This tungsten filament is rated for 1800 °C operation in a vacuum deposition environment. The electrical drive parameters (2.08 V, 73 A, 152 W) must be matched to the power supply to prevent damage.

Vacuum Requirement: The filament is intended for use only in vacuum deposition systems to avoid oxidation and ensure proper thermal evaporation.
Temperature Limit: Do not exceed the rated operating temperature of 1800 °C to prevent filament degradation or failure.
Electrical Matching: Confirm that the power supply delivers the specified 2.08 V, 73 A, and 152 W to avoid electrical overload.
Geometry Fit: Verify that the P1 geometry and 1 Wire x 0.060 in diameter match the source holder before installation.

FAQ

How does the 1 Wire x 0.060 in diameter construction affect the electrical performance and evaporation characteristics of this tungsten point source filament?

The single-wire, 0.060 in diameter geometry defines the filament's resistance and thermal profile, requiring 2.08 V, 73 A, and 152 W to reach its rated 1800 °C operating temperature. This configuration provides a localized point source for controlled thermal evaporation in vacuum deposition systems, with the P1 geometry ensuring consistent emission characteristics.

What parameters must be verified to ensure compatibility of this P1 geometry filament with an existing evaporation source holder and power supply?

Confirm that the source holder accepts the P1 geometry reference and the 5 in L x 1/2 in H filament dimensions. The power supply must be capable of delivering 2.08 V, 73 A, and 152 W, and the wire count (1 wire) and diameter (0.060 in) must match the assembly design. These specifications are explicitly listed for pre-purchase matching.

How should I choose between the 5 pcs/package and 10 pcs/package options for this tungsten point source filament?

Both package sizes contain identical filaments with the same P1 geometry, wire specification, and electrical ratings (2.08 V, 73 A, 152 W, 1800 °C). Selection depends on expected usage volume and replacement frequency; the 10 pcs/package option suits higher-throughput deposition schedules, while the 5 pcs/package is appropriate for lower-volume or pilot runs.

Assessment

The AF-PSP1-1W060 is a P1-geometry tungsten point source filament constructed as 1 wire x 0.060 in diameter, rated to 1800 °C and specified at 2.08 V, 73 A, and 152 W for thermal evaporation source matching.

Positive

Rated 1800 °C tungsten filament: The 1800 °C rated operating temperature provides a defined thermal reference point for configuring tungsten thermal evaporation sources.
Electrical specifications support source matching: The stated 2.08 V, 73 A, and 152 W ratings allow the filament to be matched against the evaporation power supply before procurement and installation.

Trade-offs

Holder fit must be confirmed: The P1 geometry reference and 5 in L x 1/2 in H dimensions require confirmation against the evaporation source holder before quotation, since fit is not implicit.
Power supply compatibility is mandatory: Voltage, current, and power requirements must be matched to the evaporation power supply and source assembly used in the deposition system to avoid improper operation.
