A4988 Aluminum Heat Sink 9x9x5mm with Adhesive Tape

The A4988 Aluminum Heat Sink 9x9x5mm is a compact, high-efficiency cooling solution designed specifically for stepper motor driver ICs. Stepper drivers like the A4988 and DRV8825 generate significant heat during continuous operation in 3D printers and CNC machines. This lightweight aluminum heatsink effectively dissipates thermal energy, preventing driver overheating, thermal shutdown, and step-skipping issues to ensure smooth and precise motor control.

Featuring a pre-applied thermal conductive adhesive backing, this heatsink offers a hassle-free, peel-and-stick installation directly onto the driver chip. Its multi-fin design maximizes the surface area for optimal convective heat transfer, making it highly compatible with RAMPS 1.4, CNC shields, Creality motherboards, and various DIY microcontroller projects utilizing compact driver modules.

Features:

• Optimized Dimensions: 9x9x5mm footprint fits perfectly on standard A4988, DRV8825, and TMC-series stepper driver ICs without shorting adjacent pins.
• High-Grade Aluminum: Manufactured from premium aluminum alloy for excellent thermal conductivity and rapid heat dissipation.
• Pre-Applied Thermal Tape: Features a highly conductive thermal adhesive backing for secure, long-lasting attachment without needing external thermal glue.
• Multi-Fin Structure: Engineered with parallel cooling fins to maximize airflow and surface area contact.
• Ultra-Lightweight: Weighing only 0.8 grams, it adds virtually zero mechanical stress to your driver boards.
