Brand: ATOMFAIR®

This tungsten filament requires careful matching of electrical specifications and holder geometry for proper operation. The filament must be used within the rated operating temperature of 1800 °C and only with power supplies capable of delivering 2.04 V, 64 A, and 131 W.

Geometry Compatibility: The P4 geometry reference must be confirmed compatible with the evaporation source holder before installation.
Electrical Matching: The filament's 2.04 V, 64 A, and 131 W specifications must be matched to the power supply and source assembly.
Operating Temperature: The filament is rated for continuous operation at 1800 °C; exceeding this temperature may cause failure.
Package Quantity: Select the appropriate package size (5 or 10 pieces) based on anticipated usage and replacement schedule.
Wire Specification: The 3-wire, 0.030-inch diameter construction is fixed and cannot be modified; ensure it matches the source assembly design.

FAQ

What are the precise electrical and thermal specifications of the P4 tungsten point source filament and how do they constrain power supply selection?

The P4 tungsten point source filament is rated at 2.04 V, 64 A, and 131 W at an operating temperature of 1800 °C. These values must be matched to the evaporation power supply to ensure proper resistive heating and avoid overloading; any deviation may result in insufficient evaporation rates or filament failure.

What physical dimensions and wire configuration define the P4 geometry and how do they ensure compatibility with standard evaporation source holders?

The P4 geometry specifies a 3-wire construction with 0.030 in diameter per wire and overall dimensions of 5 in L x 1/2 in H x 1 in. These parameters are designed to fit standard vacuum deposition source assemblies; users should verify holder fit using the listed geometry reference before procurement.

Assessment

This tungsten point source filament (P4 geometry, 3 wires x 0.030 in diameter) is rated for 1800 °C operation with defined electrical parameters (2.04 V, 64 A, 131 W), requiring pre-purchase verification of holder fit and power supply compatibility for thermal evaporation deposition systems.

Positive

Defined electrical and thermal operating parameters: Rated at 1800 °C with specified 2.04 V, 64 A, and 131 W, enabling precise source matching during procurement review.
Tungsten construction with P4 geometry: Three-wire 0.030 in diameter tungsten filament in P4 geometry provides a consistent point source for thermal evaporation workflows.

Trade-offs

Requires pre-purchase geometry and holder fit verification: The filament geometry reference P4 and holder fit must be confirmed before quotation to ensure compatibility with the evaporation source assembly.
Electrical loading must match existing power supply: Voltage (2.04 V), current (64 A), and power (131 W) specifications must be matched to the evaporation power supply and source assembly to avoid operational mismatch.
