Fixed Inductors are one of the most commonly used electronic components in the market. The SRP7028A-2R2M is a high performance fixed inductor developed by Murata, a leader in the field of inductor technology. In this article, we will discuss the application field and working principle of the SRP7028A-2R2M.

The SRP7028A-2R2M is a cylindrical-shaped inductor made of ferrite core material. It is designed to provide high-current capacity along with stable inductance and low resistance. This makes it ideal for high frequency applications such as in power supply circuits, switching circuits, and pulse amplification. It has a wide range of inductance values, from 1.3nH to 470nH, as well as operating temperatures ranging from -40°C to +125°C.

The core material of the SRP7028A-2R2M is formed from two ferrite rods that are held in place with a conical copper coil. This ferrite-copper combination produces an inductor with a high current capacity, low flux leakage, and low resistance. It is also capable of withstanding high temperatures up to 125°C without compromising its performance.

The SRP7028A-2R2M features a high self-inductance, which helps to limit the peak voltage induced from a changing input current. This self-inductance also helps to reduce the power output ripple caused by switching frequencies. The SRP7028A-2R2M also offers a high surge current capacity, up to 150% of its rated current, enabling it to handle high surge power conditions.

The SRP7028A-2R2M is suitable for a variety of applications including power supply regulators, switching converters, DC-DC converters, inverters, and other digital circuits, as well as high-speed transmissions for automotive electronics. Its combination of high current capacity, low resistance, and stable inductance makes it well suited for use in DC-to-DC converters and switching converters, where it is used to minimize the output ripple from transistors and ICs.

In power supply circuits, the SRP7028A-2R2M is used as an inductor to filter spikes in input current. It helps to reduce the amount of power dissipation in the circuit due to its low resistance. In switching converters, it helps to minimize the switching losses and output voltage spikes caused by the switching of the transistors.

The SRP7028A-2R2M also features a low resistance, allowing for high currents to flow without generating heat. This reduces power dissipation in the circuit, helping to prolong the life of the component. Its high inductance also provides protective benefits, helping to reduce the effects of fluctuations in the current or voltage which can damage sensitive components.

In summary, the SRP7028A-2R2M is a high performance fixed inductor designed to provide high current capacity, low resistance, and stable inductance. Its combination of these qualities make it suitable for a variety of applications where high performance is needed, including power supply circuits, switching converters, and DC-to-DC converters. Its low dissipation and low resistance characteristics help to reduce power consumption and protect sensitive components from damaging current levels.
