Confirm the filament geometry reference F11 and holder fit are compatible with the deposition source assembly before purchase. Ensure the power supply matches the filament's electrical ratings of 5.7 V, 87 A, and 496 W to prevent electrical overload.

Geometry and Holder Fit: Verify the filament geometry conforms to the F11 reference and fits the source holder.
Electrical Matching: Match the filament voltage, current, and power ratings to the evaporation power supply.

FAQ

What is the significance of the 3 wires x 0.040 in diameter construction for thermal evaporation performance?

The three-wire construction increases surface area and mechanical stability, allowing higher current (87 A) and power (496 W) at 1800 °C compared to single-wire filaments. This geometry supports uniform heating and longer operational life for consistent deposition rates.

How do I verify that the F11 geometry filament will fit my existing evaporation source holder?

The filament has 6 coils, 5 in length, and 2 in-1/2 in inner diameter. You must confirm that your source holder accommodates these dimensions and the F11 reference geometry. Additionally, match the electrical requirements (5.7 V, 87 A, 496 W) to your power supply's output capabilities.

What handling precautions are required for tungsten coil filaments to prevent contamination or damage?

Tungsten filaments are sensitive to surface contamination; handle with clean gloves and avoid touching the coil area. Store in original packaging to prevent deformation. The filament is rated for 1800 °C operation; ensure proper vacuum conditions to avoid oxidation at high temperature.

Assessment

This tungsten coil thermal filament offers a defined F11 geometry with 3 wires of 0.040 in diameter, rated for 1800°C operation at 5.7V, 87A, and 496W, making it suitable for controlled thermal evaporation in vacuum deposition systems. The product is available in packages of 5 or 10 pieces, and its electrical and geometric specifications must be verified against the existing source holder and power supply.

Positive

High-temperature 1800°C operation: Rated for continuous operation at 1800°C, this filament provides a stable thermal source for evaporation of materials with high melting points.
Pre-specified electrical parameters: Explicit voltage, current, and power ratings (5.7V, 87A, 496W) enable direct matching to deposition power supplies without trial-and-error.

Trade-offs

Holder geometry compatibility required: The F11 geometry and 6-coil, 5 in L x 2 in-1/2 in ID dimensions must be verified against the existing source holder; improper fit can lead to arcing or mechanical instability.
Electrical parameter matching mandatory: The specified 5.7V, 87A, and 496W require a power supply capable of delivering these exact values; off-spec operation risks filament damage or inconsistent evaporation rates.
