This document outlines the product specifications for a watch charging coil manufactured by Dongguan Yinze Electronic Technology Co., Ltd. The coil is designed for use in Apple Inc. products and adheres to specific electrical and material requirements.
The specification details the coil's outline drawing, electrical characteristics (including inductance, DC resistance, and Q factor), and temperature grade. Key parameters such as inductance (L(W1)), DC resistance (DCR(W1)), and Q factor are defined with specific test frequencies. The document also includes a bill of materials, listing the components used in the coil's construction, including the magnetic sheet, twisted wire, glue, and tin. Vendor codes and descriptions are provided for each material.
Furthermore, the document specifies the operation frequency, antenna type, and antenna gain. It also includes remarks on the wire diameter, coil winding, and the placement of the magnetic material. Testing equipment used for evaluating the coil's performance is also listed. The document concludes with a statement regarding the measurement methodology and the inclusion of antenna gain documentation.
