Frequently Asked Questions
What power dissipation levels can the SRQ-XJ-17 handle continuously?
The SRQ-XJ-17 is engineered for sustained high-power operation in industrial environments. Exact wattage capacity depends on airflow conditions and mounting configuration. Contact CZT with your thermal load and ambient temperature requirements for a detailed thermal resistance analysis.
Is the SRQ-XJ-17 suitable for outdoor or harsh industrial enclosures?
Yes. Its heavy-duty construction is designed to perform reliably in demanding industrial settings, including environments with elevated ambient temperatures, vibration, and dust. For outdoor deployments, ensure the enclosure provides adequate IP protection for the overall assembly.
What thermal interface materials are recommended for the SRQ-XJ-17?
High-performance thermal grease or phase-change pads with thermal conductivity of 3 W/m·K or higher are recommended to minimize contact resistance between the device and heat sink mounting surface. Ensure the mating surface is flat and clean before assembly.
