Frequently Asked Questions
What power range is the SRQ-YZ-22 optimized for?
The SRQ-YZ-22 is designed for medium-power applications, typically in the 5–30W dissipation range under natural convection. With forced airflow, the effective dissipation capacity increases substantially. Consult the product datasheet or CZT technical support for Rth values at specific airflow velocities.
Is the SRQ-YZ-22 suitable for commercial as well as industrial applications?
Yes. The SRQ-YZ-22's design balances performance and cost for both commercial and industrial deployments. It meets the thermal and mechanical requirements of commercial HVAC, lighting, and building automation equipment while also being robust enough for light industrial control applications.
How does the black anodized finish improve the SRQ-YZ-22's performance?
Black anodizing raises surface emissivity to approximately 0.85–0.95, compared to 0.05 for bare aluminum. In still-air or low-airflow environments, radiative heat transfer can account for 20–30% of total dissipation. The black finish therefore meaningfully reduces thermal resistance without any design changes.
