Tungsten coil thermal filaments require pre-installation confirmation of source geometry and electrical load compatibility. This item must be matched to the evaporation source holder and power supply configuration before use.
- Geometry and holder compatibility: Confirm the F14 geometry reference and holder fit with the evaporation source assembly before purchase.
- Workflow and electrical matching: Verify the wire count, wire diameter, source geometry, and electrical loading requirements against the evaporation workflow before ordering.
- Power supply and source assembly compatibility: Match the filament voltage, current, and power requirements to the evaporation power supply and source assembly used in the deposition system.
This procedure covers geometry confirmation and electrical matching for the F14 tungsten coil thermal filament. Complete these steps before deploying the filament in a vacuum deposition source assembly.
Required Equipment: Evaporation source holder, Evaporation power supply
- Confirm geometry and holder compatibility
Confirm the F14 geometry reference and holder fit with the evaporation source assembly before purchase. - Verify package quantity
Verify the required package quantity before quotation. - Match electrical loading
Match the filament's electrical loading to the evaporation power supply and source assembly used in the deposition system. - Set deposition reference
Use the manufacturer-specified operating temperature as the reference point when configuring thermal evaporation parameters.
What is the significance of the F14 geometry and 3-wire 0.040 in diameter construction for thermal evaporation performance?
The F14 geometry with 3 wires of 0.040 in diameter defines a specific coil configuration—8 coils, 2 in L x 1 in H x 1/2 in ID—that ensures uniform heating and consistent evaporation rates. The electrical ratings of 8.2 V, 88 A, and 722 W are matched to this geometry to achieve the rated 1800 °C operating temperature, which is critical for reproducible thin-film deposition in vacuum thermal evaporation systems.
How do I verify that this tungsten coil filament is compatible with my existing evaporation source holder and power supply?
Compatibility requires matching the filament geometry reference F14 to the source holder's coil pocket dimensions (2 in L x 1 in H x 1/2 in ID) and ensuring the power supply can deliver 8.2 V at 88 A (722 W). The wire count (3 wires) and diameter (0.040 in) also affect electrical resistance and thermal profile; confirm these against your source assembly specifications before ordering.
What handling precautions are required for tungsten coil thermal filaments to prevent damage or contamination?
Tungsten filaments are brittle and sensitive to contamination. Handle with clean gloves, avoid bending the coil geometry, and store in a dry, inert environment to prevent oxidation. The filament is rated for 1800 °C operation; ensure proper vacuum conditions to avoid rapid oxidation at high temperatures during use.
The AF-TCF14-3W040 tungsten coil thermal filament features a 3-wire × 0.040 in diameter F14 geometry, rated for 1800 °C operation at 8.2 V, 88 A, and 722 W, enabling precise electrical matching for vacuum deposition source assemblies.
Positive
- High-temperature rated operation: Rated operating temperature of 1800 °C provides a defined reference point for thermal evaporation configuration selection, supporting high-vacuum deposition processes.
- Precisely defined electrical specs: Electrical specification of 8.2 V, 88 A, and 722 W enables direct matching with power supply and source assembly before procurement, reducing integration risk.
Trade-offs
- Holder geometry compatibility required: Confirm filament geometry reference F14, holder fit, and required package quantity before quotation, as physical fit depends on the specific evaporation source assembly.
- Power supply matching needed: Voltage, current, and power requirements must be matched to the evaporation power supply and source assembly used in the deposition system, which may require existing infrastructure.
