The basket heater must be operated under vacuum to prevent oxidation of tungsten wires at temperatures up to 1800°C. Electrical loading must be matched to the rated 5.31 V, 44 A, and 234 W to avoid thermal runaway or damage.
- Vacuum Environment Requirement: The heater is designed exclusively for vacuum evaporation and must not be energized in air above 200°C to prevent tungsten oxidation.
- Electrical Supply Matching: The power supply output must be set to 5.31 V and 44 A, within the 234 W rating, to avoid exceeding the heater's current capacity.
- Physical Fit Verification: The 3.5 in L x 0.75 in W x 0.5 in H dimensions must be confirmed against the source holder to ensure proper mechanical seating.
- Maximum Temperature Limit: The heater must not be operated above 1800°C as this exceeds the material's structural integrity threshold.
Install the basket heater into a vacuum evaporation source holder and connect to a matched power supply. Evacuate the chamber before applying power and monitor electrical parameters during operation.
Required Equipment: Vacuum evaporation system, Power supply (5.31 V, 44 A rated), Source holder compatible with 3.5 in L x 0.75 in W x 0.5 in H
- Confirm power supply settings
Confirm that the power supply is set to 5.31 V and 44 A, within the 234 W rating, before connecting the heater. - Verify physical fit
Measure the heater dimensions against the source holder to ensure the 3.5 in L x 0.75 in W x 0.5 in H geometry fits securely. - Mount the heater
Mount the basket heater into the source holder and tighten the electrical connections to the rated terminals. - Evacuate the chamber
Evacuate the vacuum chamber to the required operating pressure before applying any electrical power. - Apply power and monitor
Apply power at the rated voltage and current, and monitor the heater temperature to ensure it does not exceed 1800°C.
What are the electrical and temperature limits of the Atomfair AF-TBH35L75W5H3W0025C4V531A44W234P5 tungsten basket heater?
This tungsten basket heater is rated at 5.31 V, 44 A, and 234 W, with a maximum operating temperature of 1800 °C. These specifications are critical for matching the heater to a compatible power supply and ensuring it can sustain the thermal demands of vacuum evaporation processes without exceeding its design limits.
How do I verify physical compatibility of this 3-wire tungsten basket heater with my existing evaporation source holder?
Physical fit is determined by the heater's geometry: 3 wires each 0.025 inches in diameter, with overall dimensions of 3.5 inches in length, 0.75 inches in width, and 0.5 inches in height, and a 4-coil configuration. You must confirm that these dimensions match your source holder's basket receptacle and that the wire gauge is compatible with your electrode clamps before procurement.
What package options are available for this tungsten basket heater, and how should I select the right quantity?
This product is offered in packages of 5 or 10 pieces per pack. The choice depends on your anticipated usage rate and replacement schedule; ordering a 10-pack may be more economical for ongoing evaporation runs, while a 5-pack is suitable for initial testing or lower-throughput applications. Both options use the same Atomfair model AF-TBH35L75W5H3W0025C4V531A44W234P5.
This tungsten basket heater is rated for 1800°C operation with an electrical load of 5.31 V, 44 A, and 234 W, and features a 4-coil, 3-wire (0.025 in dia) construction measuring 3.5 in L x 0.75 in W x 0.5 in H. It is offered in 5 or 10 piece packages, and its geometry and power requirements must be verified against the evaporation source holder and heating supply before deployment.
Positive
- High-temperature evaporation capability: Rated for 1800°C, this basket heater supports demanding vacuum evaporation workflows requiring high source temperatures.
- Explicit electrical loading reference: The 5.31 V, 44 A, 234 W rating provides a clear basis for matching with a heating power supply, reducing risk of electrical mismatch.
Trade-offs
- Strict power supply matching required: The specific voltage and current window (5.31 V, 44 A) means the existing power supply must be precisely capable of delivering this load without over- or under-driving the heater.
- Geometry and wire gauge limit fit: The fixed 3.5×0.75×0.5 in dimensions and 0.025 in wire diameter may not be compatible with all source holders, necessitating physical fit verification before procurement.
