Tungsten Point Source Filament P5 0.040 in ATOMFAIR®

Tungsten Point Source Filament, P5 Geometry, 1 Wire x 0.040 in Diameter

Product Type: Thermal filament point source

Research-grade laboratory product

Product Overview

Tungsten Point Source Filament, P5 Geometry, 1 Wire x 0.040 in Diameter is a tungsten thermal evaporation filament specified for 1800 °C operation, 3.44 V drive voltage, 40 A current and 138 W power. The 1 Wire x 0.040 in Diameter construction and 5 pcs/package and 10 pcs/package; 4 in L x 1/2 in H-1/2 in-4 format support selection for vacuum deposition source assemblies that require a defined tungsten filament geometry.

The item is intended for thermal filament evaporation workflows where wire count, wire diameter, source geometry and electrical loading must be matched before purchase. Use the listed geometry reference and electrical values to confirm fit with the evaporation source holder and power supply configuration.

Manufacturer: Atomfair LLC

Brand: ATOMFAIR®

The filament is rated for operation at 3.44V, 40A, 138W, and 1800°C; exceeding these values may cause filament failure or safety hazards. Use in a vacuum environment is required to prevent oxidation and ensure proper thermal evaporation performance.

Electrical Operating Limits: Do not exceed the specified voltage of 3.44V, current of 40A, or power of 138W.
Temperature Limit: Do not exceed the rated operating temperature of 1800°C.
Vacuum Requirement: Use the filament only in a vacuum chamber to prevent oxidation at high temperature.
Geometry and Fit Confirmation: Confirm the filament geometry reference P5 and holder fit before installation to ensure proper operation.
Power Supply Matching: Ensure the power supply is capable of delivering the required voltage, current, and power for the filament.

FAQ

What are the electrical requirements for the P5 tungsten point source filament and how do they affect power supply selection?

The filament requires 3.44 V, 40 A, and 138 W at its rated operating temperature of 1800 °C. These values must be matched to the evaporation power supply to ensure stable thermal evaporation; the product description explicitly lists these specifications for source matching during procurement review.

Does the P5 geometry filament fit standard thermal evaporation source holders?

The filament uses a defined P5 geometry with dimensions of 4 in L x 1/2 in H-1/2 in-4 format. Users must confirm holder fit before purchase, as the product description states that the geometry reference and holder fit should be verified prior to quotation.

What is the maximum operating temperature of this tungsten filament and what are the implications for vacuum deposition?

The filament is rated for operation at 1800 °C, which serves as a defined reference point for thermal evaporation configuration selection. Tungsten filaments require vacuum conditions to prevent oxidation at such high temperatures; the product is intended for vacuum deposition source assemblies.

Assessment

This tungsten point source filament with P5 geometry provides defined electrical ratings (3.44 V, 40 A, 138 W) for thermal evaporation applications; however, users must verify holder fit and power supply matching before purchase to ensure compatibility.

Positive

Defined electrical ratings enable system matching: The filament specifies voltage (3.44 V), current (40 A), and power (138 W), allowing direct comparison with power supply capabilities during procurement.
Standardized P5 geometry for source compatibility: The P5 geometry and 0.040 in wire diameter provide a known form factor that simplifies integration with compatible evaporation source holders.

Trade-offs

Pre-purchase compatibility verification mandatory: The filament requires confirmation of holder fit and electrical matching before ordering to avoid incompatibility with existing deposition systems.
Package quantity limited to two options: The filament is only available in packages of 5 or 10 pieces, which may not align with all experimental or production volume requirements.
