How to reduce acoustic noise of MLCCs in power applications

Some applications can use electrolyte or tantalum-type capacitors, preferably thru-hole types when acoustic noise is problematic. But for applications that are more cost-sensitive or size-constrained (such as personal electronic devices), you cannot avoid thin, small ceramic capacitors, and the need to reduce noise immediately becomes critical.

6 FAQs about [AC absorption capacitor makes noise]

Why does a ceramic capacitor make a noise?

The expansion and contraction (vibration) of the ceramic capacitor is conveyed to the circuit board, causing it to vibrate. This can produce an audible sound when the vibration frequency is within the range of human hearing (20 Hz to 20 kHz). This phenomenon is referred to as the emission of “acoustic noise” by the ceramic capacitor.

What is noise management using capacitors?

Noise management using capacitors makes use of their characteristics of high impedance in low-frequency ranges and low impedance in high-frequency ranges. A capacitor is connected between a power supply line and grounding to prevent noise propagation to the subsequent circuit (Load side) by passing the noise to the grounded side.

Are ceramic capacitors a good choice for acoustic noise?

Capacitor manufactures have already developed ceramic capacitors with low distortion dielectric material, which exhibit lower ferroelectric properties and smaller deformation in regards to a voltage change. And there is a series manufactured by Murata that the capacitor is on interposer substrate to reduce the acoustic noise (Figure 2).

Do capacitors reduce noise?

Capacitors, in particular, store electric charges, but they also play a major role in noise reduction. As digital devices become smaller and handle higher frequencies, the low-ESL and low-ESR types of bypass capacitors and decoupling capacitors are becoming more prevalent. Noises have colors? Noises have colors?

Can a capacitor remove noise from an IC?

When noise enters a DC current flowing inside an electronic circuit, voltage fluctuations could occur, leading to IC malfunctions. To deal with this, capacitors are widely used to remove noise. This is because a capacitor functions as the simplest noise filter by blocking DC current while allowing noise to pass.

Do capacitor leads cause spike noise?

Line inductance, including capacitor leads, may generate spike noises and therefore need to be minimized (= Wiring (leads) need to be short). Ripple noise included in the output voltage of switching power supplies is an important noise to be suppressed in electronic circuits.
