This paper investigates the nonlinearity of capacitors and suggests improved tradeoff between ESD protection and data bandwidth by using the Antiferroelectric (AFE) capacitors as ESD protection. The dielectric constant of AFE material increases with increasing voltage. The voltage dependence of X7R and AFE capacitors are measured using static

Customer ServiceThere are some chip capacitors made specifically to absorb ESD (electrostatic discharge) events, but typically "ESD caps" are nothing more than regular chip capacitors placed directly at a connector of a PCB whose primary purpose is to absorb ESD events that occur at the connector before they make their way further on to the PCB to potentially damage
Customer ServiceWhen higher levels of protection are required, external components such as Y-capacitors and gas discharge tubes (GDT) can be used to attenuate and dissipate energy from a discharge. While they provide extra protection, these external solutions may also increase board size and introduce operational constraints, increasing costs.
Customer ServiceThe maximum charge a capacitor can hold largely depends on the dielectric material inside. That material is the enabler for the performance. Ongoing development in fields such as high-power electronics, renewable energy, hybrid electric vehicles and electric aircraft, is posing an urgent need for more advanced electrostatic capacitor technology

Customer ServiceMultilayer ceramic capacitors (MLCCs) are one of the solutions used to protect components from ESD damage. Since integrated circuits (ICs) are most prone to damage by ESD, MLCCs are placed close to the board connection contacts or directly next to the IC connections in order to absorb and then level the unwanted voltage spikes.
Customer ServiceIn the third installment of this series, I explored the importance of the clamping voltage of an electrostatic discharge (ESD) protection diode. Although the main goal of an ESD diode is to protect a system during an ESD event, it has another equally important purpose to fulfill during normal operation: do absolutely nothing.
Customer ServiceSystem-level protection for electrostatic discharge (ESD) is crucial in today''s world, not only in the industrial space but also in the consumer and automotive space. It only takes one ESD strike to permanently damage a product, which makes ESD protection a critical component in a
Customer ServiceIt is important that MLC capacitors, employed as bypass components, absorb the ESD voltage and current safely and protect the device under test with no degradation. In addition, the MLC capacitor must remain within its parametric tolerance for it to be considered a reliable protection mechanism.
Customer ServiceESD (Electrostatic Disharge) is the rapid transfer of electrostatic charge. When one object is positive and another negative and they come into contact, they are going to want to balance their electrons. The rush of electrons from one object to the other is ESD. ESD can be considered an enemy to electronic circuits and their components. The transfer of charge to
