What are the exact electrical ratings (voltage, current, power) required to operate the Atomfair F2 tungsten coil filament at its rated temperature?

The filament is rated for 3.08 V, 63 A, and 194 W to achieve an operating temperature of 1800 °C. These values must be matched by the evaporation power supply for proper performance.

What physical dimensions and geometry must be verified to ensure the Atomfair F2 tungsten coil filament fits a specific thermal evaporation source holder?

The filament has an F2 geometry with 4 coils, an overall length of 4 inches, and an inner diameter ranging from 3/16 inch to 1 3/4 inches. The wire specification is 3 wires each 0.030 inches in diameter. These parameters should be confirmed against the holder's design.

What package quantities are available for the Atomfair F2 tungsten coil filament, and how should the quantity be selected?

The filament is offered in packages of 5 or 10 pieces per pack. Selection depends on the number of evaporation sources in the deposition system and the anticipated replacement frequency.

Assessment

This tungsten coil thermal filament with F2 geometry, 3 wires x 0.030 in diameter, is specified for 1800°C operation with 3.08 V, 63 A, 194 W electrical parameters, making it suitable for vacuum deposition systems requiring a defined source geometry and electrical loading.

Positive

Precise electrical specification: Rated at 3.08 V, 63 A, and 194 W, the filament enables direct matching to evaporation power supplies without iterative testing, reducing commissioning time.
Defined operating temperature: The 1800°C rated temperature provides a reliable reference point for thermal evaporation of materials with moderate vaporization temperatures, supporting consistent deposition rates.

Trade-offs

Holder fit must be verified: The F2 geometry with 4 coils, 4 in L x 1 3/4 in-3/16 in ID requires confirmation of physical compatibility with the specific evaporation source holder before purchase, as dimensions are not universal.
Fixed electrical loading: The non-adjustable 3.08 V, 63 A, 194 W rating demands a power supply that meets these exact values, limiting flexibility for systems with variable output capabilities.
