Out of stockAluminum Heat Sink for TO-220 Mosfet Transistor
[Aluminium Heat Sink] A heat sink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device. It allows the regulation of the device's temperature at an optimal level. In computers, heat sinks are use to cool central processing units or graphics processors. If heat dissipation ability of the component itself is insufficient to maintain it's temperature; then Heat sinks are use with high-power semiconductor devices. An Aluminum heatsink is the most widely used product for thermal solutions. Features: Excellent corrosion resistance Low weight Non-magnetic Easy to recycle Great addition to your hobby craft tool kit. Perfect Product for your safety and Lab supply. Good for many applications include industrial, laboratory, personal, and hobbies. Package includes This is the pack of 1 piece of 2cm x 1.5cm Aluminium heatsink for TO-220 Mosfet transistor

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.
Water Cooling Head Water Cooling Plate 40*40mm
[Aluminium Heat Sink] Liquid coolers excel at delivering cooling to concentrated heat sources such as Peltier Elements and for delivering cooled fluid into remote or compact locations where the cooling assembly itself cannot be located. The basic operation is simple: fluid flows in one tube, it is cooled, and then it flows out the other tube. An external pump is required, and typically small DC magnetic-drive pumps are used to minimize the amount of pump power (heat) that is imparted to the fluid. Applications: Computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling. Features: Heavy Aluminium build Internal flow channel extrusion forming Applicable to computer CPU water, industrial inverter driver, laser head cooling, industrial control cabinet cooling Package Includes: 1 x Water Cooling Head Water Cooling Plate 40*40mm

[Aluminium Heat Sink] Universal Aluminium Heat Sink Heat sinks are generally made of metals; and, aluminium is the most common metal used in the heat sink. We are aware of the fact that the thermal conductivity of each metal is different. The thermal conductivity of metal is proportional to the heat transfer in the heat sink. Thus, if the thermal conductivity of the metal increases, then the heat transferring capacity of the heat sink will also increase. The thermal conductivity of aluminium is 235 W/mK, it is the cheapest and most lightweight metal. Aluminium heat sinks are also called extruded heat sinks as they can be made using extrusion. Specification: No. of Blades 16 Mountable Size (mm) ~32 x ~11 Colour Silver Grey Blade Thickness (mm) 0.6mm Approx. Base Plate Thickness (mm) 1.5mm Approx.
