Filament geometry reference F4 and wire specification require verification against the source holder prior to use. Electrical parameters of 3.97 V, 66 A, and 262 W must be matched to the power supply's output capabilities.

Geometry Compatibility: Confirm that the F4 reference geometry and 2 wires x 0.040 in diameter match the source holder's filament receptacle.
Electrical Matching: Ensure the evaporation power supply can deliver 3.97 V, 66 A, and 262 W to drive the filament.

FAQ

What are the exact electrical and thermal specifications required to operate the Atomfair F4 tungsten coil thermal filament?

The filament requires 3.97 V, 66 A, and 262 W, with a rated operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly to ensure proper performance in vacuum deposition.

What are the physical dimensions and wire configuration of the Atomfair F4 tungsten coil thermal filament, and how do they affect compatibility with evaporation source holders?

The filament features an F4 geometry with 2 wires of 0.040 in diameter, forming 6 coils with a length of 4 inches and an inner diameter ranging from 1/4 in to 1 3/4 in. These dimensions must be confirmed against the holder fit before purchase.

What package quantities are available for the Atomfair F4 tungsten coil thermal filament, and how should the choice be made for laboratory workflows?

The filament is available in packages of 5 pcs or 10 pcs. The choice depends on the required quantity for the deposition run or maintenance schedule, as both packages contain identical filaments.

Assessment

Tungsten coil thermal filament in F4 geometry with dual 0.040 in wires, rated for 1800 °C, 3.97 V, 66 A, and 262 W, offered in 5- or 10-piece packages for vacuum deposition source assemblies.

Positive

Defined electrical loading for source matching: The specified 3.97 V, 66 A, and 262 W electrical parameters permit pre-purchase verification against the evaporation power supply and source assembly, reducing integration risk.
Rated operating temperature reference: An 1800 °C operating temperature rating provides a defined thermal reference point for configuring vacuum deposition processes that require this tungsten filament geometry.

Trade-offs

Mandatory pre-purchase fit confirmation: The F4 geometry, wire diameter, coil dimensions, and holder fit must be confirmed before ordering, and voltage, current, and power must be matched to the deposition system's power supply and source assembly.
Upfront package quantity selection: Buyers must select a 5-piece or 10-piece package at purchase, requiring advance inventory planning based on expected deposition run volume.
