Frequently Asked Questions
Can the SRQ-SLB-10 handle continuous high-power dissipation without forced airflow?
The SRQ-SLB-10 is designed for demanding thermal environments and performs well under natural convection for moderate loads. For sustained high-power dissipation above the natural convection limit, adding a fan to force airflow across the fins significantly reduces thermal resistance and extends safe operating range.
What materials and surface treatments are used on the SRQ-SLB-10?
The SRQ-SLB-10 is extruded from 6063-T5 or equivalent aluminum alloy, offering a good balance of thermal conductivity and machinability. An anodized surface finish is standard, improving corrosion resistance and increasing surface emissivity to enhance radiative heat transfer in enclosed installations.
How many power devices can be mounted simultaneously on the SRQ-SLB-10?
The wide base of the SRQ-SLB-10 supports multiple TO-247 or TO-218 devices in a row. Exact device count depends on individual package tab dimensions and required electrical isolation spacing. Review the dimensional drawing and ensure adequate creepage distance between isolated device tabs.
