Frequently Asked Questions
Is the SRQ-XJ-32 rated for use in protected outdoor enclosures?
Yes, the SRQ-XJ-32 is designed for both indoor and protected outdoor environments. Its anodized aluminum finish resists oxidation and mild humidity exposure. For outdoor use, it should be installed within an enclosure rated at minimum IP54 to prevent direct moisture and contaminant ingress.
What is the maximum continuous power dissipation the SRQ-XJ-32 can handle?
Maximum power dissipation depends on thermal resistance, ambient temperature, and target junction temperature. Contact CZT with your specific Rth requirement and operating conditions for a thermal budget calculation. Forced-air cooling can significantly extend the usable power dissipation range.
Does the SRQ-XJ-32 require any special mounting hardware?
The SRQ-XJ-32 uses standard M3 or M4 fasteners depending on the mounting configuration. No proprietary hardware is required. CZT recommends applying controlled torque to fasteners to ensure uniform contact pressure across the device mounting surface without warping the base.
