CM453232-2R2KL: Redefining Power Inductor Performance

The CM453232-2R2KL emerges as a cutting-edge power inductor, meticulously engineered to deliver unrivaled energy efficiency, superior thermal stability, and exceptional reliability in modern electronic circuits. With an inductance value of 2.2 μH (denoted by "2R2"), this component sets new standards for power conversion, signal filtering, and energy storage across diverse applications.

Precision-Engineered Technical Specifications

The CM453232-2R2KL features a precisely calibrated inductance of 2.2 μH, optimized to meet the demanding power management needs of complex systems. Housed in a robust 4.5mm x 3.2mm x 3.2mm surface-mount package, it balances compact design with sturdy construction, making it ideal for high-density PCBs in space-constrained devices. This inductor boasts a high saturation current rating, enabling it to handle significant electrical loads without performance degradation, while its low DC resistance (DCR) minimizes power losses, enhancing overall circuit efficiency. The K tolerance level (±10%) ensures consistent inductance values, and the advanced magnetic core material provides excellent temperature stability across -40°C to +125°C, maintaining reliable operation in extreme environments.

Outstanding Efficiency and Performance Advantages

This power inductor excels in high-frequency power conversion applications, offering excellent impedance characteristics that suppress electromagnetic interference (EMI) and maintain signal integrity. Its high-quality factor (Q-factor) reduces energy loss during power switching, crucial for extending battery life in portable devices and improving system efficiency in power-hungry electronics. The CM453232-2R2KL also demonstrates superior thermal conductivity, dissipating heat effectively to prevent performance degradation under continuous high-load conditions. Additionally, its lead-free and RoHS-compliant design aligns with global environmental standards, supporting sustainable manufacturing practices.

Versatile Applications Across Industries

In consumer electronics, the CM453232-2R2KL optimizes power delivery in smartphones, tablets, and laptops, enhancing battery performance and system stability. In the automotive sector, it plays a critical role in engine control units (ECUs), advanced driver-assistance systems (ADAS), and electric vehicle powertrains, ensuring reliable operation amid vibrations and temperature fluctuations. For industrial electronics, the inductor stabilizes power flow in programmable logic controllers (PLCs), motor drives, and industrial automation equipment, reducing downtime and boosting productivity. Moreover, in telecommunications and networking, it filters noise in 5G base stations and high-speed routers, enabling seamless data transmission with minimal signal distortion.
