Wireless charging coils can be used to charge and power devices that are within range without the need for a cable connection. WR202020-18M8-G is one of the most popular wireless charging coils. It is a high-efficiency, low-cost wire-free energy receiver that can be used for a variety of both industrial and consumer applications. In this article, we will examine the WR202020-18M8-G wireless charging coil\'s application field and working principle.

The WR202020-18M8-G is a self-resonant planar wireless charging coil with a winding width of 20mm, a winding diameter of 18mm, and a total of 8 turns. It has a high efficiency of 74%, and therefore has a low power loss during transmission. Its high efficiency makes it ideal for applications such as consumer electronics, computer peripherals, home appliances, automotive electronics, industrial automation, smart watches and much more.

The WR202020-18M8-G functions similarly to any other wireless charging coil. It works by using magnetic induction to safely transfer an alternating current (AC) to a receiving coil, generating a magnetic field that induces the electrical current. This wireless charging method eliminates the need for physical cables and ensures safe and secure transfer of energy from a power source to the receiving device.

The magnetic field of the WR202020-18M8-G coil is created by a set of copper coils. This creates a uniform magnetic field that allows for efficient, and accurate transmission of electrical energy. The circular shape of the coil ensures that the magnetic field is evenly distributed within it, which further increases its efficiency and reduces power losses.

The WR202020-18M8-G wireless charging coil\'s operating frequency is typically in the range of 125Khz-265Khz. This frequency is important in determining the power transfer rate that can be achieved with the coil. The higher the frequency, the higher the power transfer rate that can be achieved. This allows for quick charging of devices such as smartphones and other wireless devices.

In order to use the WR202020-18M8-G wireless charging coil, the receiver must be powered and connected to the power source. The coil then begins to generate a magnetic field and sends alternating current signal to the receiving device. This signal is then converted into direct current (DC), which can then be used to power the device.

In conclusion, the WR202020-18M8-G wireless charging coil has a wide range of applications across both consumer and industrial electronics. It is a high-efficiency, low-cost wireless energy receiver that operates at a frequency range of 125Khz-265Khz and is powered by a set of copper coils. Its high efficiency makes it an ideal choice for applications such as consumer electronics, computer peripherals, home appliances, automotive electronics, industrial automation and more.
