This tungsten filament must be operated within the specified electrical parameters of 2.95 V, 50 A, and 148 W to prevent damage. The filament geometry and holder fit must be verified before installation to ensure proper contact and alignment.

Electrical Matching: Match the voltage, current, and power requirements to the evaporation power supply and source assembly.
Holder Compatibility: Confirm the filament geometry reference P1 and holder fit before installation.
Temperature Limit: Operate the filament at or below the rated temperature of 1800 °C to avoid structural failure.

FAQ

What is the maximum operating temperature and corresponding electrical load for the AF-PSP1-3W025 tungsten point source filament?

The filament is rated for 1800 °C operation with a drive voltage of 2.95 V, current of 50 A, and power of 148 W. These values must be matched to the evaporation power supply to ensure proper thermal evaporation performance.

How do I confirm that the P1 geometry filament will fit my existing thermal evaporation source assembly?

Verify the filament geometry reference P1, overall dimensions of 5 in L x 1/2 in H, and the 3-wire x 0.025 in diameter construction against your source holder specifications. The electrical parameters (2.95 V, 50 A, 148 W) must also be compatible with your power supply configuration.

What package quantities are available for this tungsten point source filament and how should I select the right quantity?

The filament is offered in packages of 5 pcs or 10 pcs. Selection depends on your deposition run frequency and replacement schedule; the same geometry and electrical specs apply to both package sizes.

Assessment

This tungsten point source filament with P1 geometry and 3 wires of 0.025 in diameter is rated for 1800°C operation at 2.95 V, 50 A, and 148 W, requiring precise power supply matching and vacuum environment for reliable thermal evaporation.

Positive

Precise electrical specification for system matching: Rated at 2.95 V, 50 A, and 148 W, this filament enables direct compatibility verification with evaporation power supplies and source assemblies, reducing procurement errors.
High-temperature tungsten construction: Constructed from tungsten with 3 wires of 0.025 in diameter, the filament is rated for 1800 °C operation, providing a stable point source for thermal evaporation in vacuum deposition.

Trade-offs

Holder and geometry compatibility required: The P1 geometry and 5 in L x 1/2 in H dimensions necessitate confirmation of holder fit before purchase; mismatched holders may cause assembly failure.
Vacuum environment mandatory for operation: Designed for vacuum deposition source assemblies, this filament will oxidize rapidly if exposed to air at operating temperatures, requiring a controlled vacuum system.
