FAQ

What electrical specifications must be matched when integrating the P6 tungsten point source filament into an existing evaporation power supply?

The filament requires a drive voltage of 1.94 V, a current of 42 A, and a power of 81 W. These values must be confirmed against the power supply's output capabilities and the source assembly's electrical path to ensure proper heating and avoid under- or over-power conditions.

What are the critical physical dimensions of the P6 geometry filament that determine compatibility with a thermal evaporation source holder?

The filament has a wire diameter of 0.040 in, a length of 3.5 in, and a loop size of 3/8 in. The P6 geometry reference must match the holder design; verify these dimensions against the source holder's filament mounting points before purchase.

What is the significance of the 1800 °C operating temperature rating for this tungsten point source filament?

The 1800 °C rating provides a defined reference point for thermal evaporation configuration selection, indicating the maximum sustained temperature the filament can reach during operation. This helps in matching the filament to materials with specific evaporation temperatures and ensures consistent deposition conditions.

Assessment

This Tungsten Point Source Filament (P6, 1 Wire x 0.040 in Diameter) is rated for 1800 °C operation with defined electrical parameters (1.94 V, 42 A, 81 W), making it suitable for thermal evaporation systems that require precise geometry and electrical matching.

Positive

Defined Electrical Specifications: The filament provides explicit voltage (1.94 V), current (42 A), and power (81 W) ratings, enabling direct matching with evaporation power supplies and source assemblies.
High-Temperature Tungsten Construction: Rated for 1800 °C operation, the tungsten filament supports thermal evaporation of materials requiring high source temperatures.

Trade-offs

Geometry and Holder Compatibility Required: The P6 geometry and dimensions (0.040 in diameter, 3.5 in length, 3/8 in loop) must be verified against the evaporation source holder; mismatch can prevent proper installation.
Electrical Loading Must Be Matched: The 1.94 V, 42 A, 81 W electrical profile must be within the range of the connected power supply to avoid underperformance or damage.
