Frequently Asked Questions
What is the typical thermal resistance of the SRQ-HJ-12?
Exact thermal resistance values depend on airflow conditions and mounting configuration. For precise figures, refer to the product datasheet or contact CZT engineering support. Generally, industrial-grade heat sinks in this series are rated for natural convection dissipation in the range of several watts per degree Celsius.
Can the SRQ-HJ-12 be used in vertically mounted orientations?
Yes. The fin orientation on the SRQ-HJ-12 is designed to support vertical mounting, which promotes natural convective airflow along the fin channels. Horizontal mounting is also possible but may slightly reduce passive cooling efficiency due to reduced chimney effect.
What surface treatment does the SRQ-HJ-12 have?
The SRQ-HJ-12 features an anodized surface treatment that improves thermal emissivity for better radiative heat transfer, while also providing corrosion protection suitable for industrial environments with humidity, dust, or mild chemical exposure.
