Frequently Asked Questions
Can multiple power devices be mounted on a single SRQ-XJ-22?
Yes. The SRQ-XJ-22 mounting surface is sized to accommodate multiple discrete devices or a combination of devices and modules. When mounting multiple components, ensure thermal interface material is applied uniformly and account for the cumulative power dissipation in your thermal resistance calculations.
What fin density does the SRQ-XJ-22 use, and how does it affect airflow?
The SRQ-XJ-22 uses an optimized fin pitch that balances surface area for heat transfer against airflow impedance. Tighter fin spacing increases surface area but raises pressure drop, which can reduce airflow in fan-cooled systems. The selected geometry suits both natural convection and moderate forced-air applications.
Is the SRQ-XJ-22 suitable for EV charging infrastructure applications?
Yes. EV charging stations require reliable thermal management for high-power switching devices operating in variable ambient conditions. The SRQ-XJ-22's robust construction and thermal performance make it well-suited for this application. Confirm your power dissipation and ambient temperature requirements with CZT for proper sizing.
