DOWSIL™ 340 Heat Sink Compound
Thermal paste White, non-flowing, thick mixture with good thermal conductivity
Designed for thermal connection of electrical devices and PCB assemblies with radiators
Application:
- Radiators
- processors and electronic systems
- PCB assemblies
- aviation
- starting and charging batteries
- boards and components
- connectors, wiring harnesses
- thermal paste for cold stores
Features and benefits:
- single-component
- not flowing
- does not require heating or hardening
- increases reliability by moving heat away from electrical circuit components
Benefits of using
System components are continually designed for higher performance.
Especially in the consumer device space, there is also a continuing trend toward smaller, more compact designs. The combination of these factors usually means that more heat is generated in the device. Thermal management of PCB system assemblies is a primary concern for design engineers.
A cooler unit allows for more efficient operation and improved reliability throughout the life of the unit. As such, heat transfer compounds play an integral role here.
Thermally conductive materials act as a thermal "bridge" removing heat from the heat source (device) to the environment via a heat transfer medium (i.e., heat sink). These materials have properties such as low thermal resistance, high thermal conductivity, and can achieve a thin bond line thickness (BLT), which can help improve heat transfer away from the device.

Let customers speak for us
Produkt zgodny z opisem. Polecam
Świetny smar do mechanizmów precyzyjnych. Smaruję nim mechanikę magnetofonów, magnetowidów itp. Nie działa negatywnie na elementy gumowe jak też plastikowe. Jest dość rzadki i nie stwarza oporu dla precyzyjnych urządzeń. Świetnie je wycisza. Jest jeszcze jeden smar YM103 ale dostępny tyko w 1 kg puszkach. On jest nieco gęstszy.
Wszystko sprawnie , szybko i bez problemu . Polecam !!!
Szybka przesyłka; dobra dostępność środków, które trudno kupić gdzie indziej. Profesjonaliści.
Sam olej doskonały do hydromoddingu zegarków: rzadki, nie ma tendencji do spieniania się.
