Fixed Inductors are a crucial component for electric current control in electrical and electronic circuits. They can be used for many purposes like filtering, resonant steps, frequency regulation, etc. The Murata SCRH74B-100 is a fixed inductor from Murata Electronics. It has a nominal inductance of 100uH and can handle current up to 3.6 A. DesignThe SCRH74B-100 is designed as a cylindrical tube with the body being made of a ferrite material. The windings are enamel coated copper wire. The internal construction features multiple windings wound in an overlapping fashion. The lead out terminals are made from brass with a nickel plated finish.ApplicationThe SCRH74B-100 is a versatile part and can be used in a variety of applications. It can be used to create filters and impedance matching networks. It can also be used in power supplies, switching converters, and EMI filters.Working PrincipleThe SCRH74B-100 is a fixed inductor and works by creating a magnetic field when electric current passes through it. The electrical resistance of the inductor is proportional to the amount of current passing through it. The magnetic field created by the SCRH74B-100 then works to oppose the incoming current. This results in the inductor limiting the amount of current passing through it. At the same time, the inductor is able to store the energy of the current as magnetic energy and then release it back to the circuit when current is reduced or stopped. This ability to store energy is why inductors are used in a variety of applications.AdvantagesThe SCRH74B-100 offers the user a number of advantages. It is small size allows it to be used in tightly packed circuit boards. The ferrite material used in the body also makes the part rugged and reliable. Additionally, the SCRH74B-100 can handle a high amount of current, up to 3.6 A. This makes it suitable for applications that require high amounts of current.DisadvantagesThe SCRH74B-100 has some potential disadvantages as well. Most notably is its price, as it is more expensive than other similar inductors. Additionally, the inductor may be sensitive to temperature changes and can be damaged if exposed to high temperatures.ConclusionOverall, the Murata SCRH74B-100 is a versatile and reliable fixed inductor. It has a nominal inductance of 100uH and can handle current up to 3.6 A. It can be used for a variety of applications such as filter creation, impedance matching, power supplies, converters, and EMI filters. Its advantages include its small size, ruggedness, and its ability to handle high current. Its potential disadvantages include its price and sensitivity to temperature changes.
