This document outlines the electrical, dimensional, and operational constraints for the Atomfair F11 tungsten coil thermal filament. Proper selection and use require matching the filament's specifications to the evaporation source assembly and power supply configuration.

Power Supply Compatibility: The filament requires a power supply capable of delivering 6.4 V, 70 A, and 443 W for proper operation.
Geometry Fit: The F11 geometry with 4 wires of 0.030 in diameter must be physically compatible with the evaporation source holder.
Operating Temperature Limit: The filament is rated for a maximum operating temperature of 1800 °C and should not be exceeded during use.
Vacuum Environment Requirement: Thermal evaporation must be performed in a vacuum deposition system to prevent oxidation and ensure proper filament operation.

FAQ

What electrical specifications must be matched to operate the F11 tungsten coil filament at its rated 1800°C operating temperature?

The F11 tungsten coil filament requires a power supply capable of delivering 6.4 V, 70 A, and 443 W to achieve its rated 1800°C operating temperature. These values are specified for the 4-wire x 0.030 in diameter construction and must be confirmed against the evaporation source assembly before use.

How does the F11 geometry (5 in L x 2 in-1/2 in ID) affect integration into existing thermal evaporation source holders?

The F11 geometry defines a coil with 6 turns, 5 inches in length, and 2-1/2 inches inner diameter. Users must verify that their source holder physically accommodates these dimensions and that the 4-wire x 0.030 in diameter leads match the terminal configuration. The product description emphasizes confirming holder fit before purchase.

Why is the 4-wire x 0.030 in diameter construction specified for this thermal evaporation filament?

The 4-wire construction with 0.030 in diameter per wire provides a defined resistance and surface area for uniform heating at 1800°C. The electrical ratings (6.4 V, 70 A, 443 W) are derived from this specific wire geometry, ensuring consistent evaporation rates when matched to the correct power supply.

Assessment

Tungsten coil thermal filament with F11 geometry, 4 wires of 0.030 in diameter, rated for 1800°C and 443W, requiring precise voltage (6.4V) and current (70A) matching to the evaporation power supply.

Positive

High-temperature rated operation: Rated operating temperature of 1800°C provides a defined reference point for thermal evaporation configuration selection, enabling reproducible deposition conditions.
Defined electrical specifications: Electrical specification of 6.4V, 70A, and 443W supports precise source matching during procurement review, reducing integration risk with the power supply.

Trade-offs

Holder fit confirmation required: The filament geometry reference F11, including 6 coils, 5 in L x 2 in-1/2 in ID, must be confirmed with the specific evaporation source holder before purchase to ensure mechanical compatibility.
Power supply matching mandatory: Voltage (6.4V), current (70A), and power (443W) requirements must be matched to the evaporation power supply and source assembly used in the deposition system to avoid operational failure.
