This filament requires a power supply that delivers the specified voltage, current, and power ratings to avoid electrical overload. The 1800°C operating temperature establishes the maximum thermal limit for the evaporation source assembly.
- Electrical Matching Requirement: The filament must be driven by a power supply that matches the 3.13 V, 79 A, and 247 W ratings to prevent damage or inconsistent evaporation.
- Thermal Operating Limit: The filament's rated operating temperature of 1800°C defines the maximum allowable thermal load for the evaporation source.
What are the electrical and thermal specifications of the Atomfair P5 tungsten point source filament with 4 wires x 0.030 in diameter?
The filament is rated for 1800 °C operation with a drive voltage of 3.13 V, current of 79 A, and power of 247 W. These values are specified for the P5 geometry with 4 wires of 0.030 in diameter and must be matched to the evaporation power supply and source assembly before use.
Does the P5 geometry filament fit standard thermal evaporation source holders, and what package sizes are available?
The filament uses a P5 reference geometry with overall dimensions of 4 in L x 1/2 in x 1/2 in. It is available in packages of 5 or 10 pieces. Users must confirm holder fit and geometry compatibility with their deposition system before ordering.
What handling or storage considerations apply to tungsten point source filaments for vacuum deposition?
Tungsten filaments are mechanically fragile and should be handled with clean gloves to avoid contamination that can affect evaporation uniformity. Store in a dry, low-humidity environment to prevent oxidation. The product is a research-grade laboratory item intended for thermal filament evaporation workflows.
This tungsten point source filament with P5 geometry and 4 wires of 0.030 in diameter is specified for 1800°C operation at 3.13V, 79A, 247W, enabling precise thermal evaporation in vacuum deposition systems when holder and power supply are matched accordingly.
Positive
- Defined geometry and wire configuration: The P5 geometry with 4 wires of 0.030 in diameter provides a controlled, reproducible thermal evaporation source geometry for consistent thin-film deposition.
- Explicit electrical ratings: Rated voltage (3.13V), current (79A), and power (247W) are specified, allowing direct matching with the evaporation power supply to avoid overloading or underperformance.
Trade-offs
- Requires fit and compatibility verification: The filament geometry (P5) and holder fit must be confirmed before purchase, and the electrical ratings must match the deposition system's power supply to ensure safe operation.
- High-temperature operation constraints: Operating at 1800°C demands proper vacuum conditions, thermal management, and handling procedures to prevent contamination or damage to the filament and surrounding components.
