This filament requires a vacuum environment for thermal evaporation and must be matched to a compatible holder and power supply. Operating at 1800°C with 136 W power, the filament geometry and electrical ratings must be confirmed before integration into the deposition system.

Vacuum Environment Requirement: The filament is designed for use in vacuum deposition source assemblies only.
Holder and Power Supply Compatibility: Confirm the P2 geometry holder fit and match voltage, current, and power requirements to the evaporation power supply.
Selection Prerequisite: Verify the filament geometry reference, holder fit, and package quantity before quotation to ensure system compatibility.

FAQ

What electrical specifications must be matched when integrating the P2 tungsten point source filament into a thermal evaporation system?

The filament requires a drive voltage of 2.83 V, current of 48 A, and power of 136 W at an operating temperature of 1800 °C. These values must be confirmed against the evaporation power supply and source assembly to ensure proper thermal evaporation performance.

What are the critical dimensional and geometric parameters for mounting the P2 tungsten filament in a vacuum deposition source holder?

The filament has a P2 geometry with 3 wires of 0.025 in diameter, and overall dimensions of 4.5 in L x 2 in x 0.5 in. The geometry reference P2 and holder fit must be confirmed before purchase to ensure mechanical compatibility with the source assembly.

Why is the 3-wire, 0.025-inch diameter construction specified for this point source filament?

The 3-wire construction with 0.025 in diameter provides a defined geometry for thermal evaporation source assemblies, balancing mechanical stability and electrical resistance to achieve the rated 136 W power at 1800 °C. This configuration is selected for applications requiring a consistent tungsten filament geometry.

Assessment

This tungsten point source filament with P2 geometry and 3 wires of 0.025 in diameter is specified for 1800°C operation at 2.83V, 48A, and 136W, enabling precise thermal evaporation in vacuum deposition systems. The available package sizes (5 or 10 pcs) allow procurement flexibility, but the specific geometry and electrical parameters require careful matching to the source holder and power supply.

Positive

Defined electrical parameters for matching: Voltage (2.83V), current (48A), and power (136W) are explicitly specified, enabling direct compatibility verification with existing evaporation power supplies and source assemblies.
High-temperature 1800°C operation: Rated for continuous operation at 1800°C, providing a reliable thermal evaporation source for high-melting-point materials in vacuum deposition.

Trade-offs

Geometry-specific compatibility required: The P2 geometry and 3-wire 0.025 in diameter configuration require the filament to be matched to the exact source holder design; incorrect fit may affect deposition uniformity or electrical contact.
Careful handling and installation needed: Tungsten filaments are brittle and susceptible to mechanical damage during handling and installation; proper mounting and alignment are critical to avoid premature failure at 1800°C.
