Small Aluminium Heat Sink for TO-220 Package
[Aluminium Heat Sink] Small Aluminium Heat Sink for TO-220 Package The Small Aluminium Heat Sink for TO-220 Package is a compact passive cooling component designed for TO-220 package transistors, voltage regulators, MOSFETs, and other low-power semiconductor devices. It helps transfer heat away from the electronic component and dissipate it into the surrounding air, helping maintain a safer operating temperature. A matching product listing confirms that this heatsink is intended for low-power dissipation and includes a mounting hole for securing a transistor or voltage regulator. Its compact size makes it particularly useful where PCB space is limited. The heatsink is made from aluminium and has a 1mm material thickness, with overall dimensions of 15 × 9 × 19mm. ⭐ Key Features Designed for TO-220 package components Made from aluminium Compact and lightweight construction Suitable for low-power heat dissipation Helps reduce semiconductor operating temperature Mounting hole for securing compatible components Suitable for transistors, voltage regulators and similar devices Easy to install on electronic components Ideal for PCB and DIY electronics projects 📋 Technical Specifications Product Type: Aluminium Heat Sink Application: TO-220 Package Material: Aluminium Length: 15mm Width: 9mm Height: 19mm Thickness: 1mm Dimensions: 15 × 9 × 19mm Weight: Approximately 1g Mounting: Screw Mount Heat Dissipation: Passive / Natural Convection Application Type: Low-Power Semiconductor Cooling The dimensions and approximately 1g weight are listed by the corresponding product listing. 🔧 Applications TO-220 Transistors Voltage Regulators MOSFETs Power Transistors Linear Regulators Small Power Supply Circuits Arduino Projects DIY Electronics PCB Projects Embedded Electronics General Semiconductor Cooling 🛠️ Installation Place the heatsink against the heat-producing surface of the compatible TO-220 component and secure it through the mounting hole using an appropriate screw and nut. For improved thermal transfer, a suitable thermal interface material or thermal compound can be used between the component and heatsink where appropriate. Ensure that the heatsink does not accidentally create an electrical short between component terminals or other PCB traces. 📦 Package Includes 1 × Small Aluminium Heat Sink for TO-220 Package ⚠️ Precautions Use only with components that are mechanically compatible with the heatsink. Ensure the heatsink is securely mounted. Check for possible electrical contact between the heatsink and component terminals. Use thermal compound or an appropriate thermal interface where required. This is intended for low-power heat dissipation; higher-power applications may require a larger heatsink or forced-air cooling.
