Fixed inductors are electrical components designed to store energy in a magnetic field when electric current is applied. The CIL21J4R7KNE inductor is a small, surface mountable component intended for use in surface mountted printed circuit boards. It is a surface mountable SMT inductor exclusively developed for low profile mounting on PCBs.

The CIL21J4R7KNE inductor is designed primarily for use in power supply designs. It is suitable for lead-free reflow soldering and has high current capability with low DCR. It has a halogen-free design, which is ideal for power netword designs. The CIL21J4R7KNE has a wide operating temperature range of -40°C to +85°C.

The CIL21J4R7KNE inductor has a 4-pin configuration and a maximum DC current rating of 10A. It measures 21.5 x 27.4 x 9.0mm and has a high inductance value of 4.7 μH. The inductor is designed to provide low losses and a low ESR due to its special composite core geometry. It\'s low profile design helps reduce board space, making it ideal for compact PCB designs.

The working principle of the CIL21J4R7KNE is relatively simple. When current flows through the inductor, it generates a magnetic field, which in turn produces a reverse magnetic field in the inductor. This causes a counter-electromotive force, which is proportional to the rate of change of current. This can be measured with a multimeter to determine the inductance of the inductor.

The CIL21J4R7KNE inductor is a robust and reliable component ideal for use in power supply designs. Its wide operating temperature range makes it suitable for a variety of applications. Its low profile design and high current capability make it an ideal choice for compact PCB designs. Its high inductance value and low ESR makes it a great choice for applications requiring high efficiency power supply designs.
