Epcos has extended its ESD protection component offering with low-capacitance CeraDiodes and multilayer varistors (MLV) in a 0201 package. The variants with capacitances of 22 pF are distinguished by a low clamping voltage and are suited for the protection of LED background lighting, for example. Types with capacitances of up to 10 pF have also been developed for USB and Ethernet systems. Because of the need to minimise parasitic capacitances, especially in RF technology, the company is also developing a special antenna varistor with a capacitance of less than 1 pF.
Epcos has developed two types of ESD/EMI filter arrays. The 0405 audio filter protects microphone and loudspeaker leads from ESD damage and interference, and RC filters in 0508 and 0306 packages were developed to protect display lines. While the audio filter replaces 10 discrete components, the RC filter takes the place of 20 components packed in a single package. This level of integration allows the number of individual components on the circuit board to be reduced, thus increasing the reliability of the equipment, as fewer solder points are needed. In addition, development costs are also reduced.
