AVX – new ESD-Safe Multilayer Ceramic Chip Capacitors
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 charge and integrate it down to a lower level that the IC can handle. Capacitance selection is a trade off. Large capacitance values provide better ESD protection, however a larger capacitance could corrupt the data stream.
ESD-Safe™ X7R 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 coefficient. The product is available in a wide capacitance range from 4.7nF up to 2.2µF.
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.
