　　 1. Core Product Information: Standardized configuration, tailored to meet mainstream needs.

　　As the core standard product in the Changrui circular common-mode inductor series, the CR1346’s parameter configuration precisely meets the mainstream demands of the power adapter industry. Specific details are as follows:

　　Material Code: CR1346
　　Specification Model: T9X5X3-220uHmin
　　Core parameters: Green manganese-zinc material (dimensions: 9×5×3 mm), inductance ≥220 uH (under 1 kHz, 0.25 V conditions), internal resistance 30 Ω, wire diameter 0.6×6.5 TS, CR structure design, 6.5 turns, pin pitch 4.5×4.5 mm, pin length 3.5 mm.
　　Core feature: An innovative structure replaces the traditional glue-fixing and base-mounting processes, delivering exceptional cost-effectiveness.

　　Standardized parameter settings, combined with mass production, ensure product consistency and reliability. Meanwhile, the product design precisely matches today’s most popular power ranges, covering output currents of 2 A, 2.5 A, and 3 A—this is precisely the core foundation that makes it the preferred choice for general-purpose components.

　　 II. Behind 13 Million Units Sold: Three Core Advantages That Have Earned Customer Trust

　　To become a blockbuster with sales of 13 million units, CR1346 didn't rely on luck—it relied on precisely addressing customer pain points and delivering solid, robust product capabilities.

　　1. Ultimate cost-effectiveness and delivery: In addition to effectively suppressing electromagnetic interference and ensuring stable adapter operation, this solution also meets customers’ pursuit of ultimate cost-performance. Meanwhile, its standardized dimensions and parameters perfectly match the assembly requirements of most mainstream power adapters, eliminating the need for customers to place additional custom orders and significantly shortening the delivery cycle.

　　2. Hardcore quality lays a solid foundation of trust: We partner with premium-quality magnetic core suppliers, and our automated production line ensures that every single product meets its designed electrical specifications. Our own Longrui manufacturing facility meticulously oversees every stage of the production process—from raw material procurement to finished-product shipment—implementing rigorous quality controls at each step to guarantee stable production capacity and consistent product quality, giving customers greater peace of mind when placing orders.

　　3. Verified customer testimonials: Thanks to its outstanding performance and reliable supply, the CR1346 has become the preferred choice for over 30 power adapter manufacturers. Feedback from a leading power adapter supplier: “The CR1346 is readily available in stock, and we’ve been cooperating with this supplier for many years without ever encountering any quality or delivery issues. It has been added to our standard product library, and we prioritize it when developing new products.”

　　 III. Application Scenarios and Value: Beyond Power Adapters—Endless Potential

　　In addition to its core application in power adapters, the CR1346, with its excellent common-mode rejection capability and standardized configuration, can also be adapted to various electronic device applications that require electromagnetic interference suppression, such as:

　　1. Small switching power supply: Enhances power conversion efficiency and ensures stable power operation;
　　2. Charger equipment: Suppresses electromagnetic interference during the charging process and ensures charging safety;
　　3. Other electronic control modules: Provide a stable electromagnetic environment for module operation.

　　For our customers, choosing CR1346 means opting for a triple guarantee: “high cost-effectiveness, stable quality, and rapid delivery.” For our internal partners, the success of this product also underscores the strong market potential of high-quality standard products—precise market positioning, standardized production and promotion can enable commodity-grade materials to quickly gain market acceptance while optimizing the company’s capacity structure and reducing operational costs.
