Compact 25 mm heat sink for small electronics

This 25 mm black heat sink is designed for hobbyists and engineers who need passive cooling on compact circuit boards. Its square footprint fits tight layouts where active fans cannot be used. The anodised finish aids heat dissipation without adding electrical conductivity.

Simple press-fit or adhesive mounting

Installation requires only thermal paste or a thermal pad and light pressure; no screws or brackets are included. The main difficulty is ensuring full contact on uneven component surfaces, which can leave air gaps and reduce cooling effectiveness.
