The filament must be matched to a power supply delivering 1.59 V, 84 A, and 134 W. It requires installation in a vacuum deposition system with a compatible P3 geometry holder.

Electrical Specification Matching: Confirm the power supply voltage, current, and power ratings match the filament's 1.59 V, 84 A, and 134 W specifications.
Geometry Compatibility: Verify the filament's P3 geometry and dimensions (3-1/2 in L x 5/8 in-1/2 in H) are compatible with the evaporation source holder.
Vacuum Environment Requirement: Operate the filament only within a high vacuum deposition system to prevent oxidation and ensure proper thermal evaporation.
Operating Temperature Limit: Do not exceed the rated operating temperature of 1800 °C to avoid filament degradation or failure.

FAQ

What are the exact electrical specifications for the P3 geometry tungsten point source filament with 4 wires x 0.030 in diameter?

The filament is specified for 1.59 V drive voltage, 84 A current, and 134 W power at an operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly before purchase to ensure proper thermal evaporation performance.

Does the P3 geometry filament fit standard thermal evaporation source holders, and what physical dimensions must be verified?

The filament has a P3 reference geometry with overall dimensions of 3-1/2 in L x 5/8 in-1/2 in H. Users must confirm holder fit and geometry reference P3 compatibility with their specific vacuum deposition source assembly before ordering, as the wire count and diameter are fixed at 4 wires x 0.030 in.

What handling or storage precautions are required for the tungsten point source filament before installation?

Assessment

This tungsten point source filament with P3 geometry and 4 wires of 0.030 in diameter is engineered for 1800°C thermal evaporation, requiring precise electrical matching to the power supply and careful holder fit verification due to its specific dimensions.

Positive

Rated 1800°C operating temperature: The filament is specified for 1800 °C, enabling thermal evaporation of high-melting-point materials in vacuum deposition systems.
Precise electrical specification: Voltage (1.59 V), current (84 A), and power (134 W) are provided, allowing direct verification of compatibility with the evaporation source power supply.

Trade-offs

Requires power supply matching: The filament's electrical parameters must be matched to the existing evaporation power supply, which may limit retrofitting into systems with different electrical ratings.
Fixed geometry and dimensional fit: The P3 geometry and 3-1/2 in L x 5/8 in-1/2 in H dimensions are specific, requiring verification of compatibility with the source holder before purchase.
