This tungsten coil thermal filament must be matched to the evaporation source holder and power supply before installation. The F3 geometry and electrical ratings of 3.91 V, 39 A, and 152 W determine compatibility with specific deposition system configurations.

Geometry and Holder Fit: Confirm the filament geometry reference F3 and holder fit before ordering to ensure physical compatibility with the source assembly.
Electrical Matching: Match the voltage, current, and power requirements to the evaporation power supply used in the deposition system.

FAQ

How do I confirm that the Atomfair AF-TCF3-1W040 tungsten coil filament is compatible with my existing thermal evaporation system?

Verify the F3 geometry reference, holder fit, and electrical specifications against your evaporation source holder and power supply. The filament is specified for 1800°C operation with 3.91 V, 39 A, and 152 W. Use the listed geometry (6 coils, 5 in L x 2 in-3/16 in ID) to check mechanical fit, and match voltage, current, and power to your power supply's output capabilities.

What is the significance of the 1 Wire x 0.040 in diameter construction for thermal evaporation applications?

The 1 Wire x 0.040 in diameter construction defines the filament's resistance and current-carrying capacity, directly affecting the electrical loading and heating profile. This geometry, combined with the F3 coil configuration, is designed to provide a stable, repeatable evaporation source at 1800°C. Selecting the correct wire diameter and coil geometry is critical for achieving uniform deposition rates and avoiding premature filament failure.

Assessment

Tungsten coil thermal filament with F3 geometry, 1 wire x 0.040 in diameter, rated for 1800°C operation at 3.91 V, 39 A, and 152 W. Suitable for vacuum thermal evaporation when source geometry and electrical loading are matched to the deposition system.

Positive

Defined electrical specifications: Voltage (3.91 V), current (39 A), and power (152 W) values are explicitly stated, enabling direct matching with evaporation power supplies and source assemblies during procurement.
High-temperature tungsten construction: Rated operating temperature of 1800°C and tungsten filament material provide a stable, high-temperature source for thermal evaporation workflows.

Trade-offs

Exact power supply matching required: The specified voltage, current, and power must be precisely matched to the evaporation power supply; deviation may cause suboptimal performance or damage.
Holder compatibility dependent on F3 geometry: The F3 geometry reference and physical dimensions (6 coils, 5 in L x 2 in-3/16 in ID) require confirmation of holder fit before purchase to ensure proper installation.
