The difference between I-shaped inductors and color ring inductors

I-shaped inductors are generally composed of magnetic cores or iron cores, skeletons, winding groups, sleeves, packaging materials and other parts. Its production is generally on the I-shaped inductor core. We wind the coil according to the different parameter requirements of customers and lead out two pins. The inductor made in this way is called an I-shaped inductor. Under normal circumstances, the I-shaped inductor has two pins, but according to the production needs of customers, there are also I-shaped inductors with three pins. I-shaped inductors are a type of plug-in inductors. We can identify it well from the appearance, it looks like a "I" character. The color ring inductor has an obvious feature in terms of appearance. It has two pointed ends, a large middle, and gradually becomes thinner from the place where the leads are connected to both sides.
Product features of I-shaped inductors:
1. High power and high magnetic saturation;
2. Low impedance, small size, small space occupation;
3. High Q factor, small distributed capacitance;
4. High self-resonance frequency; special guide pin structure, not easy to produce closed circuit phenomenon;
5. PVC or UL heat shrink tubing is generally used to protect the outside. I-shaped inductors are suitable for: computers, power equipment, DC/DC conversion, etc.
Color ring inductors have the following 5 characteristics:
1. The color ring inductor has a solid structure, low cost, and is suitable for automated production.
2. Special core material, high Q value and self-resonance frequency.
3. The outer layer is treated with epoxy resin for high reliability.
4. The inductance range is large and can be automatically plugged in.
5. Lead-free and environmentally friendly.
Functions of color ring inductors:
1. Choke coil
2. RF use
3. Peaking coil
In short, the existence of color ring inductors can widen the inductance range, high Q and SRF values, and extend the service life of the product. Applications include VCR, TV, CRT, stereo, radio, disk drive, industrial electronics, LED lighting, smart home, etc.
