What are the exact electrical requirements for the Atomfair AF-TCF2-4W030 tungsten coil thermal filament?

The filament requires 2.7 V, 77 A, and 208 W for operation at 1800 °C. These values are specified for the 4-wire, 0.030-inch diameter construction in the F2 geometry. Users must ensure their power supply can deliver these parameters.

How do I verify that the F2 geometry tungsten coil filament will fit my evaporation source holder?

The filament has an F2 reference geometry with dimensions: 4 coils, 4 inches in length, and an inner diameter range of 1 3/4 to 3/16 inches. Verify that your evaporation source holder accommodates these dimensions and the 4-wire configuration before ordering.

Why is the 0.030-inch wire diameter critical for the thermal evaporation performance of this filament?

The 0.030-inch wire diameter, combined with four wires, is designed to achieve the specified electrical characteristics of 2.7 V, 77 A, and 208 W at the rated 1800 °C operating temperature. This geometry ensures proper resistance heating for consistent thermal evaporation.

Assessment

The Tungsten Coil Thermal Filament (F2 geometry, 4 wires × 0.030 in diameter) is specified for 1800 °C operation at 2.7 V, 77 A, and 208 W, enabling precise electrical matching for thermal evaporation sources. The fixed wire count, diameter, and coil dimensions (4 in L × 1 3/4–3/16 in ID) impose holder and power supply compatibility requirements that must be verified before procurement.

Positive

Predefined electrical and thermal specs: Rated voltage (2.7 V), current (77 A), power (208 W), and operating temperature (1800 °C) allow direct matching to evaporation power supplies and source holders, reducing trial‑and‑error in system integration.
Consistent multi‑wire geometry: The 4‑wire × 0.030 in diameter construction with F2 geometry provides a uniform evaporation source footprint, essential for repeatable thin‑film deposition in vacuum thermal processes.

Trade-offs

Mandatory fit verification required: The filament’s F2 geometry, 4 in length, and coil ID range (1 3/4–3/16 in) must be confirmed compatible with the evaporation source holder; mismatch can cause improper electrical contact or mechanical instability.
Limited package quantity options: Available only in 5‑piece or 10‑piece packages; users requiring larger single‑lot quantities must order multiple packs, which may impact inventory management for high‑throughput labs.
