This filament must be operated within specified electrical limits (2.69 V, 80 A, 215 W) and at or below 1800 °C. Use only in a vacuum deposition system with a compatible source holder and power supply.

  • Electrical Limits: Operate the filament only within the rated voltage of 2.69 V, current of 80 A, and power of 215 W.
  • Temperature Limit: Do not exceed the maximum operating temperature of 1800 °C to prevent filament degradation.
  • Atmosphere Requirement: Use the filament exclusively in a vacuum deposition system to prevent oxidation at high temperature.
  • Geometry Compatibility: Verify that the source holder accommodates the P4 geometry with 4 wires of 0.030 in diameter before installation.

Install and operate the tungsten point source filament safely by following these steps. Ensure proper electrical matching and vacuum environment to prevent damage or injury.

Required Equipment: Vacuum deposition system with compatible source holder, Power supply capable of 2.69 V, 80 A, 215 W

  1. Inspect filament
    Inspect the filament for any visible damage, deformation, or contamination before installation.
  2. Install filament
    Install the filament into the source holder, ensuring the P4 geometry aligns correctly with the holder contacts.
  3. Set power supply
    Set the power supply to the rated voltage of 2.69 V and current limit of 80 A before connecting the filament.
  4. Evacuate chamber
    Evacuate the deposition chamber to the required vacuum level before applying power to the filament.
  5. Apply power
    Apply power gradually and monitor the filament current to ensure it does not exceed 80 A.
  6. Cool down
    Allow the filament to cool completely before venting the chamber or handling the assembly.

What are the exact electrical requirements for operating the Atomfair Tungsten Point Source Filament (AF-PSP4-4W030) at its rated 1800 °C?

The filament requires a drive voltage of 2.69 V, a current of 80 A, and a power of 215 W to operate at the specified 1800 °C. These values must be matched to the evaporation power supply and source assembly used in the deposition system to ensure proper thermal performance.

How do I verify that the P4 geometry filament will fit my existing thermal evaporation source holder?

The filament has a P4 reference geometry with 4 wires of 0.030 in diameter and overall dimensions of 5 in L x 1/2 in H-1 in. Before purchase, confirm that your source holder accommodates this geometry and that the wire count and diameter match your assembly requirements. The product description explicitly states that holder fit must be verified before quotation.

P4-geometry tungsten point source filament with 4 wires x 0.030 in diameter is rated for 1800 °C operation at 2.69 V, 80 A, and 215 W, giving a defined electrical and thermal reference for vacuum thermal evaporation source matching; package quantities of 5 or 10 pieces are selectable.

Positive

  • Defined P4 multi-wire geometry: The 4 wires x 0.030 in diameter construction with P4 reference geometry provides a specified filament form factor for thermal evaporation source assemblies.
  • Documented electrical and thermal ratings: The specified 2.69 V, 80 A, 215 W, and 1800 °C operating point allows direct matching to deposition system power supplies and source configurations.

Trade-offs

  • Holder fit must be verified before purchase: The P4 geometry reference, holder fit, and required package quantity must be confirmed before quotation, so compatibility with the source assembly is not automatic.
  • Power supply and source assembly dependency: Voltage, current, and power requirements must be matched to the evaporation power supply and source assembly used in the deposition system, making this selection dependent on existing system infrastructure.
