Ceramic can work chemically as a catalyzer, a filter or as a sensor, through its surface-active properties. Ceramic also solves thermal problems like no other material. It can isolate or conduct, insulate or store. But ceramic can do a lot more - it can alter the flow of electric current. Such electro-ceramics have many uses: as electrical conductors, semiconductors, semiconductors and isolators, for filtering and storing, and to convert electrical energy into mechanical energy.
Epcos is the company that manufactures all the various ceramic products at one site. These include microwave ceramics (RF filters), thermistors (temperature dependent resistors like NTCs and PTCs), multilayer ceramic capacitors (extremely high capcitance within the smallest confines) varistors (voltage dependent resistors), piezo components (mechanical motion through electrical stimulation) and LTCC modules (low temperature co-fired ceramics).
