Frequently Asked Questions
What power dissipation range is the SRQ-YZ-15 designed for?
The SRQ-YZ-15 targets mid-range dissipation applications, typically 10–50W depending on ambient temperature and airflow. For accurate sizing, calculate required thermal resistance using Rth = (Tj_max - Ta) / P and compare against the product's rated specification.
Does fin orientation affect the SRQ-YZ-15's thermal performance?
Yes, significantly. For natural convection, fins should be oriented vertically to allow chimney-effect airflow. Horizontal fin orientation can reduce convective efficiency by up to 30%. Always mount the SRQ-YZ-15 with fins vertical unless forced airflow is present.
Is the SRQ-YZ-15 compatible with thermal interface pads?
Yes. The flat machined base is compatible with thermal interface pads, phase-change materials, and thermal grease. For production environments, pre-cut thermal pads offer consistent, repeatable contact resistance and simplify assembly compared to manually applied paste.
