20x20x6 mm Aluminum Heatsink – Effective Cooling for LED Drivers, Transistors and Miniature PCBs

Compact Silver Anodized Cooler with High Thermal Conductivity for Space-Constrained Applications

The 20×20×6 mm Silver Radiator / Aluminum Heatsink is a compact passive cooling solution made from aluminum, specifically designed to dissipate heat from small electronic components like ICs, MOSFETs, regulators, LEDs and similar devices. Its compact footprint and efficient thermal properties help maintain lower operating temperatures, improving performance and reliability in electronic circuits.

Key Features:

• Dimensions: approx 20 × 20 × 6 mm — ideal for small‑to‑medium‑sized components.

• Material: aluminum with a silver finish — lightweight and good thermal conductor.

• Passive Cooling: no fan — uses natural air convection for heat dispersion.

• Adhesive Mounting: often includes thermal adhesive tape for quick and secure attachment to components.

Typical Uses:
✔ Thermal management for power ICs and MOSFETs.
✔ Reducing heat buildup in voltage regulators and LED modules.
✔ Improving long‑term reliability in electronic assemblies.
✔ Compact electronics including 3D printer boards, embedded systems and sensor modules.

How it works:
A heatsink increases the surface area in contact with ambient air, allowing heat to move away from hot components through passive convection without requiring powered fans.
