GCSP-103-05A-AL-PCM

The GCSP-103-05A-AL-PCM from GCS Thermal is a high-performance phase change material (PCM) designed to manage heat in compact and high-power electronic systems. It features a thin, grey PCM layer on an aluminum substrate, offering excellent thermal conductivity and easy application.

This material activates between 52°C and 65°C, where it softens and flows to fill microscopic surface gaps. This phase change dramatically reduces thermal resistance and improves contact between heat sources and heat sinks. With a thermal conductivity of 3.2 W/m K and thermal impedance of just 0.05°C-in²/W at 10 psi, it delivers efficient heat transfer in demanding environments.

GCSP-103-05A-AL-PCM is ideal for applications where space is limited and thermal performance is critical. It works well in power electronics, telecom equipment, automotive systems, and industrial controls. The material maintains performance across a temperature range of -30°C to +125°C, making it suitable for a wide range of operating conditions.

The pad is 0.127 mm thick, lightweight, and easy to handle. Its aluminum backing adds mechanical stability, while the PCM layer ensures consistent thermal contact over time. It also offers high electrical insulation, with a volume resistivity of 2 × 10¹³ ohm-cm and a dielectric constant of 3.

By absorbing and releasing heat during phase transitions, GCSP-103-05A-AL-PCM helps maintain stable temperatures and protects components from thermal stress. It extends the life of electronic devices and ensures reliable performance under load.

Choose GCSP-103-05A-AL-PCM for efficient, repeatable thermal management in your next design. It’s a smart solution for engineers who need high thermal performance in a compact, easy-to-use format.
