What are the electrical requirements for the P3 tungsten point source filament and how do they affect thermal evaporation performance?

The filament requires 2.26 V, 50 A, and 113 W to operate at its rated 1800 °C. These values must be matched to the evaporation power supply to achieve the specified temperature, which directly influences deposition rate and film quality. The product description lists these as defined reference points for configuration selection.

Will the P3 geometry filament fit my existing evaporation source holder?

The filament has a P3 reference geometry with dimensions 3-1/2 in L x 5/8 in x 1/2 in d and a 3-wire x 0.025 in diameter construction. Users must confirm holder fit and geometry reference before purchase, as stated in the selection notes. The package size (5 or 10 pcs) does not affect physical fit.

Assessment

The Tungsten Point Source Filament with P3 geometry and 3 wires of 0.025 in diameter is specified for 1800 °C operation at 2.26 V, 50 A, and 113 W, making it suitable for thermal evaporation in vacuum deposition systems where precise electrical and geometric matching is required.

Positive

Defined electrical and thermal specs: Rated at 2.26 V, 50 A, 113 W, and 1800 °C, the filament provides clear electrical and thermal parameters for direct matching to power supplies and source assemblies in thermal evaporation workflows.
Multiple package size options: Available in 5 pcs/package and 10 pcs/package, allowing users to select the quantity that matches their deposition run frequency and inventory needs without over-ordering.

Trade-offs

Geometry-specific holder fit required: The P3 geometry and 3-1/2 in L x 5/8 in x 1/2 in d dimensions must be verified against the evaporation source holder before purchase to ensure mechanical compatibility.
Fixed electrical loading constraints: The specified 2.26 V, 50 A, and 113 W values require the evaporation power supply to deliver these exact parameters, limiting flexibility for systems with different output capabilities.
