How to judge the quality of integrated inductance

How to judge the quality of integrated inductance

Good or bad judgment: The reading of the chip inductance at this time should be zero, and if the multimeter reading is too large or infinite, the inductance is damaged.

Introduces the inductance stability of inductors

Introduces the inductance stability of inductors

Inductance refers to the strength of the current that can be induced by the coil when it is active in the magnetic field, and the unit is "Henry" (H). Also refers to the application of this property made of components. Inductance is the electromagnetic induction characteristic presented by the inductor in the circuit! (including self-inductance and mutual inductance), the coil is an inductive element. Broadly speaking, inductance exists in the circuit, any component is not only the coil has inductance! In a sufficiently high frequency circuit, any component line will have an inductance effect. Correctly speaking, the coil is an inductor, and the main component of the inductor is the coil.

What is the use of inductors and how to distinguish

First, choke: used to block low-frequency alternating current in low-frequency circuits; Pulsating direct current to pure direct current circuit; It is commonly used in the middle of two filter capacitors at the output end of the rectifier circuit, and the choke and capacitor form a Π filter circuit. In the high frequency circuit: is to prevent the high frequency current flow to the low frequency end, in the old regenerative radio high frequency choke; Be applied.

Identification and detection methods of common inductance types

Identification and detection methods of common inductance types

There are many kinds of inductors, different shapes, the more common are: single-layer flat wound hollow inductors, interwound hollow inductors, empty core coil, multi-layer hollow inductors, honeycomb inductors, inductors with magnetic core, magnetic tank inductors, high frequency choke, low frequency choke, fixed inductors and so on.

How about the production process of the shape structure of the laminated chip inductor?

How about the production process of the shape structure of the laminated chip inductor?

Laminated ferrite inductors are inductors with a multilayer structure similar in shape to ceramic chip capacitors. The size of this kind of chip inductance can be small, small package can be 1.0*0.5*0.5mm (length, width and height), large size laminated inductance can be 330uH, and its substrate is ferrite material.

Does the winding direction of high-power inductors affect the inductance?

Does the winding direction of high-power inductors affect the inductance?

If the structure of the high-power inductor is not completely symmetrical, the characteristics of the high-current chip inductor manufacturers will be different in the packaging direction. Therefore, in order to make the product give full play to its due characteristics during use, the product is often marked with marks to indicate its directivity.
