This thermal filament requires confirmation of source holder geometry and package quantity before installation. Its electrical loading must be matched to the evaporation power supply and source assembly used in the deposition system.

Holder fit confirmation: Confirm the P3 geometry reference and holder fit against the evaporation source assembly before purchase.
Electrical matching: Match the filament's voltage, current, and power requirements to the evaporation power supply and source assembly used in the deposition system.

FAQ

What are the exact voltage, current, and power requirements for the P3 geometry tungsten point source filament, and how should these values be matched to a power supply?

The filament operates at 1.39 V, 79 A, and 110 W at 1800°C. These values must be matched to the evaporation power supply's output capabilities to ensure stable heating and avoid premature failure. The source explicitly states to match voltage, current and power requirements to the evaporation power supply and source assembly.

Does the P3 geometry tungsten filament require a specific holder or source assembly, or can it be used as a drop-in replacement for other point source filaments?

The filament is designed with a P3 geometry reference and a 3.5 in L x 5/8 in format, so it requires a holder that accommodates that specific geometry. The source advises to confirm the filament geometry reference P3, holder fit and required package quantity before quotation. It is not a universal drop-in; compatibility with the specific evaporation source holder must be verified.

What package size options are available for the P3 tungsten filament, and what factors should influence the choice between 5-piece and 10-piece packages?

The filament is offered in packages of 5 or 10 pieces, both containing the same 1-wire x 0.060 in diameter P3 geometry. The choice depends on the anticipated usage rate and the number of evaporation runs between replacements. Ordering the larger package reduces per-unit cost and ensures consistent geometry across multiple filament changes, which is critical for reproducible deposition results.

Assessment

This tungsten point source filament (P3 geometry, 1 wire x 0.060 in) is rated for 1800°C operation with specified electrical parameters of 1.39 V, 79 A, and 110 W, enabling precise thermal evaporation in vacuum deposition systems where source geometry and electrical loading must be matched.

Positive

High operating temperature 1800°C: Rated for continuous operation at 1800°C, supporting thermal evaporation of materials with high vaporization points.
Precisely specified electrical parameters: Exact voltage (1.39 V), current (79 A), and power (110 W) values allow straightforward matching with evaporation power supplies and source assemblies.

Trade-offs

Geometry and holder compatibility required: The P3 filament geometry and holder fit must be confirmed before purchase; not universally compatible with all evaporation source assemblies.
Fixed single-wire diameter constraint: The 0.060 in diameter single-wire construction is a fixed specification that may limit current-carrying capacity or evaporation rate flexibility for certain applications.
