What electrical parameters must be matched when integrating the AF-TCF4-3W025 tungsten coil filament into a thermal evaporation system?

The filament requires 5.29 V, 48 A, and 254 W at an operating temperature of 1800 °C. These values must be confirmed against the evaporation power supply and source assembly to ensure proper operation.

Which filament geometry reference and holder configuration is required for the F4 tungsten coil?

The filament uses the F4 geometry reference with a 3-wire x 0.025 in diameter construction, 6 coils, and dimensions of 4 in length with an inner diameter ranging from 1/4 in to 1 3/4 in. The holder fit must match this geometry.

What are the physical dimensions of the F4 tungsten coil filament for installation planning?

The filament has 6 coils, a length of 4 inches, and an inner diameter ranging from 1/4 inch to 1 3/4 inch. These dimensions must be accommodated in the evaporation source holder.

Assessment

The Tungsten Coil Thermal Filament (F4 geometry, 3 wires × 0.025 in diameter) is specified for 1800 °C operation with a drive voltage of 5.29 V, 48 A current, and 254 W power, making it suitable for thermal evaporation in vacuum deposition systems where the wire count, diameter, and source geometry must be matched to the holder and power supply configuration.

Positive

Defined electrical and thermal specs: Rated voltage (5.29 V), current (48 A), power (254 W), and operating temperature (1800 °C) are explicitly stated, enabling direct matching to evaporation power supplies and source assemblies without ambiguity.
Standardized F4 geometry: The F4 geometry with 6 coils, 4 in L × 1 3/4 in–1/4 in ID format is precisely defined, ensuring compatibility with common filament holders and allowing reproducible placement in thermal deposition tools.

Trade-offs

Requires exact power supply match: The filament's electrical specifications (5.29 V, 48 A, 254 W) are fixed; any deviation in the installed power supply output or source assembly impedance requires recalibration or replacement to avoid underperformance or damage.
Fixed geometry limits retrofit flexibility: The filament's predefined dimensions (4 in length, 1 3/4 in–1/4 in ID, 6 coils) may not accommodate all custom or non-standard deposition source holders, necessitating verification of physical fit before procurement.
