ESD Notch Filters: The product portal has been released.

ESD notch filters from TDK combine electrostatic discharge protection and noise suppression. The main component is a varistor material commonly used for ESD protection, making it possible to reliably protect electronic circuits from electrostatic discharge. Proprietary materials design and structure design realize outstanding attenuation for a given frequency, enabling highly effective noise suppression. Low audio distortion (THD+N/total harmonic distortion+noise) is advantageous in audio lines (such as for earphones, microphones, and speakers), and the components are highly effective to counter burst noise (TDMA/TDD) and for measures related to reception sensitivity. Ideal for audio equipment designed for high sound quality.

Hybrid Polymer Capacitors: The product portal has been released.

In this type of capacitor, a combination of a highly conductive polymer and a liquid electrolyte is used instead of a liquid electrolyte, which has a relatively low conductivity. This means a significant reduction in the ESR (Equivalent Series Resistance), so that – depending on the type – values in the single-figure milli-ohm range are achieved. This in turn means that a very high ripple current can be applied to these capacitors. As a result, in many designs – especially in automotive electronics – a parallel connection of capacitors is no longer required, which saves space and increases reliability. TDK currently offers axial, soldering star and SMD hybrid polymer aluminum electrolytic capacitors.
