This tungsten coil filament requires exact geometry and electrical matching to the evaporation source holder and power supply. Use only within the rated 1800 °C operating temperature and specified wire configuration.

Geometry Compatibility: Confirm the F4 geometry reference, coil dimensions (4 in L x 1 3/4 in-1/4 in ID), and 4-wire × 0.030 in diameter construction fit the source holder before installation.
Electrical Matching: Match the filament drive voltage (3.63 V), current (73 A), and power (265 W) to the evaporation power supply specifications to prevent under- or over-driving.
Temperature Limit: Operate the filament only up to the rated 1800 °C maximum to avoid material degradation or failure during thermal evaporation.

FAQ

What are the rated voltage, current, and power specifications of the Atomfair F4 tungsten coil thermal filament, and how should these be matched to a deposition power supply?

The F4 tungsten coil filament is rated for 3.63 V, 73 A, and 265 W at an operating temperature of 1800 °C. These electrical values must be matched to the evaporation power supply and source assembly used in the deposition system to ensure proper thermal evaporation performance.

What are the physical dimensions and wire configuration of the F4 tungsten coil filament for compatibility with vacuum deposition source holders?

The F4 geometry filament features 4 wires each 0.030 in diameter, formed into 6 coils with an overall length of 4 inches and an inner diameter ranging from 1/4 in to 1 3/4 in. Confirm that the filament geometry reference F4 and holder fit match your evaporation source assembly before ordering.

Assessment

This tungsten coil thermal filament with F4 geometry and 4-wire, 0.030-inch diameter construction is specified for 1800°C operation with defined electrical ratings (3.63V, 73A, 265W), enabling direct integration into matched evaporation source assemblies. The technical evaluation confirms that proper holder fit and power supply compatibility are critical prerequisites for reliable performance.

Positive

Defined Electrical Parameters for Source Matching: The 3.63 V, 73 A, and 265 W rating allows direct matching with evaporation power supplies, reducing trial-and-error during setup and ensuring consistent thermal output.
Reproducible Filament Geometry: The F4 geometry with 4 wires x 0.030 in diameter and 6-coil, 4 in L x 1 3/4 in–1/4 in ID format provides a defined physical footprint that supports repeatable deposition conditions across filament changes.

Trade-offs

Holder Compatibility Verification Required: The F4 geometry and specific dimensions (4 in L, 1 3/4 in–1/4 in ID) require manual confirmation of fit with the existing evaporation source holder before purchase.
Fixed Electrical Ratings Limit Flexibility: The filament is rated for 3.63 V, 73 A, and 265 W; power supplies unable to deliver these exact values will not achieve the specified 1800°C operating temperature, potentially compromising deposition performance.
