This filament requires precise matching of geometry reference P1, wire count, and wire diameter to the evaporation source holder. Electrical parameters of 2.36 V, 65 A, and 153 W must be verified against the power supply's rated output before operation.

Geometry Compatibility: Confirm that the filament geometry reference P1 and the 3-wire, 0.030 in diameter construction match the source holder dimensions.
Electrical Matching: Verify that the evaporation power supply can deliver the required 2.36 V drive voltage, 65 A current, and 153 W power without exceeding its limits.
Package Quantity Selection: Select the package size (5 or 10 pieces) based on the anticipated number of deposition runs and replacement schedule.

FAQ

What electrical parameters must be matched when integrating this tungsten point source filament into an existing thermal evaporation system?

The filament is specified for 2.36 V, 65 A, and 153 W at 1800 °C operation. These values must be matched to the evaporation power supply and source assembly to ensure proper heating and avoid damage.

How does the P1 geometry reference and physical dimensions affect compatibility with evaporation source holders?

The P1 geometry is a defined reference; the filament dimensions are 5 in length and 3.5 in width (5 in L x 3 in-1/2 inh). Users must confirm holder fit against these dimensions and the P1 geometry before purchase to ensure proper installation.

What factors should be considered when choosing between the 5-piece and 10-piece package for this tungsten filament?

The filament is available in packages of 5 or 10 pieces. Selection depends on anticipated usage frequency, batch size, and the need for spare filaments during extended deposition runs. Both packages contain the same P1 geometry, 3-wire 0.030 in diameter construction.

Assessment

Evaluation of the 3-wire 0.030 in tungsten point source filament (P1 geometry) rated at 1800 °C, 2.36 V, 65 A and 153 W confirms it is purpose-built for thermal evaporation assemblies requiring a defined wire count and electrical loading.

Positive

Defined electrical envelope: The filament is specified at 2.36 V, 65 A and 153 W, enabling direct matching to evaporation power supplies before procurement.
Targeted tungsten geometry: The 3 wires x 0.030 in diameter P1 construction provides a defined source geometry for thermal filament evaporation workflows.

Trade-offs

Pre-purchase fit verification required: Holder fit and geometry reference P1 must be confirmed before quotation because the filament is specified for defined vacuum deposition source assemblies.
Power supply matching mandatory: Voltage, current and power requirements must be matched to the evaporation power supply and source assembly, as the filament operates at 65 A and 1800 °C.
