What are the electrical requirements for the Atomfair F3 tungsten coil thermal filament and how do I match them to my power supply?

The filament requires 4 V, 68 A, and 272 W at an operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly used in the deposition system. The wire specification is 2 wires x 0.040 in diameter.

What are the physical dimensions and geometry of the F3 tungsten coil filament and how do I confirm fit in my evaporation source holder?

The filament has F3 reference geometry with 6 coils, 5 inches length, and 2 in-3/16 in inner diameter. It is constructed with 2 wires of 0.040 in diameter. Confirm the geometry reference F3 and holder fit before quotation.

Assessment

The F3 geometry tungsten coil thermal filament with 2 wires x 0.040 in diameter is specified for 1800 °C operation at 4 V, 68 A, and 272 W, making it suitable for thermal evaporation source assemblies requiring defined wire count and diameter. The 6-coil, 5 in L x 2 in-3/16 in ID format supports vacuum deposition workflows where geometry and electrical loading must be matched to the power supply and holder.

Positive

Defined electrical and thermal specs: Rated at 4 V, 68 A, 272 W, and 1800 °C, the filament provides a clear reference for matching to evaporation power supplies and source assemblies, reducing procurement uncertainty.
Consistent F3 geometry with wire count: The 2-wire x 0.040 in diameter construction in F3 geometry ensures repeatable deposition conditions for users requiring a specific filament configuration.

Trade-offs

Fixed geometry limits holder compatibility: The F3 geometry and 5 in L x 2 in-3/16 in ID format require exact holder fit; users must verify compatibility with their evaporation source assembly before purchase.
Electrical loading must match power supply: Operation at 68 A and 272 W demands a power supply capable of delivering these values; mismatched supplies may cause underperformance or damage.
