Vishay Boosts Wireless Power Reliability for Industrial Use

When electronic devices require efficient and stable wireless power transfer amid extreme temperature fluctuations or complex electromagnetic conditions, conventional charging components often fall short. The reliability of wireless charging technology hinges on the precision design of coils and shielding components.

Receiver Side: Compact Design and Temperature Resilience

Wireless receiver coils are critical determinants of charging efficiency and spatial configuration. The receiver product line has been extensively optimized for various size requirements and thermal management needs:

• 3010 and 4532 series: Engineered for compact devices, these maintain exceptional inductance stability across a broad temperature range from -40°C to +85°C.
• 3222, 3827, and 4832 series: Enhanced material processing elevates the temperature tolerance ceiling to +105°C, effectively addressing thermal challenges during high-load charging while maintaining operational efficiency during prolonged use.

Transmitter Side: Industrial-Grade Protection and Power Delivery

As the power source, transmitter coil durability directly impacts system longevity. The transmitter series prioritizes both power density and environmental adaptability:

• Core performance series: The 4646 and 5547 series support operational environments up to +105°C, meeting requirements for most industrial and consumer applications.
• Special protection series: The 5050 series incorporates environmental shielding to withstand physical and chemical degradation in harsh conditions, with temperature resilience from -40°C to +105°C.
• High-temperature extreme series: Designed for demanding industrial environments, the 9955 series and select premium models push thermal limits to +125°C, maintaining precise resonant frequency and energy transfer efficiency even in high-temperature, high-pressure conditions.

All coil components undergo rigorous electrical performance testing and are accompanied by comprehensive technical documentation, providing engineers with reliable data for circuit simulation, thermal analysis, and electromagnetic compatibility design. Whether developing portable electronics or industrial automation systems, these wireless charging components offer solutions for building high-performance, long-lasting power systems.
