Frequently Asked Questions
What is the advantage of a direct-mount heat sink design like the SRQ-XJ-26?
Direct mounting eliminates intermediate thermal interfaces between the power module and heat sink, reducing the total thermal resistance path. This allows higher power dissipation within a given temperature budget or enables a smaller heat sink for the same power level compared to indirect mounting arrangements.
How does the SRQ-XJ-26 perform in low-airflow industrial enclosures?
The SRQ-XJ-26 fin geometry is designed to function effectively in the restricted airflow conditions typical of closed industrial enclosures. For very low airflow environments, natural convection performance data should be used for thermal sizing. Adding internal circulation fans significantly improves performance in sealed cabinets.
Are custom bolt patterns available for non-standard power module footprints?
Yes. CZT offers custom drilling and tapping services for OEM orders requiring non-standard module mounting patterns. Provide your module's mechanical drawing and mounting specifications, and CZT's engineering team will confirm feasibility and lead time for customized SRQ-XJ-26 units.
