Brand: ATOMFAIR®

This filament requires precise matching of geometry and electrical parameters to the evaporation source holder and power supply. The filament must be operated within its rated voltage, current, and power specifications to prevent damage and ensure proper deposition.

Geometry Compatibility: The F12 geometry with 3 wires x 0.030 in diameter must align with the holder dimensions to avoid improper contact or arcing.
Electrical Matching: The voltage of 3.82 V, current of 57 A, and power of 218 W must be supplied by the evaporation power supply without exceeding these values.
Temperature Limit: The operating temperature of 1800°C is the maximum; sustained operation above this may cause filament degradation or failure.
Package Selection: Choose the 5-pack or 10-pack based on the number of deposition runs required to avoid reordering delays.
Vacuum Environment: This filament is designed for use in vacuum deposition systems and must not be operated in ambient atmosphere to prevent oxidation.

FAQ

What voltage, current, and power ratings are specified for the Atomfair Tungsten Coil Thermal Filament F12?

The filament is rated for 3.82 V drive voltage, 57 A current, and 218 W power at an operating temperature of 1800 °C. These electrical specifications must be matched to the evaporation power supply and source assembly used in the deposition system.

How do I verify that the F12 geometry tungsten coil filament will fit my evaporation source holder?

The filament uses reference geometry F12 with dimensions of 5 coils, 1 in length, 1 in height, and 1/4 in inner diameter, constructed from 3 wires of 0.030 in diameter. Confirm that your source holder accommodates these physical dimensions and wire count before purchase.

Assessment

The F12 geometry tungsten coil thermal filament with 3 wires × 0.030 in diameter is specified for 1800 °C operation at 3.82 V, 57 A, and 218 W, making it suitable for vacuum thermal evaporation sources requiring a defined wire count and electrical loading. The 5-coil package format (1 in L × 1 in H × 1/4 in ID) must be matched to the source holder and power supply before purchase.

Positive

Defined electrical and thermal specs: Rated at 3.82 V, 57 A, 218 W, and 1800 °C operating temperature, enabling direct compatibility verification with existing evaporation power supplies and source assemblies.
Multi-wire geometry for uniform deposition: Three-wire × 0.030 in diameter construction in F12 geometry provides a stable, repeatable filament profile for consistent thermal evaporation in vacuum systems.

Trade-offs

Fixed geometry limits source compatibility: The F12 geometry and 5-coil package dimensions (1 in L × 1 in H × 1/4 in ID) require exact fit verification with the evaporation source holder; mismatched holders cannot be adapted without custom fabrication.
Electrical loading must be pre-matched: The 3.82 V, 57 A, 218 W specification demands a power supply capable of delivering these exact parameters; off-spec supplies risk underheating or filament damage during operation.
