This tungsten coil thermal filament is intended for vacuum deposition source assemblies and must be matched to the source holder and power supply configuration before use. The F8 geometry and electrical loading requirements must be confirmed against the evaporation system before operation.

  • Geometry and holder fit constraint: Confirm the F8 geometry reference and holder fit against the evaporation source assembly before use.
  • Electrical matching constraint: Match the filament's voltage, current, and power requirements to the evaporation power supply and source assembly.

Configure and install this tungsten coil filament only after source holder and power supply compatibility are confirmed. Operate the filament within its rated electrical and thermal envelope during vacuum deposition.

Required Equipment: Evaporation source holder, Evaporation power supply

  1. Confirm geometry compatibility
    Confirm the F8 geometry reference and holder fit against the evaporation source assembly.
  2. Verify power supply compatibility
    Verify that the power supply can deliver the filament's rated voltage, current, and power requirements.
  3. Install the filament
    Load the filament into the evaporation source holder after compatibility is confirmed.
  4. Apply power within ratings
    Energize the filament within its rated operating envelope during thermal evaporation.

What are the exact electrical specifications of the Atomfair F8 tungsten coil filament and how should they be matched to a power supply?

The filament requires 5.09 V, 74 A, and 377 W for operation at 1800 °C. These values must be matched to the evaporation power supply and source assembly to ensure proper thermal performance and avoid damage. The listed electrical loading is specific to the 4 wires x 0.030 in diameter construction and F8 geometry.

What are the physical dimensions of the F8 geometry filament and how do they ensure compatibility with thermal evaporation source holders?

The filament features 6 coils with a length of 5 inches and an inner diameter of 2 in-5/16 in, defined as F8 reference geometry. These dimensions, along with the 4-wire x 0.030 in diameter construction, must be confirmed against the evaporation source holder fit before purchase. The geometry directly affects mounting alignment and deposition uniformity in vacuum deposition assemblies.

What package quantities are available for the F8 tungsten coil filament and what factors should guide the selection between 5-piece and 10-piece packs?

The filament is offered in packages of 5 pieces or 10 pieces per pack. Selection depends on the required quantity for the deposition run frequency and inventory management in the laboratory. Both packages contain the same F8 geometry, 4 wires x 0.030 in diameter filament, so the choice is purely based on consumption rate and procurement cycle.

The F8 geometry tungsten coil thermal filament with 4 wires × 0.030 in diameter is specified for 1800 °C operation at 5.09 V, 74 A, and 377 W, making it suitable for thermal evaporation sources requiring a defined wire count and electrical loading. The 6-coil, 5 in L × 2 in-5/16 in ID format must be matched to the evaporation source holder and power supply before purchase.

Positive

  • Defined electrical and thermal specs: Rated at 5.09 V, 74 A, 377 W, and 1800 °C, the filament provides a clear reference for matching to evaporation power supplies and source assemblies, reducing trial-and-error during procurement.
  • Multiple package size options: Available in 5 pcs/package and 10 pcs/package, allowing labs to order quantities that match their deposition run frequency without overstocking.

Trade-offs

  • Geometry-specific holder fit required: The F8 geometry and 5 in L × 2 in-5/16 in ID format must be verified against the evaporation source holder; incompatible holders will require adapter modifications or alternative filament selection.
  • High current and power demand: The 74 A current and 377 W power requirement necessitate a compatible power supply and wiring infrastructure; labs with lower-rated supplies cannot operate this filament without upgrade.
