Fixed Inductors

Fixed inductors are basic parts that are used to store a magnetic field. They are also known as chokes and are a crucial component of electronic circuits and devices. They help to regulate the flow of electricity from one component to another. Fixed inductors are used in a variety of applications, from radio antennas to power management devices. One such type of inductor is the SRP1770TA-220M. This article will discuss the application field and working principle of the SRP1770TA-220M.The SRP1770TA-220M is an axial lead, low-profile, surface mount fixed inductor with a maximum current rating of 220mA. It has a very low DCR value of 0.07Ω and a high inductance value of 17.7uH. The inductor is designed to operate at temperatures ranging from -40°C to 105°C. It also features a shielding design which helps to improve its noise immunity.The SRP1770TA-220M is mainly used in switching-mode power supplies, DC-DC converters, low-accuracy voltage regulators, LED lighting, and various mobile electronic devices. It is suitable for various power management circuits such as battery chargers, family appliances, electric tools, and even automotive electronics. In most cases, the SRP1770TA-220M is used in circuits where a low DCR and high inductance values are required.The SRP1770TA-220M works on the principle of electromagnetic induction. When current flows through the inductor, it creates a magnetic field around it. The magnetic field interacts with the rotating magnetic field of the current, inducing a voltage across the inductor and providing it with the property of inductance.The SRP1770TA-220M is especially useful for applications where a low-profile inductor is needed. This is because the SRP1770TA-220M is one of the smallest inductors on the market, with its height being only 2.4mm. It also has a relatively low price when compared to other similar components.Overall, the SRP1770TA-220M is an excellent choice for various electronic applications where low DCR values and high inductance ratings are required. It is ideal for power management circuits such as switching-mode power supplies and DC-DC converters, and its small size makes it suitable for many mobile devices. With its low price and high quality, the SRP1770TA-220M is a highly recommended component for any application.
