Brand: ATOMFAIR®

This filament requires precise matching of geometry and electrical parameters to the evaporation source holder and power supply. Operation at 1800 °C demands a vacuum environment and proper handling to avoid damage.

Geometry Fit Verification: Verify that the F3 geometry, 6 coils, 5-inch length, and 2-inch-3/16-inch inner diameter fit the evaporation source holder before installation.
Electrical Matching: Confirm that the power supply can deliver 4.61 V, 48 A, and 221 W to match the filament's electrical specification.
Vacuum Environment Requirement: Operate the filament only in a vacuum environment to prevent oxidation at its rated 1800 °C temperature.
Handling Precautions: Handle the 3-wire, 0.025-inch diameter tungsten filament carefully to avoid wire breakage during loading.

FAQ

What are the exact electrical specifications of the Atomfair F3 tungsten coil filament and how should they be matched to a power supply?

The filament is rated at 4.61 V, 48 A, and 221 W with an operating temperature of 1800 °C. These values must be matched to the evaporation power supply to ensure proper resistive heating and avoid overcurrent or underpower conditions. The 3-wire, 0.025-inch diameter construction determines the resistance path, so the power supply should be capable of delivering the specified voltage and current simultaneously.

Which source holder dimensions are required to accommodate the F3 geometry tungsten coil filament?

The filament has an F3 reference geometry with 6 coils, a length of 5 inches, and an inner diameter of 2-3/16 inches. The source holder must physically fit these dimensions and support the 3-wire x 0.025-inch diameter wire configuration. Confirm holder compatibility before procurement to avoid mechanical mismatch in the vacuum deposition assembly.

Assessment

Tungsten coil thermal filament with F3 geometry, 3 wires × 0.025 in diameter, rated for 1800 °C operation at 4.61 V, 48 A, and 221 W, intended for matched integration into vacuum deposition source assemblies.

Positive

Defined electrical and thermal specs: Pre-specified 4.61 V, 48 A, 221 W and 1800 °C operating temperature allow direct compatibility checking with existing evaporation power supplies and source holders before procurement.
Multi-wire geometry for uniformity: Three-wire, 0.025 in diameter construction in F3 geometry supports consistent thermal evaporation profiles in vacuum deposition systems requiring a defined filament shape.

Trade-offs

Holder and power supply matching required: The F3 geometry, voltage, current, and power must be verified against the specific evaporation source holder and power supply; mismatch can prevent operation or damage equipment.
Package quantity selection needed pre-order: Available in 5 or 10 pcs per pack; the user must select the correct quantity and confirm the 6-coil, 5 in L × 2 in-3/16 inid format fits the deposition tool before purchase.
