Reinforced THT Inductor PFC UPS Chargers

Product Overview

The 2504 THT High Current Inductor is a high-performance through-hole magnetic component designed for high-power electronic systems, featuring a mechanically reinforced shielded high current inductor structure and ultra-low DC resistance (RDC). As a core energy storage and filtering component, this 2504 HCF THT inductor is optimized for high current power conversion and energy storage scenarios, with a shielded magnetic design that minimizes electromagnetic interference (EMI) and a mechanically reinforced shell that enhances structural stability in vibration-prone industrial environments. With inductance values ranging from 1μH to 10μH, high rated current (up to 39A) and excellent saturation current performance, the 2504 ultra-low RDC THT inductor is the ideal choice for power supply manufacturers, new energy equipment developers and industrial electronic solution providers, widely applied in high current power supplies, solar inverters and power factor correction (PFC) circuits.

Core Advantages

Mechanically Reinforced Structural Stability

Adopting a one-piece mechanically reinforced molding process, the 2504 THT High Current Inductor has high structural rigidity and vibration resistance, effectively preventing coil loosening and magnetic core damage in harsh industrial environments such as factory equipment and vehicle-mounted power supplies. Its through-hole (THT) welding design ensures firm soldering with the PCB board, reducing contact resistance and improving the reliability of long-term operation.

Shielded Magnetic Structure for Low EMI

Equipped with a fully enclosed shielded magnetic core structure, the inductor effectively suppresses magnetic flux leakage, reduces EMI interference to surrounding components and avoids external magnetic field interference to its own performance. This design meets the EMC requirements of industrial electronic products, simplifying the EMI debugging process of customer products.

Ultra-Low DC Resistance (RDC) for High Efficiency

Utilizing high-conductivity copper wire and optimized coil winding design, the inductor achieves ultra-low DC resistance, significantly reducing I²R power loss during high current operation. This not only improves the energy conversion efficiency of power supply systems but also reduces component heating, extending the service life of the entire circuit system.

High Current Handling & Low Saturation Loss

With high rated current (1μH model up to 39A) and 30% saturation current (up to 33A), the 2504 THT High Current Inductor maintains stable inductance performance under high current load, avoiding inductance drop caused by magnetic saturation and ensuring the stability of power conversion and filtering circuits. Its high self-resonant frequency (up to 38MHz) adapts to high-frequency power conversion designs, expanding the application range of the product.
