Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

This tungsten point source filament is designed for thermal evaporation in vacuum deposition systems. Proper selection and electrical matching are required to ensure safe and effective operation.

Geometry Compatibility: Confirm the filament geometry reference P4 matches the evaporation source holder before purchase.
Electrical Matching: Verify that the power supply can deliver the required voltage and current limits specified for the filament.
Thermal Rating: Operate the filament only within its rated temperature of 1800 °C to prevent material degradation or failure.

FAQ

What voltage, current, and power are required to operate this tungsten point source filament at its rated temperature?

The filament requires 3.2 V, 51 A, and 163 W to reach its rated operating temperature of 1800 °C. These electrical specifications must be matched by the evaporation power supply and source assembly.

What is the wire configuration of this P4 tungsten filament?

The filament has 3 wires, each with a diameter of 0.025 in. This construction is specified for thermal evaporation source assemblies requiring a defined tungsten filament geometry.

What are the physical dimensions and package options for this filament?

The filament has a length of 5 in and a height of 1/2 in. It is available in packages of 5 pieces or 10 pieces per package.

Assessment

This tungsten point source filament with P4 geometry and 3-wire 0.025 in diameter construction is rated for 1800°C operation at 3.2V, 51A, and 163W, making it suitable for thermal evaporation in vacuum deposition systems where precise electrical and dimensional matching is required.

Positive

High-temperature tungsten construction: Rated operating temperature of 1800°C enables thermal evaporation of high-melting-point materials in vacuum deposition processes.
Defined electrical parameters: Specified 3.2V, 51A, and 163W allow direct cross-checking with the evaporation power supply and source assembly before procurement, reducing integration risk.

Trade-offs

Holder fit verification required: The fixed P4 geometry and 3-wire x 0.025 in diameter configuration must be confirmed compatible with the specific evaporation source holder and feedthrough assembly before use.
Temperature-dependent environment constraints: Operation at 1800°C requires a stable vacuum environment and adequate thermal management to prevent oxidation or premature filament degradation.
