This filament requires a compatible vacuum deposition source holder that accepts the F15 geometry and a power supply capable of delivering 9.66 V, 85 A, and 821 W. The wire count and diameter must be matched to the source assembly to ensure proper electrical contact and thermal performance.

Geometry Fit: Confirm the filament geometry reference F15 matches the holder fit before purchase.
Electrical Matching: Match the voltage, current, and power requirements to the evaporation power supply and source assembly.
Package Quantity Selection: Select the required package quantity based on the number of coils needed for the deposition run.
Operating Temperature Reference: Use the rated operating temperature of 1800 °C as a reference for thermal evaporation configuration selection.

FAQ

How does the three-wire 0.040-inch diameter construction affect the electrical performance of this F15 tungsten coil filament compared to single-wire alternatives?

The three-wire construction reduces overall resistance, allowing higher current (85 A) at lower voltage (9.66 V) to achieve 821 W power and 1800 °C operating temperature. This configuration provides a larger evaporation surface area and more uniform heating for thermal deposition processes.

What power supply and source holder specifications are required to use this F15 tungsten coil filament?

The filament requires a power supply capable of delivering at least 9.66 V and 85 A continuously. The source holder must accommodate the F15 geometry: overall coil length of 5 inches and inner diameter ranging from 2 1/4 inches to 1/2 inch. Confirm mechanical fit before ordering.

What are the recommended handling and storage conditions for tungsten coil thermal filaments to maintain performance?

Store in a dry, inert environment to prevent tungsten oxidation. Handle with clean gloves to avoid oil or particulate contamination that could compromise vacuum deposition purity. Avoid mechanical deformation of the coil geometry as it may alter electrical characteristics and source alignment.

Assessment

This tungsten coil thermal filament with F15 geometry and 3 wires of 0.040 in diameter is specified for 1800°C thermal evaporation, with defined electrical ratings of 9.66 V, 85 A, and 821 W. It is available in 5-piece or 10-piece packages, requiring careful validation of holder fit and power supply compatibility.

Positive

Precise electrical specification for source matching: Rated voltage of 9.66 V, current of 85 A, and power of 821 W enable accurate matching with evaporation power supplies, reducing trial-and-error in system integration.
Defined operating temperature reference: Rated for 1800°C operation provides a reliable thermal profile for vacuum deposition processes, supporting consistent evaporation rates.

Trade-offs

Requires holder fit and geometry verification: The F15 geometry and dimensions (5 in L x 2 1/4 in-1/2 in ID) must be confirmed against the evaporation source holder to ensure mechanical compatibility before purchase.
Electrical load matching critical: The specified 9.66 V and 85 A require a power supply that can deliver precisely these values; deviations may cause suboptimal performance or filament damage.
