Multilayer Ceramic (MLC) Capacitor is a monolithic block of ceramic
containing two sets of offset, interleaved planar electrodes that
extend to two opposite surfaces of the ceramic dielectric. This simple
structure requires a considerable amount of sophistication, both in material
and in manufacture, to produce it in the quality quantities needed in today's
electronic equipments.
Metal oxide varistor (MOV) is a voltage dependent resistor with
symmetrical voltage-current characteristics that is design to protect
all kinds of electronic devices or elements from switching and induced
lighting surges. Its non linear exponent characteristics with broad using
range and mass production is gradually being used by various level of electric
engineering.
