Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

The filament requires a source holder compatible with F3 geometry and 4-wire 0.030 in diameter construction. The operating temperature of 1800°C and electrical load of 4V, 77A, 308W impose specific power supply and source assembly matching requirements.

Geometry and Holder Compatibility: The F3 geometry and 4-wire x 0.030 in diameter configuration must be verified against the evaporation source holder to ensure proper fit.
Electrical Matching: Voltage, current, and power ratings of 4V, 77A, and 308W respectively must be matched to the deposition power supply and source assembly.
Thermal Operating Limit: The rated operating temperature of 1800°C defines the upper bound for thermal evaporation configuration selection.

FAQ

What are the electrical and thermal specifications of the Atomfair F3 tungsten coil thermal filament?

The filament is rated for 4 V drive voltage, 77 A current, 308 W power, and an operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly used in the deposition system.

What is the wire configuration and physical geometry of the Atomfair F3 tungsten coil filament?

The filament uses 4 wires each 0.030 inches in diameter, arranged in an F3 reference geometry with 6 coils, 5 inches in length, and an inner diameter of 2 in-3/16 in. This geometry must be confirmed for fit with the evaporation source holder before purchase.

What package quantities are available for the Atomfair F3 tungsten coil filament?

The filament is offered in packages of 5 pieces or 10 pieces. The package size does not affect the electrical or thermal specifications; it only determines the quantity supplied for inventory and consumption planning.

Assessment

Technical evaluation of the Atomfair Tungsten Coil Thermal Filament (AF-TCF3-4W030) confirms a well-specified thermal evaporation source with defined electrical and dimensional parameters, but requires careful matching to power supply and holder for reliable operation.

Positive

Precise electrical and thermal ratings: The filament is rated at 4V, 77A, 308W, and 1800°C, enabling accurate matching to dedicated power supplies and thermal evaporation source assemblies for reproducible deposition.
Complete dimensional specifications: The filament is supplied with defined F3 geometry, wire count (4 wires x 0.030 in diameter), coil length (5 in), and inner diameter (2 in-3/16 in), allowing dimensional verification against source holder specifications before procurement.

Trade-offs

Exact electrical matching needed: The filament's voltage, current, and power ratings (4V, 77A, 308W) must be matched to the evaporation power supply; improper matching may lead to inefficient heating or filament failure.
Holder fit must be confirmed: The F3 geometry, wire count, and diameter (4 wires x 0.030 in) are specific; users must verify mechanical compatibility with their source holder before purchase.
