ-SLB-05 fins can reduce thermal resistance by 40–60% compared to natural convection, depending on airflow velocity. This allows the heat sink to handle significantly higher power dissipation without increasing its physical size.
What fastening methods are recommended for mounting power modules to the SRQ-SLB-05?
M3 or M4 screws with appropriate torque are recommended for mounting power modules to the SRQ-SLB-05 base plate. Always apply thermal interface material between the module and base, and follow the device manufacturer's recommended mounting torque to avoid package stress or cracking.
