SRQ-CC-06 Heat Sink
Model:SRQ-CC-06
The SRQ-CC-06 is an aluminum heat sink engineered for efficient thermal dissipation in optical transceiver and high-speed connector applications within data center and telecommunications equipment. Designed for integration with QSFP-28, QSFP-DD, and OSFP transceiver cages, this heat sink provides the thermal management necessary to maintain module junction temperatures within specification during sustained high-bandwidth operation. Its optimized fin pitch and base thickness balance thermal performance with the airflow characteristics of standard 1U and 2U rack-mounted networking equipment in enterprise and hyperscale data center deployments.

Frequently Asked Questions
What aluminum alloy grade is used in the SRQ-CC-06?
The SRQ-CC-06 uses a high-purity aluminum alloy selected for optimal thermal conductivity, typically AL6063 or AL1050 series, with thermal conductivity in the range of 160–200 W/m·K. Alloy selection is confirmed in the product datasheet and material certification documents available from CZT.
Does the anodized finish affect thermal performance?
Anodizing increases surface emissivity from approximately 0.05 for bare aluminum to 0.8–0.9, which meaningfully improves radiative heat dissipation in low-airflow environments. The thin anodize layer has negligible impact on conductive thermal resistance through the heat sink body.
Is the SRQ-CC-06 available in custom fin heights or base thicknesses?
Yes, CZT offers customization of fin height, base thickness, and overall dimensions for OEM programs. Custom tooling lead times and NRE costs apply. CZT engineering provides DFM review and thermal simulation support to optimize geometry for your specific power dissipation and space constraints.
