Customized Single Winding PCB 1Coil Wireless Charging Coil 15W/10W/7.5W

1.Product Description

A PCB 1Coil Wireless Charging Coil is a wireless charging component that is designed and fabricated directly on a Printed Circuit Board (PCB). The "1Coil" indicates that it consists of a single coil structure, which simplifies its design and manufacturing process.

This type of charging coil is integrated into the PCB, taking advantage of the PCB's layout and space - saving features. By being part of the PCB, it can be more easily incorporated into the overall circuit design of electronic devices. It functions based on the principle of electromagnetic induction. When an alternating current passes through the coil, it generates a magnetic field. This magnetic field can then induce an electric current in a compatible receiving coil within a nearby device, enabling wireless power transfer.

PCB 1Coil Wireless Charging Coils are commonly used in a variety of small - scale and compact electronic devices. For example, in smartwatches and wireless earbuds, where space is at a premium, the integration of the charging coil into the PCB helps to optimize the internal space utilization. It also reduces the need for additional separate components and complex wiring, contributing to the overall miniaturization and cost - effectiveness of the device. However, compared to multi - coil designs, the single - coil structure may have limitations in terms of charging efficiency over longer distances or with misaligned charging positions. Despite these limitations, its simplicity and space - saving nature make it a popular choice for many applications with specific space and cost requirements.

2.Features

The PCB 1Coil Wireless Charging Coil (PCB Single Coil Wireless Charging Coil) has the following features:
1. Structure and design
-High integration: directly fabricated on the printed circuit board (PCB), it is highly integrated with the PCB without additional coil mounting space, which can effectively utilize the limited space on the PCB and is especially suitable for small electronic devices with very high space requirements, such as smart bracelets, micro medical devices, etc., which helps to realize the miniaturization and thinness of the devices.
--Simple structure: With only one coil, the design and manufacturing process is simpler compared to multi-coil structure, which does not require complex winding and wiring processes, reducing production difficulties and costs, and also reduces the failure points that may be caused by the complex structure, thus improving the reliability of the product.

2.Performance
-Stable electromagnetic induction: working based on the principle of electromagnetic induction, it can stably generate a magnetic field within a certain range, and when the nearby receiving equipment enters its magnetic field range, it can more stably realize the conversion of electric energy to magnetic field energy and then to electric energy, provide continuous charging power for the equipment, and ensure the basic stability of the charging process.
-Good frequency characteristics: at a specific operating frequency, can work well with other components in the wireless charging system, has a good frequency response characteristics, can effectively reduce electromagnetic interference and energy loss, to ensure that the charging process will not produce too much interference with other circuits or equipment, but also to improve its own charging efficiency.

3.Application Advantages
--Good compatibility: The single coil structure is relatively standard and universal, and it is easy to match and be compatible with different types of wireless charging receivers in design, whether it is the common consumer electronic equipment that meets the Qi standard or some customized wireless charging application scenarios, all of them can be adapted to better, and have a wider range of applications.
-Highly cost-effective: Due to the simple structure and uncomplicated manufacturing process, the cost can be significantly reduced in mass production, while its integration on the PCB also reduces the additional assembly cost, making the wireless charging solution using this coil more competitive in the cost-sensitive market, and helping to promote the popularization and application of wireless charging technology in more fields.
