Frequently Asked Questions
What power dissipation range is the SRQ-XJ-38 suitable for?
The SRQ-XJ-38 is optimized for medium thermal loads, typically handling power dissipation in the 15–40W range depending on airflow conditions. Natural convection performance can be extended with forced airflow from a low-speed fan mounted above the fin array.
Is the SRQ-XJ-38 compatible with thermal interface materials?
Yes. The machined base surface is flat to within standard tolerances, making it compatible with thermal pads, phase-change materials, and thermal grease. A smooth base finish ensures consistent contact pressure and minimizes interface thermal resistance.
Can the SRQ-XJ-38 be used in a horizontal mounting orientation?
It can be mounted horizontally, though vertical fin orientation is recommended for natural convection to allow chimney-effect airflow. In horizontal installations, forced airflow is advised to maintain rated thermal performance and prevent hot spots.
