Fixed inductors, including the S0402-10NH3E, are passive electronic components composed of a thickness of coiled wire wound around a core made of a magnetic material, internal insulation, and an external protective complete that encloses both elements. Most fixed inductors used in electrical engineering are simply called coils. The core is normally composed of a solid material like iron. In this way, the core gives a preferential passage to the magnetic flux generated by the electric current that passes through the coil.The S0402-10NH3E is a miniature, molded, low-profile surface mount inductor. It has an applied current range of 0.5 to 2.1 Amps and an inductance range of 8 to 22 nH. It is made of high permeability ferrite core material and features a temperature rise characteristic that ensures a rugged performance in high temperatures. Specifically, the available temperature rating is from -55° C to +125° C with no derating required up to +105° C. It also features high reliability in its construction, which makes it ideal for use in harsh environments such as industrial and military applications.Its applications include motor control, audio systems, automotive, lighting, radio frequency signal conditioning, EMI/RFI filtering, and numerous power supply designs. As for its working principle, it is fairly simple. The passage of an alternating electric current generates a magnetic field inside the fixed inductor by each frequency component of the current. This effect is known as self-induction, and it results in a counter-electromotive force in the circuit that opposes the current change. The greater is the inductance, the greater is the opposition to the current change and, thus, the greater is the energy stored in the inductor, so it can act as a filter and protect other components of the circuit from transients and sharp changes.The S0402-10NH3E has been designed to have a low-profile component height of 0.6 mm, allowing for its use in a wide range of applications requiring tight space constraints. Furthermore, it features good frequency characteristics thanks to its ferrite core material, high temperature stability, increased environmental protection by making use of epoxy resin coating, and Ul94V-0 rating. This makes it the ideal choice for various high performance applications.Finally, the S0402-10NH3E is a reliable and robust fixed inductor that features superior performance in numerous applications in both the consumer and industrial markets. Its low profile, high temperature stability, good frequency characteristics, and environmental protection make it the top choice for a wide range of applications requiring tight space constraints.
