Wireless Charging WRM483245 Series

Product catalog summary

Overview: The document details the specifications and features of the WRM483245 series wireless charging receiving modules, specifically models WRM483245-15F5-5V-G1 and WRM483245-15F5-5V-G2. These modules are designed to provide a 5V x 1A output and are fully compliant with WPC standards. They feature a pre-cracked ferrite for durability and are available in a flexible sheet type with a maximum thickness of 1.0mm for the G2 model.

Specifications: Both models have a maximum coil thickness of 1.00mm and module thickness of 1.80mm for G1 and 1.00mm for G2. They offer an inductance of 13μH and a DC resistance of 0.27Ω at 25°C. The output voltage ranges from 4.95 to 5.05V with an output current of 0.3 to 1.0A, achieving an efficiency of 72%. The modules use the TC7763WBG IC from Toshiba.

Electrical Characteristics: The modules have specific dimensions (W1: 32mm, L1: 48mm, L2: 28mm) and an I/O configuration with three pins: Vchar IN, GND, and WC-EN.

Usage Guidelines: The document advises against using or storing the modules in corrosive environments and emphasizes the importance of preheating components before soldering to avoid temperature differences exceeding 150°C. It warns against overheating, which can lead to short circuits or reduced performance.

Application Limitations: The modules are intended for general electronic equipment and are not designed for high-safety or high-reliability applications such as aerospace, medical, or military equipment. Users with special requirements should contact the manufacturer.

Contact Information: The document provides contact details for representatives in various regions, including the US, EU, Japan, TTW, China, Korea, and ASEAN.

REMINDERS Do not use or store in locations where there are conditions such as gas corrosion (salt, acid, alkali, etc.). Before soldering, be sure to preheat components. The preheating temperature should be set so that the temperature difference between the solder temperature and product temperature does not exceed 150°C. Soldering corrections after mounting should be within the range of the conditions determined in the specifications. If overheated, a short circuit, performance deterioration, or lifespan shortening may occur. Self heating (temperature increase) occurs when the power is turned...
