Description

4 Coil (Short)

Tungsten Basket Filament Key Features:

• Voltage:31 V
• Current:44 A
• Power:234 W
• Operating Temperature:~1800°C
• Construction:3 strands of 0.025″ high-purity tungsten
• Design:4-coil basket for balanced material loading and uniform heating
• Evaporation Direction:Suitable for upward and downward use

With a calculated resistance of ~0.1207 Ω, this filament is optimized for 1 kVA low-voltage power supplies that support higher voltage operation. Its design balances power draw with thermal stability, providing excellent performance for metals, organics, and other vacuum-deposited materials.

Ideal For:

• Medium to high-power thermal evaporation
• Thin film and optical coating applications
• Materials that require sustained heating for clean deposition
• Labs and production environments needing flexible directional evaporation

Why Choose This Filament?

• Higher wattage (234 W) allows for faster material throughput
• Stable at 1800°C with clean, consistent evaporation
• 4-coil design ensures uniform heating and material use
• Compatible with standard LV power systems (~1 kVA)
• Supports bothupward and downward evaporation setups

When your process requires more power without sacrificing control, this 3-strand, 4-coil tungsten basket filament offers the performance and flexibility needed for quality thermal deposition.
