Description

Aluminum TO-220 / TO-3P High-Efficiency Thermal Cooler

Technical Specifications of Heat Sink Mini

• Material: Premium grade aluminum alloy for rapid thermal conductivity and dissipation.

• Compatibility: Specifically designed for TO-220, TO-3P, and TO-247 electronic package styles.

• Dimensions: Ultra-compact 25 x 15 x 11 mm profile for dense PCB layouts.

• Mounting: Features a pre-drilled M3 screw hole for secure component attachment.

• Finish: Professionally anodized black surface to improve radiative heat transfer efficiency.

• Weight: Featherlight 3.5g mass avoids putting mechanical stress on delicate solder joints.

• Thermal Flow: Optimized fin geometry promotes natural convection for passive cooling.

• Keyphrase Usage: This Heat Sink Mini offers a zero-noise solution for power transistors.

Usage and Component Installation

• First, apply a thin layer of thermal paste to the back of your IC.

• Next, align the component mounting hole with the M3 opening on the aluminum.

• Then, tighten an M3 screw to ensure maximum surface contact for conduction.

• Afterward, utilize the assembly in power supplies or motor driver circuits.

• Consequently, the Heat Sink Mini draws heat away from the sensitive silicon junction.

• Finally, ensure air flows freely around the fins to maximize convection cooling.

Advantages and Disadvantages of Heat Sink Mini

• Pros: Passive cooling requires no electrical power and operates with absolutely zero noise.

• Furthermore, the anodized finish provides a durable, corrosion-resistant layer for industrial use.

• Cons: Small surface area is insufficient for extremely high-wattage power dissipation tasks.

• Additionally, it requires physical space on the PCB which might interfere with nearby parts.

Precautions and Thermal Safety

• Warning: Use an insulating mica sheet if the component tab is electrically live.

• Avoid over-tightening the M3 screw to prevent cracking the ceramic IC casing.

• Do not touch the heat sink during operation as it may reach high temperatures.

What is Included in the Package

• 1x Heat Sink Mini (Black Anodized Aluminum TO-220 / TO-3P Type).

• Precision-drilled M3 mounting hole integrated into the lightweight aluminum body.
