Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

This tungsten filament requires precise electrical matching to the evaporation power supply and source assembly. The F5 geometry must be confirmed for holder fit before installation.

Electrical matching: The filament must be driven at 6.9 V, 37 A, and 255 W to achieve the rated 1800 °C operating temperature.
Geometry confirmation: The F5 geometry reference and 1 Wire x 0.040 in diameter must be verified against the source holder dimensions.
Package selection: The package quantity (5 or 10 pieces) should be selected based on the intended deposition runs.
Vacuum environment: The filament is designed for use in vacuum deposition systems and requires appropriate chamber conditions.
Power supply compatibility: The power supply must be capable of delivering the specified current and voltage without exceeding the filament's rated power.

FAQ

What voltage, current, and power are required to operate the Atomfair F5 tungsten coil thermal filament at its rated temperature?

The Atomfair AF-TCF5-1W040 tungsten coil filament requires 6.9 V, 37 A, and 255 W to operate at its rated temperature of 1800 °C. These electrical specifications must be matched to the evaporation power supply and source assembly used in the deposition system.

What physical dimensions must a thermal evaporation source holder accommodate to use the Atomfair F5 tungsten coil filament?

The F5 geometry filament consists of 10 coils with a length of 5 inches and an inner diameter of 2-1/4 inches, using a single 0.040-inch diameter wire. The source holder must fit this coil geometry and support the electrical connections for 6.9 V and 37 A.

Assessment

This tungsten thermal evaporation filament with F5 geometry and 1 wire x 0.040 in diameter is specified for 1800°C operation at 6.9 V, 37 A, and 255 W, suitable for vacuum deposition systems requiring a defined tungsten coil geometry.

Positive

Defined electrical parameters: Specified voltage (6.9 V), current (37 A) and power (255 W) enable precise matching to evaporation power supplies and source assemblies.
High-temperature 1800°C operation: Rated operating temperature of 1800°C provides a reference point for thermal evaporation of high-melting-point materials in vacuum deposition.

Trade-offs

Requires precise holder fit confirmation: The F5 geometry must be verified against the evaporation source holder before purchase; incompatible holders will not accept this filament.
Electrical matching mandatory: Voltage, current and power ratings must be matched to the power supply and source assembly; off-specification operation may cause failure or inconsistent deposition.
