For those who don't know about SMD inductors, when they need to buy or purchase SMD inductors, it is definitely a headache to select them. So today's small series mainly explains what key points need to be understood in selecting SMD inductors, as follows.
(1) inductance and allowable error
Inductance is an important factor of chip inductance. The choice of chip inductance first understands that inductance and error are defined by customers according to the design of circuit board.
(2) rated working current
The rated working current also plays an important role in the circuit. Generally speaking, customers will give data, and other customers will ask for temperature rising current. In practical circuit applications, what customers need is temperature rising current.
(3) DC resistance
The smaller the DC resistance, the greater the current.
(4) Test frequency
Because each customer has different designs, the test frequency is different, and the test frequency is also very important.
(5) Package size
Chip inductor package usually includes chip package and plug-in package. If the package is clearly described in the bill of materials, the possibility of using the wrong materials can be reduced. The packaging form of SMD inductor refers to the description of the shape and size of SMD inductor.
The above content mainly introduces the five key points that should be paid attention to when selecting the chip inductor.
