	CB2012T2R2M: A Dependable SMD Inductor for Power and Signal Management

	The CB2012T2R2M is a high-quality surface mount device (SMD) inductor engineered to deliver exceptional stability, superior performance, and reliable operation in a wide range of electronic circuits. With an inductance value of 2.2 μH (directly indicated by "2R2"), this component is designed to meet the rigorous demands of power filtering, energy storage, and signal conditioning across diverse industries.

	Key Technical Specifications

	The CB2012T2R2M features a precisely calibrated 2.2 μH inductance, optimized for medium-frequency and low to medium-power applications. Housed in a compact 2012 (2.0mm x 1.2mm) surface-mount package, it offers a space-efficient solution for printed circuit boards (PCBs) of varying densities, enabling seamless integration into consumer electronics, industrial controls, and automotive systems. This inductor utilizes high-quality ferrite core material, ensuring low DC resistance (DCR) to minimize power loss and excellent temperature stability. The "M tolerance" (±20%) provides consistent inductance values for general-purpose applications, while its robust construction enhances solderability and mechanical durability. It operates reliably across a temperature range from -40°C to +125°C, making it suitable for harsh environments.

	Notable Performance Advantages

	This SMD inductor excels in power management circuits, offering superior energy storage capacity to handle transient currents and maintain stable power delivery. Its ferrite core design provides effective noise suppression, reducing electromagnetic interference (EMI) in sensitive circuits such as audio devices and communication modules. The CB2012T2R2M also demonstrates excellent frequency response, maintaining stable inductance across a broad range of operating frequencies-critical for applications like DC-DC converters and voltage regulators. Additionally, its compact size supports the miniaturization of electronic devices, and its RoHS-compliant construction adheres to international environmental standards.

	Versatile Applications Across Industries

In consumer electronics, the CB2012T2R2M enhances power stability in smartphones, tablets, and portable chargers, ensuring consistent performance and extending battery life. In the automotive sector, it plays a key role in in-vehicle infotainment systems, sensor modules, and powertrain controls, reliably operating under extreme temperature and vibration conditions. For industrial electronics, this inductor optimizes performance in motor drives, power supplies, and automation equipment, reducing energy loss and improving system efficiency. It also contributes to telecommunications, supporting signal integrity in routers, modems, and 5G small cells.
