Frequently Asked Questions
What makes the SRQ-HJ-04 suitable for both optical and power electronics applications?
The SRQ-HJ-04 features a flat, precision-machined base that provides reliable thermal contact across different component footprints. Its mounting pattern and fin geometry are designed to accommodate the thermal profiles of both optical transceiver modules and surface-mount power components on standard PCB layouts.
Is the SRQ-HJ-04 RoHS compliant?
Yes. The SRQ-HJ-04 is manufactured using RoHS-compliant aluminum alloy and surface treatment processes, making it suitable for use in telecom, industrial, and enterprise networking equipment that must meet EU RoHS and similar environmental compliance requirements.
What fin pitch does the SRQ-HJ-04 use, and how does it affect airflow?
The SRQ-HJ-04 uses an optimized fin pitch that balances surface area and airflow impedance. A tighter pitch increases heat transfer area but raises pressure drop; the SRQ-HJ-04's geometry is tuned for typical chassis fan speeds, ensuring effective cooling without excessive flow restriction.
