SMT & SMD Power Inductor Specifications

 

How to read our online catalogue 1, 2, 3, 4

The code:

1

1. Dimension of body, pitch (the terminal land pattern.).
The size of the body is an important factor but isn't the unique factor.

2. The electrical character:

(1). INDUCTANCE (L: uH): the elementary unit of inductance.

(2) RDC: resistance of Direct current. (Ohms)

It depends on the thickness and length of the wire.
The larger the thickness and the shorter the wire, the lower the resistance.

If we need higher inductance we should wind more turns on the core so the thickness would be smaller and the wire would be longer, so the RDC is larger.

Usually, the higher the inductance, the higher the DCR.
