This document outlines the compatibility and matching constraints for the Tungsten Coil Thermal Filament F4. Users must verify filament geometry, electrical specifications, and package quantity against their deposition system before purchase.

Geometry and Holder Fit: The filament's F4 geometry must be confirmed to fit the evaporation source holder.
Electrical Specifications Matching: The filament's electrical specifications must be matched to the power supply and source assembly of the deposition system.
Package Quantity Selection: The required package quantity must be selected based on the number of filaments needed.

FAQ

What are the exact electrical specifications of the Atomfair F4 tungsten coil filament and how should they be matched to a power supply?

The filament is rated at 3.7 V, 38 A, and 141 W at 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. The single-wire 0.040 in diameter construction defines the resistance and thus the electrical load, so the power supply must be capable of delivering these parameters continuously.

What is the F4 geometry and how does it ensure compatibility with vacuum deposition systems?

The F4 geometry refers to a specific coil configuration: 6 coils, 4 inches in length with an inner diameter tapering from 1 3/4 in to 1/4 in. This defined geometry is designed for use in vacuum deposition source assemblies that require a precise tungsten filament shape. Users must confirm that the filament holder and source assembly accept this geometry before purchase, as the fit directly affects deposition uniformity and filament lifetime.

Assessment

Tungsten Coil Thermal Filament, F4 Geometry, 1 Wire x 0.040 in Diameter provides a defined 1800°C thermal evaporation source with specified electrical loading of 3.7V, 38A, 141W, requiring careful matching to existing source holder and power supply before deployment.

Positive

High-temperature tungsten filament for thermal evaporation: Rated for 1800°C operation, providing a defined reference point for thermal evaporation configuration selection in vacuum deposition workflows.
Defined electrical specifications for source matching: Electrical specification of 3.7 V, 38 A, and 141 W supports accurate source matching during procurement review to ensure compatibility with the evaporation power supply.

Trade-offs

Geometry and holder fit must be confirmed: The filament geometry reference F4, holder fit, and required package quantity must be verified before quotation to ensure mechanical compatibility with the evaporation source assembly.
Voltage, current, and power must match power supply: The electrical loading (3.7 V, 38 A, 141 W) must be matched to the evaporation power supply and source assembly used in the deposition system to avoid operational issues.
