Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

This filament is rated for continuous operation at 1800°C with a maximum electrical load of 3.8 V, 51 A, and 194 W. It must be used only in vacuum deposition systems with a compatible P5 geometry holder and power supply configured to these limits.

Operating Temperature Limit: The filament must not exceed 1800°C to prevent structural degradation.
Electrical Limit: Drive voltage, current, and power must not exceed 3.8 V, 51 A, and 194 W respectively.
Holder Compatibility: Only use with evaporation source holders that accept P5 geometry filaments.
Vacuum Environment: This filament is intended for use in vacuum deposition systems; operation in ambient atmosphere is not supported.

FAQ

Why does the Atomfair AF-PSP5-3W025 tungsten point source filament use a 3-wire construction instead of a single wire?

The 3-wire × 0.025 in diameter geometry provides a defined source area and electrical resistance profile optimized for thermal evaporation at 1800 °C. The 3.8 V, 51 A, 194 W specification is matched to this multi-wire configuration to ensure uniform heating and consistent deposition rates.

What power supply and holder specifications are required to operate the Atomfair P5 tungsten filament?

The filament requires a power supply capable of delivering 3.8 V, 51 A, and 194 W. The P5 geometry (4 in L – 1/2 in × 1/2 in) must fit the evaporation source holder. Confirm mechanical fit and electrical ratings before integration.

How should I choose between the 5-piece and 10-piece package for the Atomfair P5 tungsten filament?

Select the package size based on anticipated usage frequency and replacement schedule. Both packages contain identical filaments; the 5-pack is suitable for low-volume or trial runs, while the 10-pack offers cost efficiency for routine deposition work. Always verify holder compatibility and geometry before ordering.

Assessment

The Tungsten Point Source Filament, P5 Geometry, 3 Wires x 0.025 in Diameter is a thermal evaporation filament rated for 1800 °C operation with defined electrical parameters (3.8 V, 51 A, 194 W), requiring precise matching to the power supply and source holder geometry before deployment.

Positive

Defined electrical and thermal specs: Rated at 3.8 V, 51 A, 194 W, and 1800 °C, the filament provides a clear reference for matching to evaporation power supplies and source assemblies, reducing trial-and-error during system integration.
Multiple package size options: Available in 5 pcs/package and 10 pcs/package configurations, allowing users to select a quantity that aligns with experimental throughput or replacement frequency without overstocking.

Trade-offs

Geometry-dependent holder fit: The P5 geometry and 4 in L -1/2 in x 1/2 in format require confirmation of compatibility with the specific evaporation source holder, as mismatched dimensions can prevent proper installation or electrical contact.
Fixed electrical loading constraints: Operation at 3.8 V, 51 A, and 194 W demands a power supply capable of delivering these exact parameters; deviations may lead to suboptimal evaporation rates or filament damage.
