This filament requires exact electrical matching to the evaporation power supply and source holder to prevent overheating or failure. It must be operated within the rated 1800°C temperature limit to avoid degradation.
- Electrical Matching: Voltage, current, and power values must be matched to the power supply and source assembly before operation.
- Operating Temperature Limit: Do not exceed the rated 1800°C operating temperature to prevent filament damage.
What are the electrical and thermal specifications of the Atomfair P2 tungsten point source filament, and how do they constrain power supply selection?
The filament is rated for 1.84 V, 75 A, 138 W, and an operating temperature of 1800 °C. These values must be matched to the evaporation power supply and source assembly used in the deposition system to ensure proper thermal evaporation performance and avoid damage.
What does the P2 geometry reference mean for compatibility with existing vacuum deposition source holders?
The P2 geometry defines a specific filament shape with dimensions of 4 1/2 in L x 2 in x 1/2 in. Users must confirm that their source holder accommodates this geometry before purchase; the product description explicitly advises verifying holder fit and geometry reference P2 prior to quotation.
What is the significance of the 1 Wire x 0.060 in Diameter construction for thermal evaporation performance?
The single wire with 0.060 inch diameter defines the filament's resistance and directly determines the electrical loading (1.84 V, 75 A, 138 W) and operating temperature (1800 °C). This construction must be matched to the evaporation source assembly and power supply to achieve the intended thermal evaporation conditions.
This tungsten point source filament (P2 geometry, 1 wire x 0.060 in diameter) is rated for 1800°C operation with specified electrical parameters of 1.84 V, 75 A, and 138 W, enabling precise thermal evaporation but requiring careful holder fit and power supply matching.
Positive
- High-temperature operation: Rated operating temperature of 1800 °C provides a defined reference point for thermal evaporation configuration selection, supporting consistent deposition conditions.
- Specified electrical parameters: Electrical specification of 1.84 V, 75 A, and 138 W enables precise source matching during procurement review, ensuring compatibility with the evaporation power supply and source assembly.
Trade-offs
- Holder fit compatibility required: The P2 geometry and physical dimensions (4 1/2 in L x 2 in x 1/2 in) require confirmation of fit with the evaporation source holder before use, as the filament is not universally compatible.
- Power supply matching required: The fixed electrical parameters (1.84 V, 75 A, 138 W) necessitate precise matching with the deposition system's power supply, limiting flexibility if the supply cannot deliver these exact values.
