Tungsten Coil Thermal Filament, F7 Geometry, 4 Wires x 0.030 in Diameter requires confirmation of geometry, holder fit, and power supply matching before use. Operate only in a vacuum deposition source assembly that accepts the specified tungsten filament geometry.

  • Geometry and holder compatibility: Confirm the F7 geometry reference and holder fit before installation.
  • Power supply matching: Match the voltage, current, and power requirements to the evaporation power supply and source assembly used in the deposition system.
  • Deposition source compatibility: Use the filament only in vacuum deposition source assemblies that require a defined tungsten filament geometry.

Confirm F7 geometry, holder fit, package quantity, and power supply electrical matching before installation. Use these checks during procurement review for vacuum deposition source assemblies.

Required Equipment: Evaporation power supply, Vacuum deposition source assembly

  1. Confirm F7 geometry reference
    Confirm the F7 geometry reference before quotation.
  2. Verify holder fit
    Verify the filament holder fit for the intended evaporation source assembly.
  3. Confirm package quantity
    Confirm the required package quantity before quotation.
  4. Match power supply requirements
    Match the voltage, current, and power requirements to the evaporation power supply and source assembly used in the deposition system.

How do the electrical specifications (10.31 V, 65 A, 670 W) of the F7 tungsten coil filament influence its selection for a specific thermal evaporation process?

The filament is rated for 1800 °C operation at 10.31 V, 65 A, and 670 W. Matching these values to the evaporation power supply ensures stable heating and prevents overloading. The 4-wire × 0.030 in diameter construction determines the resistance, so the voltage-current relationship must align with the source assembly design to achieve the required evaporation rate.

What physical dimensions and geometry features of the F7 tungsten coil filament must be verified for proper installation in a thermal evaporation source?

The filament uses F7 geometry with 14 coils, a length of 5 in, and an inner diameter of 2 in-3/8 in. The 4-wire × 0.030 in construction must fit the source holder’s terminal spacing and coil pocket. Confirming these dimensions against the evaporation source assembly is required before purchase to ensure electrical contact and uniform heating.

What operational considerations are required when using the F7 tungsten coil filament at its rated 1800 °C operating temperature?

At 1800 °C, the filament must be operated in a vacuum environment to prevent oxidation and maintain stable evaporation. The power supply must deliver 670 W continuously. Adequate cooling of the source assembly and thermal shielding may be necessary to protect adjacent components from radiant heat during deposition runs.

The F7 geometry tungsten coil filament with 4 wires of 0.030 in diameter is specified for 1800 °C thermal evaporation, requiring a 10.31 V, 65 A, 670 W power supply, making it suitable for vacuum deposition systems where precise electrical and geometric matching is critical.

Positive

  • Defined electrical and thermal specs: Rated at 10.31 V, 65 A, 670 W, and 1800 °C, the filament provides a clear reference for matching with 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 select quantities based on deposition run frequency and inventory management needs.

Trade-offs

  • Requires precise electrical matching: The filament's voltage, current, and power ratings must be exactly matched to the evaporation power supply and source assembly; mismatched electrical loading can cause suboptimal deposition or filament failure.
  • Geometry-dependent holder fit: The F7 geometry and 5 in L x 2 in-3/8 in ID dimensions require confirmation of compatibility with the specific evaporation source holder, as physical fit is not universal across deposition systems.
