1、 Difference

1. Different working principles

Ordinary capacitors play a role in storing electricity in circuits, that is, storing charges through the dielectric between the two plates (such as aluminum oxide, polyimide, etc.), thereby achieving the conversion and transmission of electrical energy. However, non inductive capacitors utilize the induction effect of electromagnetic fields to achieve capacitive impedance, so they do not have energy storage capacity in the circuit.

2. Different energy transmission methods

There are also significant differences between ordinary capacitors and non inductive capacitors in terms of energy transmission methods. The former conducts electrical energy through the movement of charges in the dielectric, while the latter achieves energy transmission through electromagnetic field induction.

3. Different usage scenarios

Due to the differences in their working principles and energy transfer methods, they also have different scenarios in practical applications. Ordinary capacitors are suitable for situations that require energy storage or have frequency selectivity, such as filtering, tuning, etc. Non inductive capacitors are more suitable for applications that require capacitive impedance and energy transmission, such as wireless communication, magnetic levitation, and other fields.

2、 Application examples

1. Application of ordinary capacitors

In electronic circuits, ordinary capacitors are widely used in LC filter circuits, tuning circuits, voltage stabilizing circuits, amplification circuits, etc. In communication systems, ordinary capacitors are also widely used for signal adjustment, waveform shaping, RF tuning, noise reduction, and more.

2. Application of non-inductive capacitors

Non inductive capacitors are widely used in the control system of maglev trains, which can maintain stability during high-speed driving. Meanwhile, in wireless communication, inductive capacitors are also widely used, such as LC resonant circuits, matching circuits, etc.

3、 Summary

In summary, there are significant differences in the working principle, usage scenarios, and performance characteristics between non inductive capacitors and ordinary capacitors. In practical applications, selecting different types of capacitors should be based on actual demand scenarios to achieve optimal results.
