AVX Corporation has developed a new series of enhanced MLC capacitors specifically designed for general ESD protection. The small footprint makes them ideal for high densityA figure of merit usually expressed in Joules per cubic inch for capacitors electronic devices like automotive modules, which often use ESD caps on nearly every pin.
The ESD-Safe series is an enhanced MLC capacitor developed and designed specifically to be used in applications which are sensitive to ESD (Electro Static Discharge) events.
ESD-Safe capacitors are commonly utilized to protect general-purpose I/O lines from ESD damage. These devices will take the ESD chargeThe amount of electricity present upon the capacitor's plates. Also, the act of forcing of electrons onto the capacitor's plates. See CoulombA coulomb is the unit of electric charge. It is named after Charles-Augustin de Coulomb.1 coulomb is the amount of electric charge transported by a current of 1 ampere in 1 second. It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference.. and integrate it down to a lower level that the IC can handle. CapacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. selection is a trade off. Large capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. values provide better ESD protection, however a larger capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. could corrupt the data stream.
ESD-Safe X7RThe main differences between ceramic dielectricThe insulating material between the plates of the capacitor. The material is chosen for its ability to permit electrostatic attraction and repulsion to take place across it. The material will have the property that energy required to establish an electric field is recoverable in whole or in part, as electric energy. In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. types are the temperature coefficient of capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors.

In other words, a good dielectric material is a poor conductor of electricity while being an effective supporter of electrostatic fields. loss.Ceramic capacitors tend to have low inductance because of their small size. Series capacitors are available in standard 0603, 0805 and 1206 case sizes. The AECQ200-qualified chips are available in 25, 50 and 100V, feature a +/-15% temperature coefficientThe change in capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. with temperature expressed linearly as parts per million per degree centigrade (PPM/°C), or as a percent change over a specified temperature range. Most film capacitors are not linear and TC is expressed in percent.. The product is available in a wide capacitanceThat property of a system of conductors and dielectrics which permits the storage of electricity when potential difference exists between the conductors. Its value is expressed as the ratio of a quantity of electricity to a potential difference. A capacitance value is always positive. range from 4.7nF up to 2.2μFUnit of capacitance. The basic unit of a measure of a capacitor. A capacitor charged to 1 volt with a charge of 1 coulombA coulomb is the unit of electric charge.

It can also be defined in terms of capacitance and voltage, where one coulomb is defined as one farad of capacitance times one volt of electric potential difference. would have a capacitance of 1 farad. 1 microF = .000001 Farads..
Further key features of the ESD-Safe series are the operating temperature range of Class II ceramic -55 to +125°C , ΔC/C0 = ±15 % , an ESD rating of 18kV – 30kV and the availability of FLEXITERM, which allow for more than twice board flexure compared to standard terminations.
