SRQ-CC-01 Heat Sink
Model:SRQ-CC-01
The SRQ-CC-01 is a precision-engineered heat sink designed for thermal management of high-power optical transceiver modules and networking ASICs in data center and telecommunications equipment. Manufactured from high-conductivity aluminum alloy, this heat sink provides efficient heat dissipation for SFP+, QSFP, and OSFP transceiver cages operating in thermally demanding environments such as high-density switch line cards and optical transport nodes. Its optimized fin geometry maximizes surface area for convective cooling while maintaining a compact profile compatible with standard transceiver cage form factors.
Key Features

Frequently Asked Questions
What is the thermal resistance specification of the SRQ-CC-01?
Thermal resistance values depend on airflow conditions and contact interface quality. CZT provides thermal characterization data including junction-to-ambient resistance under specified airflow velocities. Contact CZT for detailed thermal simulation data and application-specific performance validation support.
Is the SRQ-CC-01 compatible with standard QSFP28 and CFP module form factors?
The SRQ-CC-01 is designed for high-power optical transceiver modules and is dimensioned to interface with common module form factors. Compatibility with specific QSFP28, CFP, or proprietary modules should be verified against CZT dimensional drawings for your application.
What thermal interface material is recommended for use with this heat sink?
CZT recommends phase-change thermal interface materials or high-conductivity thermal pads with conductivity of 3–6 W/m·K for optimal performance. The choice depends on module surface flatness, contact pressure, and reworkability requirements in your system design.
