Industrial-Grade Air Core Inductor Coil, 86 x 30.5 x 14 mm Rectangular Hollow Winding, Litz Copper Wire, Tab or Lead Wire Terminals

Industrial-Grade Air Core Inductor Coil for Microwave Ovens

This is a rectangular air core inductor coil designed for microwave oven equipment. The coil is wound with litz copper wire, has no magnetic core inside, and is wrapped and secured with high-temperature-resistant insulating material on the outside. It can be configured with tab terminals or insulated lead wires depending on the mounting requirements. The displayed specification measures approximately 86 × 30.5 × 14 mm, making it suitable for microwave oven projects that require a rectangular mounting space and customized electrical parameters.

Product Features

• Microwave Oven Application: Designed to match the mounting space, connection method, and electrical parameters of microwave oven equipment.
• Air Core Structure: No magnetic core is used inside the winding, avoiding core saturation issues. Actual performance is determined by the coil's geometric dimensions, number of turns, conductor cross-sectional area, and operating frequency.
• Litz Copper Wire Winding: Parallel-stranded litz copper wire construction balances conductivity, winding profile, and assembly requirements.
• Rectangular Shape: The displayed specification measures approximately 86 × 30.5 × 14 mm with rounded corners, making it easy to fit within the internal space of the equipment.
• Two Termination Options: Available with tab terminals or insulated lead wires for convenient connection to microwave oven wiring harnesses and assembly systems.
• Customization Supported: The winding design can be adjusted based on target inductance, test frequency, DC resistance, current, temperature rise, and mounting dimensions.

Structure and Terminals

The coil features a hollow rectangular winding with insulating spacers on the long sides and high-temperature-resistant tape securing the corners. The tab terminal version uses mounting brackets to expose the tabs for quick assembly; the lead wire version can be configured with custom wire length, color, insulating sleeves, and connectors as required by the project. Terminal configuration should be based on customer drawings or samples.

Reference Specifications

Information Required for Customization

To confirm the microwave oven coil solution, please provide: target inductance and test frequency, maximum DC resistance, operating current and peak current, operating frequency, allowable temperature rise, mounting space, terminal or lead wire requirements, ambient temperature, samples or drawings, and estimated order quantity. Once parameters are received, wire gauge, number of strands, number of turns, dimensions, and termination structure can be further confirmed.

FAQs

Can this air core inductor coil be used directly in all microwave ovens?

No, it cannot be universally applied based on dimensions alone. Different microwave oven projects may have different inductance, current, frequency, temperature rise, terminal, and mounting space requirements. Electrical parameters and drawings must be verified before replacement or mass production.

Can customization be done based on an existing sample?

Yes. Evaluation can be performed based on samples, 2D drawings, or key dimensions, combined with inductance, DC resistance, and current requirements to determine the winding design.

Can the terminals or lead wire length be changed?

Yes. Tab specifications, lead wire length, wire color, insulating sleeves, and connectors can all be confirmed according to assembly requirements.

What are the most important parameters for a quotation?

Please provide at least the inductance and test frequency, operating current, DC resistance, dimensional constraints, and termination method. For replacement projects, it is recommended to also provide the original sample or complete drawings.
