Tungsten Point Source Filament P3 0.030 in ATOMFAIR®

Tungsten Point Source Filament, P3 Geometry, 3 Wires x 0.030 in Diameter

Product Type: Thermal filament point source

Research-grade laboratory product

Product Overview

Tungsten Point Source Filament, P3 Geometry, 3 Wires x 0.030 in Diameter is a tungsten thermal evaporation filament specified for 1800 °C operation, 1.94 V drive voltage, 64 A current and 124 W power. The 3 Wires x 0.030 in Diameter construction and 5 pcs/package and 10 pcs/package; 3-1/2 in L x 5/8 in-1/2 inh format support selection for vacuum deposition source assemblies that require a defined tungsten filament geometry.

The item is intended for thermal filament evaporation workflows where wire count, wire diameter, source geometry and electrical loading must be matched before purchase. Use the listed geometry reference and electrical values to confirm fit with the evaporation source holder and power supply configuration.

Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

This tungsten filament operates at 1800 °C with electrical limits of 1.94 V, 64 A, and 124 W. Exceeding these parameters may cause filament failure; ensure proper power supply matching and source holder fit before use.

Electrical Constraints: Do not exceed the rated voltage of 1.94 V, current of 64 A, or power of 124 W to prevent filament damage.
Thermal Constraint: Operating temperature must not exceed 1800 °C to avoid structural failure of the filament.
Mechanical Fit: Confirm the P3 geometry and source holder fit before installation to ensure proper electrical contact and alignment.
Package Selection: Select the appropriate package quantity (5 or 10 pcs) based on anticipated usage to avoid unnecessary waste.

FAQ

What are the electrical and thermal specifications for the Atomfair Tungsten Point Source Filament P3 geometry with 3 wires x 0.030 in diameter?

The filament is rated for 1800 °C operation with a drive voltage of 1.94 V, current of 64 A, and power of 124 W. These values must be matched to the evaporation power supply and source assembly before procurement to ensure proper thermal evaporation performance.

How do I confirm compatibility of the P3 geometry tungsten filament with my existing vacuum deposition source holder?

Compatibility depends on matching the P3 geometry reference, the 3-1/2 in L x 5/8 in-1/2 in overall format, and the 3-wire x 0.030 in diameter construction to the source holder dimensions. The product is offered in 5 pcs/package and 10 pcs/package quantities, and the geometry reference must be verified against the holder fit before ordering.

What package size options are available for this tungsten point source filament, and how does wire count affect evaporation uniformity?

The filament is available in 1 pack of 5 pieces or 1 pack of 10 pieces. The 3-wire construction with 0.030 in diameter per wire provides a defined source geometry for thermal filament evaporation, where wire count and diameter directly influence the evaporation rate and uniformity profile in vacuum deposition systems.

Assessment

This variable product is a P3-geometry tungsten point source filament constructed from three 0.030 in diameter wires and rated for 1800 °C operation at 1.94 V, 64 A, and 124 W. The package size variations of 5 or 10 pieces do not alter the electrical or thermal specification.

Positive

Rated 1800 °C tungsten filament: Tungsten construction with a 3-wire, 0.030 in diameter P3 geometry is rated for 1800 °C operation, providing a defined thermal reference point for thermal evaporation source configuration.
Specified electrical loading for source matching: The stated 1.94 V, 64 A, and 124 W electrical values allow buyers to verify compatibility with the evaporation power supply and source assembly before procurement.

Trade-offs

Holder fit must be confirmed before purchase: The selection notes require confirmation of the P3 geometry reference, holder fit, and package format with the evaporation source assembly before quotation.
Power supply parameters must be matched: Voltage, current, and power requirements must be matched to the evaporation power supply and source assembly, so operating compatibility depends on external infrastructure that the buyer must verify.
