This filament requires exact electrical and geometric matching to the evaporation source holder and power supply. Operating temperature must not exceed 1800 °C to prevent material degradation.

Electrical Compatibility: Verify that the power supply delivers exactly 5.6 V, 83 A, and 465 W to match the filament's specified electrical load.
Geometry Fit: Confirm that the F5 geometry with 3 wires x 0.040 in diameter, 10 coils, 5 in length, and 2 in-1/4 in inner diameter fits the evaporation source holder.
Operating Temperature Limit: Do not exceed the rated operating temperature of 1800 °C during thermal evaporation to avoid filament failure.
Vacuum Environment Requirement: The filament is intended for use in vacuum deposition systems to prevent oxidation at high operating temperatures.

FAQ

What electrical specifications must be matched when integrating the F5 tungsten coil filament into a thermal evaporation system?

The F5 tungsten coil filament requires 5.6 V, 83 A, and 465 W, with a rated operating temperature of 1800 °C. These values must be confirmed against the evaporation power supply and source assembly to ensure proper operation and avoid overloading.

What are the physical dimensions and geometry of the F5 tungsten coil filament, and how do they affect compatibility with source holders?

The filament features F5 geometry with 3 wires of 0.040 in diameter, formed into 10 coils with a length of 5 inches and an inner diameter of 2-1/4 inches. These dimensions must match the evaporation source holder to ensure secure mounting and consistent deposition.

Why does the F5 tungsten coil filament use a 3-wire x 0.040 in diameter construction?

The 3-wire construction with 0.040 in diameter provides a defined geometry for thermal filament evaporation, balancing mechanical stability and electrical resistance to achieve the specified 1800 °C operating temperature and 465 W power rating. This configuration is selected to match common vacuum deposition source assemblies.

Assessment

This tungsten coil thermal filament with F5 geometry and 3 wires x 0.040 in diameter is specified for 1800 °C operation at 5.6 V, 83 A, and 465 W, making it suitable for thermal evaporation in vacuum deposition systems that require this exact source geometry and electrical loading.

Positive

Defined geometry and electrical spec: The F5 geometry with 3 wires x 0.040 in diameter and electrical ratings of 5.6 V, 83 A, 465 W enable precise matching to evaporation source holders and power supplies in thermal deposition systems.
High-temperature tungsten construction: Rated for 1800 °C operation, the tungsten filament provides a stable and repeatable thermal source for vacuum evaporation of materials requiring high-temperature heating.

Trade-offs

Requires exact electrical matching: The filament's voltage, current, and power specifications must be matched to the evaporation power supply; improper matching can lead to insufficient heating, damage, or suboptimal deposition conditions.
Geometry-dependent holder compatibility: The F5 reference geometry and 3-wire design require confirmation of fit with the source holder before purchase, limiting use to systems that accept this specific filament configuration.
