Overview

The TOXU KC.IG.00154 is a compact round wireless charging coil designed for internal installation in compatible handheld devices, charging equipment and customized inductive power systems.

The coil has a nominal inductance of 6.3uH with a tolerance of +/-10%. Its circular structure measures 35 +/-0.8mm in outer diameter and 5 +/-0.8mm in inner diameter.

A ferrite backing layer is integrated with the coil to support magnetic flux management within the intended wireless charging system. The backing includes self-adhesive material for internal equipment installation.

The complete coil structure has a maximum thickness of 1.6mm including the adhesive layer. Its compact circular design supports integration into equipment with limited internal installation space.

Two 35 +/-3mm connection leads extend from the coil body for connection to a compatible wireless charging circuit.

The engineering drawing identifies KC.IG.00154 as the charging coil installed at the upper housing side of the intended equipment. This installation description does not independently confirm whether the coil operates as a transmitter or receiver.

Final charging performance depends on the charging IC, operating frequency, matching circuit, paired coil, coil alignment, transmission distance, enclosure material and surrounding metal components. Complete-system testing is required before volume production.

System Integration

The KC.IG.00154 is designed for integration with a compatible wireless charging circuit and a properly matched paired coil.

Wireless Charging Coil -> Matching Circuit -> Wireless Charging IC -> Power or Battery Circuit

Before selection, confirm that the nominal inductance of 6.3uH and the mechanical dimensions are compatible with the intended wireless charging IC, matching circuit and paired coil.

The engineering drawing specifies installation at the upper housing side of the intended equipment. The final coil position, orientation and adhesive surface should follow the approved equipment assembly design.

Coil alignment, separation distance, enclosure thickness and nearby metal components can materially affect charging efficiency, temperature rise and overall system stability.

The adhesive surface should be installed on a clean, dry and flat area. The ferrite backing and coil body must not be folded, crushed or subjected to excessive mechanical pressure.

Avoid sharply bending or repeatedly pulling the connection leads during assembly. Mechanical stress may damage the coil winding or lead connection.

The coil must be tested with the actual charging IC, matching circuit, paired coil, enclosure, battery and intended operating conditions before volume production.

FAQ

Q: What is the inductance of KC.IG.00154?

A: The specified nominal inductance is 6.3uH with a tolerance of +/-10%.

Q: What are the coil dimensions?

A: The coil has an outer diameter of 35 +/-0.8mm, an inner diameter of 5 +/-0.8mm and a maximum thickness of 1.6mm including the adhesive.

Q: What backing material is used?

A: The engineering drawing specifies ferrite backing with a self-adhesive structure.

Q: How long are the connection leads?

A: The specified lead length is 35 +/-3mm.

Q: Is this an NFC antenna?

A: No. The supplied engineering drawing identifies KC.IG.00154 as a wireless charging coil rather than an NFC communication antenna.

Q: Is it a transmitter coil or receiver coil?

A: The drawing specifies installation at the upper housing side but does not define the coil as a transmitter or receiver. Its function must be confirmed according to the complete charging system design.

Q: Does it support the Qi wireless charging standard?

A: The available engineering drawing does not specify a wireless charging protocol. Compatibility depends on the charging IC, operating frequency, matching circuit, paired coil and complete-system test results.

Q: What charging power does the coil support?

A: Charging power is not specified in the available drawing. Inductance alone cannot determine the supported charging power.

Q: Can the coil specifications be customized?

A: Inductance, coil dimensions, lead length, ferrite structure and adhesive configuration can be evaluated according to project requirements and order quantity.

Q: Is complete-system testing required?

A: Yes. The coil must be tested with the actual charging IC, matching circuit, paired coil, enclosure and intended operating conditions before volume production.
