The filament must be used with a deposition source holder that conforms to the F11 geometry and a power supply capable of delivering 7.07 V, 58 A, and 410 W. The rated operating temperature of 1800 °C defines the maximum allowable thermal exposure during evaporation.
- Geometry Compatibility: The deposition source holder must accept the F11 coil geometry with 6 coils, 5 in length, and 2.5 in inner diameter.
- Electrical Matching: The power supply must be capable of providing 7.07 V, 58 A, and 410 W to the filament assembly.
- Temperature Limit: The filament must not be operated above its rated temperature of 1800 °C to prevent structural failure.
What is the significance of the 3 wires x 0.030 in diameter construction for thermal evaporation performance?
The 3-wire configuration with 0.030 in diameter per wire provides a defined resistance and surface area for uniform heating and controlled evaporation rates. This geometry, combined with the F11 coil form (6 coils, 5 in length, 2-1/2 in ID), ensures consistent thermal distribution at the rated 1800 °C operating temperature, which is critical for reproducible thin-film deposition.
How do I verify that the F11 geometry filament will fit my existing evaporation source holder?
Confirm the filament geometry reference F11, overall dimensions of 5 in length and 2-1/2 in inner diameter, and the 6-coil structure match your source holder's physical constraints. Additionally, ensure your power supply can deliver the specified 7.07 V, 58 A, and 410 W, as these electrical parameters are integral to proper fit and operation within the deposition system.
What are the electrical and thermal requirements for operating this tungsten coil filament at 1800 °C?
The filament requires a drive voltage of 7.07 V, current of 58 A, and power of 410 W to reach its rated operating temperature of 1800 °C. The power supply must be capable of delivering these values continuously, and the source assembly must be rated for the thermal load to avoid overheating or mechanical failure during evaporation.
The F11 geometry tungsten coil thermal filament with 3 wires x 0.030 in diameter is specified for 1800 °C operation at 7.07 V, 58 A, and 410 W, making it suitable for thermal evaporation workflows requiring a defined wire count and diameter. The 6-coil, 5 in L x 2 in-1/2 in ID format must be matched to the evaporation source holder and power supply before purchase.
Positive
- Defined electrical and thermal specs: Rated at 7.07 V, 58 A, 410 W, and 1800 °C, the filament provides a clear reference for matching to evaporation power supplies and source assemblies, reducing trial-and-error during procurement.
- Multiple package size options: Available in 5 pcs/package and 10 pcs/package configurations, allowing labs to select quantities that match deposition run frequency without overstocking.
Trade-offs
- Geometry-specific holder fit required: The F11 geometry and 5 in L x 2 in-1/2 in ID format must be verified against the evaporation source holder; incorrect fit can prevent installation or cause arcing.
- Fixed electrical loading constraints: The 7.07 V, 58 A, and 410 W ratings are fixed; the filament cannot be used with power supplies that cannot deliver these exact parameters without risking underperformance or damage.
