Reliable Φ8 I-shaped Inductor for Industrial Applications

Small build, big role! Introduction to Ferrite E-shaped Inductors Space on the circuit board is precious. Do you need a small inductor to store energy or filter? Φ8 E-shaped inductors are a common choice! Although its diameter is only about 8mm (a little thicker than a pencil lead), the core is a ferrite core inductor. Compared with the air core inductor that has nothing inside, the ferrite core is like the "treasure basin" of the magnetic field, which can provide a greater inductance (coil inductance/ferrite core inductance) in the same small volume. This makes it particularly suitable to be stuffed into places with tight space such as mobile phone chargers, control boards of small household appliances, and LED drivers, serving as a filter or energy storage device. But do remember its Achilles' heel - inductor saturation current! Once the current flowing through exceeds this value, the magnetic core can no longer "hold" more magnetic fields, the inductance will drop sharply, and the c…
