Tungsten Coil Thermal Filament F9 2×0.040 in ATOMFAIR®

Tungsten Coil Thermal Filament, F9 Geometry, 2 Wires x 0.040 in Diameter

Product Type: Thermal filament tungsten coil

Research-grade laboratory product

Product Overview

Tungsten Coil Thermal Filament, F9 Geometry, 2 Wires x 0.040 in Diameter is a tungsten thermal evaporation filament specified for 1800 °C operation, 6.66 V drive voltage, 65 A current and 433 W power. The 2 Wires x 0.040 in Diameter construction and 5 pcs/package and 10 pcs/package; 8 coils, 5 in L x 2 in-5/16 in ID format support selection for vacuum deposition source assemblies that require a defined tungsten filament geometry.

The item is intended for thermal filament evaporation workflows where wire count, wire diameter, source geometry and electrical loading must be matched before purchase. Use the listed geometry reference and electrical values to confirm fit with the evaporation source holder and power supply configuration.

This tungsten coil thermal filament must be matched to the specific geometry and electrical requirements of the evaporation source assembly. Selection without verification of holder fit and power supply compatibility may result in improper operation or damage.

Geometry and holder fit verification: Confirm that the F9 geometry, wire diameter, and coil dimensions are compatible with the evaporation source holder and that the required package quantity is selected.
Electrical parameter matching: Verify that the voltage (6.66 V), current (65 A), and power (433 W) ratings correspond to the output capabilities of the deposition power supply.

FAQ

What are the rated voltage, current, power, and operating temperature of the Atomfair F9 tungsten coil thermal filament?

The Atomfair F9 tungsten coil thermal filament is rated at 6.66 V, 65 A, 433 W, and an operating temperature of 1800 °C as specified in the technical specifications. These values must be matched to the evaporation power supply and source assembly during procurement.

What are the physical dimensions and geometry of the Atomfair F9 tungsten coil filament?

The filament features F9 geometry with 8 coils, a length of 5 inches, and an inner diameter of 2 in-5/16 in. It is constructed with 2 wires each 0.040 in diameter, which defines the wire count and diameter for thermal evaporation source compatibility.

What package sizes are available for the Atomfair F9 tungsten coil thermal filament?

The Atomfair F9 tungsten coil thermal filament is available in packages of 5 pieces or 10 pieces per package. Both packages contain the same F9 geometry filament with identical electrical and dimensional specifications; selection depends on expected usage volume.

Assessment

This F9 tungsten coil thermal filament is specified for 1800 °C evaporation with 6.66 V, 65 A, and 433 W electrical loading, allowing buyers to match source geometry and power supply requirements before deployment. The 2 Wires x 0.040 in diameter construction and 8-coil, 5 in L x 2 in-5/16 in ID format support vacuum deposition source assemblies requiring a defined tungsten filament geometry.

Positive

Defined electrical operating point: The 6.66 V, 65 A, and 433 W specification provides a clear reference for matching the filament to an evaporation power supply and source assembly during procurement review.
Specified geometry for source fit: The F9 reference geometry, 2 Wires x 0.040 in diameter construction, and 8-coil, 5 in L x 2 in-5/16 in ID format support selection for vacuum deposition source assemblies that require a defined tungsten filament geometry.

Trade-offs

Pre-purchase compatibility confirmation required: The filament geometry reference F9, holder fit, and electrical loading must be confirmed against the evaporation source holder and power supply configuration before purchase.
Application-specific selection constraints: This filament is intended for thermal filament evaporation workflows where wire count, wire diameter, source geometry, and electrical loading must be matched before use; incorrect matching can affect deposition system performance.
