This tungsten filament must be operated within the specified voltage (3.43 V), current (49 A), and power (168 W) ratings to prevent electrical overload. The filament geometry must match the evaporation source holder and the power supply must be configured to the listed electrical parameters before use.
- Electrical Rating Compatibility: The filament is rated for 3.43 V, 49 A, and 168 W; operation outside these values may cause overheating or failure.
- Geometry Verification: Confirm that the F2 geometry, wire count (3 wires), and wire diameter (0.025 in) fit the source holder and coil ID range (3/16 in to 1-3/4 in).
- Package Selection: Select the package size (5 or 10 pieces) and verify the coil dimensions match the source assembly requirements.
- Vacuum System Compatibility: This filament is designed for vacuum thermal evaporation; ensure the deposition system is under appropriate vacuum conditions.
- Operating Temperature Reference: The filament is specified for 1800 °C operation; use this as a reference for thermal evaporation configuration.
Follow these steps to safely install and operate the tungsten coil filament for thermal evaporation. Ensure all electrical and mechanical parameters are matched to the deposition system.
Required Equipment: Evaporation Power Supply, Source Holder Assembly
- Confirm Geometry Compatibility
Confirm the filament geometry matches the evaporation source holder dimensions and coil ID range. - Set Power Supply Parameters
Set the power supply voltage to 3.43 V and current limit to 49 A before connecting the filament. - Install Filament
Install the filament into the source assembly, ensuring secure mechanical and electrical connections. - Energize and Verify
Energize the filament and verify the voltage and current remain stable at the specified ratings.
What are the exact electrical operating parameters of the Atomfair AF-TCF2-3W025 tungsten coil thermal filament and how should they be matched to a deposition power supply?
The filament operates at 3.43 V, 49 A, and 168 W with a rated temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly to ensure proper thermal evaporation performance. The F2 geometry and 3 wires x 0.025 in diameter construction define the resistance characteristics that produce these electrical requirements.
What are the physical dimensions and geometry of the F2 tungsten coil filament and how do they ensure compatibility with standard vacuum deposition source holders?
The filament features an F2 reference geometry with 4 coils, 4 inches in length, and an inner diameter ranging from 1-3/4 inches to 3/16 inches. This specific geometry is designed to fit standard thermal evaporation source assemblies. Users must confirm holder fit and geometry reference before purchase.
What is the significance of the 3 wires x 0.025 in diameter construction in the F2 geometry tungsten coil?
The three-wire construction with 0.025-inch diameter wires provides a specific resistance and surface area for efficient thermal evaporation at 1800 °C. This wire configuration is critical for achieving the stated electrical parameters (3.43 V, 49 A, 168 W) and uniform heating across the coil.
This tungsten coil thermal filament with F2 geometry and 3 wires of 0.025 in diameter is engineered for 1800°C thermal evaporation, with defined electrical ratings (3.43 V, 49 A, 168 W) that enable precise matching to deposition power supplies and source holders.
Positive
- Defined wire geometry for source matching: The 3 wires x 0.025 in diameter construction with F2 geometry provides a precise filament configuration for thermal evaporation source assemblies, enabling reproducible deposition conditions.
- Electrical ratings enable power supply compatibility: Specified at 3.43 V, 49 A, and 168 W, this filament allows direct verification of compatibility with the evaporation power supply and source assembly before purchase.
Trade-offs
- Holder fit must be confirmed before use: The filament geometry F2 requires exact mechanical fit with the evaporation source holder; incorrect holder compatibility will prevent proper installation and operation.
- Electrical load must match existing power supply: The fixed voltage, current, and power ratings demand that the user's power supply can deliver 3.43 V at 49 A continuously; mismatched supply will cause underperformance or damage.
