Frequently Asked Questions
What are the advantages of passive cooling for industrial applications?
Passive heat sinks eliminate moving parts, removing the primary failure mode in active cooling systems. This is critical in sealed enclosures, remote installations, or environments where fan maintenance is impractical. The SRQ-XJ-20 delivers reliable, silent thermal management with zero ongoing maintenance requirements.
How does the SRQ-XJ-20 perform across wide ambient temperature swings?
The SRQ-XJ-20 is designed for consistent thermal performance across a broad ambient temperature range typical of industrial deployments. Aluminum's stable thermal conductivity across temperature ensures predictable junction temperatures. Verify derating curves against your worst-case ambient when sizing for your application.
Can the SRQ-XJ-20 be used in both horizontal and vertical mounting positions?
Yes, though vertical fin orientation is recommended for passive installations to maximize natural convection efficiency. Horizontal mounting is acceptable in forced-air or conduction-cooled enclosures. CZT can provide orientation-specific thermal resistance data to support your system thermal design.
