In the evolution of power inductors, miniaturization is an inevitable trajectory. Yet, miniaturization often confronts the challenge of meeting the demands for higher power and lower Direct Current Resistance (DCR) in devices. Personal electronics are becoming lighter and thinner, ranging from smartphones and smartwatches to tablets, ultra-thin laptops, solid-state drives, the new DDR5 memory, and compact DC-DC modules, all of which require inductors with smaller dimensions and thinner profiles. Additionally, the advent of more powerful chips and feature-rich devices underscores the need for inductors with higher saturation currents and even lower DCR.
Cjiang Microelectronics shines in addressing challenges in the industry. This is where the brand demonstrates its strength, paving the way for innovative products that meet market demands. In 2021, the company introduced the FTC series infused with T-CORE+ flat wire technology and the FEXL series. Specifically, the FTC series, targeting handheld smart devices, continuously innovates to meet customer needs. To date, Cjiang has released over 20 diverse product sizes encompassing hundreds of models.
