This tungsten coil thermal filament is designed for vacuum deposition at 1800 °C. Operation must be confined to the specified electrical parameters to prevent overheating and failure.

Electrical operating limits: The filament must be driven at 6.74 V and 65 A to maintain the rated power of 438 W.

FAQ

What are the exact electrical specifications of the F11 geometry tungsten coil filament and how should they be matched to a power supply?

The AF-TCF11-2W040 filament operates at 6.74 V, 65 A, and 438 W at its rated 1800 °C operating temperature. These values must be matched to the evaporation power supply's voltage and current capabilities to ensure proper resistive heating and avoid under- or over-powering the filament during thermal evaporation.

What are the physical dimensions of the F11 geometry tungsten coil filament and how do they affect compatibility with evaporation source holders?

The filament has 6 coils, a length of 5 inches, and an inner diameter of 2-1/2 inches. The F11 geometry reference and these dimensions must be confirmed against the source holder's design to ensure proper fit and alignment in the vacuum deposition system before purchase.

Assessment

This tungsten coil thermal filament (F11 geometry, 2 wires x 0.040 in) is rated for 1800°C operation with electrical specifications of 6.74 V, 65 A, and 438 W, making it suitable for thermal evaporation in vacuum deposition systems where precise source geometry and power matching are required.

Positive

High-temperature rating for thermal evaporation: Rated operating temperature of 1800°C provides a defined reference point for thermal evaporation configuration selection, enabling high-temperature deposition processes.
Precise electrical specifications for power matching: Specified voltage (6.74 V), current (65 A), and power (438 W) allow direct comparison with evaporation power supply ratings, reducing risk of electrical mismatch during procurement.

Trade-offs

Requires exact electrical compatibility verification: Voltage, current, and power must be matched to the deposition system's power supply; deviation can cause inadequate heating or filament failure.
Geometry-dependent holder fit confirmation needed: The F11 filament geometry and 2 wires x 0.040 in diameter require validation against the evaporation source holder before purchase to ensure mechanical compatibility.
