Tungsten Coil Thermal Filament, F8 Geometry, 3 Wires x 0.040 in Diameter

Product Type: Thermal filament tungsten coil

Research-grade laboratory product

Product Overview

Tungsten Coil Thermal Filament, F8 Geometry, 3 Wires x 0.040 in Diameter is a tungsten thermal evaporation filament specified for 1800 °C operation, 4.61 V drive voltage, 87 A current and 401 W power. The 3 Wires x 0.040 in Diameter construction and 5 pcs/package and 10 pcs/package; 6 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.

What voltage, current, and power specifications must be matched when using the F8 tungsten coil filament?

The filament requires 4.61 V, 87 A, and 401 W at its rated 1800°C operating temperature. These values must be matched to the evaporation power supply and source assembly to ensure proper thermal evaporation performance.

What are the physical dimensions of the F8 geometry tungsten coil filament for holder compatibility?

The filament has a 3-wire x 0.040 in diameter construction with 6 coils, overall length 5 inches, and inner diameter of 2 in-5/16 in. Confirm that the evaporation source holder can accommodate these dimensions before purchase.

Assessment

The F8 geometry tungsten coil thermal filament with 3 wires x 0.040 in diameter is specified for 1800 °C operation at 4.61 V, 87 A, and 401 W, making it suitable for thermal evaporation sources in vacuum deposition systems where wire count, diameter, and electrical loading must be matched to the power supply and holder configuration.

Positive

Defined electrical and thermal specs: Rated at 4.61 V, 87 A, 401 W, and 1800 °C, the filament provides a clear reference for matching to evaporation power supplies and source assemblies, reducing procurement uncertainty.
Multiple package size options: Available in 5 pcs/package and 10 pcs/package configurations, allowing labs to select quantity based on usage frequency without overstocking.

Trade-offs

Geometry-specific holder fit required: The F8 geometry and 6-coil 5 in L x 2 in-5/16 in ID format require confirmation of compatibility with the evaporation source holder before purchase.
Electrical loading must be pre-matched: Voltage, current, and power values are fixed; the filament cannot be used with power supplies or source assemblies that do not match these exact electrical parameters.
