Fixed inductors are components that are designed to exhibit a fixed and unchanging inductance across a range of currents and wide temperature variation. The SCEP147S-3R4 is a ceramic-based, fixed inductor designed to operate at frequencies up to 200kHz and current ratings up to 7A. It is usually used in power supplies, DC/DC converters, and switching applications, and can be found in motor control, industrial automation, and automotive applications.

The basic principle of operation of a fixed inductor is that when a current is passed through a wire, it creates a magnetic field around the wire. This magnetic field can be used to store energy; the energy increases as the current rises and decreases as the current decreases. The more turns in the wire, the more energy it can store. The inductance of a given fixed inductor is measured in henries (H); the more turns in the wire, the higher the inductance.

The SCEP147S-3R4 is specifically designed to provide that inductance in a compact size, with a footprint of just 7.3mm x 6.7mm x 4.7mm. It also has a maximum DC resistance of 0.170Ω, so it can handle higher currents without having its insulation damaged. Additionally, it can operate over a wide temperature range, from -55°C to +125°C, making it suitable for both better and harsher environments.

In terms of its applications, the SCEP147S-3R4 is best suited for resonant circuits, DC/DC converters, electronic ballast, and motor control applications. It can also be used as an energy storage device for high power amplifiers and as an EMI filter in automotive and industrial applications. Furthermore, it is suitable for high reliability, consumer, and demanding applications where the inductors need to operate reliably over a wide temperature range.

The SCEP147S-3R4 has many advantages, including its small size, high current handling ability, and wide temperature range. It also has excellent anti-surge and damping characteristics, making it suitable for demanding applications. Additionally, its high stability also makes it a reliable long-term solution. It is also relatively inexpensive for its size and performance, making it an attractive option for those looking for a cost-effective solution.

The SCEP147S-3R4 is a versatile and reliable fixed inductor that is well suited for a wide range of applications. It has a wide temperature range, excellent current handling capability, and low cost making it a great choice for many applications. With its small size, excellent stability, and high reliability, the SCEP147S-3R4 can be used in many high-reliability applications.
