Fixed inductors have an important role to perform in the powering of a circuit, whether it be for AC to DC converter, DC power supply, or RF communication. The SCMS5D12-3R3 inductor is just one of many available on the market that provides the necessary characteristics and function for many different applications.

The SCMS5D12-3R3 is a shielded power inductor with an inductance rating of 40mH and current rating of 3A. It is designed for use in an industry standard 5mm housing with a 12mm overall size. The inductor features a low DC resistance of 0.036ohms, and a high frequency self-resonant frequency of 11MHz, making it suitable for power conversion and RF applications.

The inductor is designed to minimize the short circuit current, as well as reduce board EM radiation and noise, making it suitable for high density power supplies and boards. The design of the shield ensures reliable operation when battery voltages are fluctuating. The coating also meets UL94V-0 flammability standards, further increasing its durability and viability.

When it comes to applications, the SCMS5D12-3R3 inductor is often used for DC/DC and DC/AC power converters, as well as an RF balun transformer. It is also suitable for motor drives and motion control circuits. The inductor ensures reliable power delivery, and the shield prevents EMI pulsing from leaking out and affecting other components. It is also suitable for slip-ring motor drives, which require EMI shielding to reduce noise.

In terms of working principle, the SCMS5D12-3R3 inductor works much like any other inductor. When a current is passed through the inductor, an electromagnetic field is created, and the inductor stores energy in the form of this field. This energy is then released back into the circuit, helping to maintain a constant current and smooth out any voltage fluctuations.

Due to its ability to store energy, the inductor helps to reduce the size of the circuit, making it more energy efficient and cost effective. The inductor also helps to regulate the current, providing a more consistent and reliable power supply. In addition, the shield helps to reduce EMI noise and interference, making it suitable for systems that require extra protection.

Overall, the SCMS5D12-3R3 inductor is a reliable and durable solution for many power and RF applications. It is designed to provide consistent current and reduce interference, making it suitable for high density circuit boards and power supplies. Additionally, the coating meets UL94V-0 flammability standards, providing it with extra protection and durability.
