101 Products

A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components. Product regulations restrict sales to the listed jurisdictions/areas.

Surface fillers in one-time-use packets and jars come as two parts. The size listed is the combined total of the two parts.

Surface filler in a pen dispenses as a thin, ready-to-use liquid that fills in pitting and small gaps. It’s often used on circuit boards to fix components or to prototype new systems.

Volume resistivity and surface resistivity measure how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Made of indium, this foil is more thermally conductive than thermal interface materials (TIMs) made of plastic. By efficiently pulling heat away from components that produce heat, such as CPUs, this foil lets you use smaller forced cooling systems to extend battery life. It’s also softer and more ductile than paste and putty, covering surfaces better to minimize airflow gaps and increase heat flow. Unlike paste and grease, this foil won’t leach out from between surfaces over time, nor will it dry out and lose effectiveness. It’s clean, easy to install and reposition, and requires no surface preparation. Foil is corrosion resistant and doesn’t need special storage.

Foil with 48% tin has greater tensile and shear strength than foil without tin, but is less thermally and electrically conductive.

Protect computers, sensitive electronic components, lighting, injection molders, and HVAC systems from damage by routing heat away from them and toward a heat sink, where the heat can be dissipated. For best results, heat pipes should be soldered to heat sinks and other components. For small jobs and prototypes, however, they can be joined with thermal epoxy. Cooling capacity is the amount of heat that a heat pipe can carry.

Flat heat pipes, often called vapor chambers, can be embedded into your heat sink to spread heat uniformly across the base, helping the heat to dissipate faster.

Heat pipes with a grooved wick transfer heat better than those with a sintered wick, meaning they can carry more heat. They are not good, however, for applications that will require many bends in the pipe. Position them horizontally, since they do not work well against gravity.

Heat pipes with a sintered wick handle high fluctuations in temperature better than those with a grooved wick. They’re also best for applications that will require many bends in the pipe. Position them horizontally or vertically—they work well in both orientations.

Use optional heat pipe benders to create smooth, accurate bends in round heat pipe. These specially designed tools allow a smooth bending motion to reduce marks on your pipe, which ordinary pliers can often leave behind. All have graduation markings to prevent over bending, which can reduce the ability of your heat pipe to transfer heat. Every 45° bend in a heat pipe will reduce the cooling capacity of the heat pipe by about 2.5%. Place these tools on benches, vises, and workstations without scratching them—all have rubber mounting feet.
