H-Type ceramic resonator

摘要

An H-type ceramic resonator having two resonating leaves, a connecting leaf for bridging the two resonating leaves to form an H-shape, and electrodes disposed on at least both surfaces of the resonating leaves. The resonator has a dimensional relationship which falls within the following equities: B2/B3=4 to 6, B1/B3=2 to 4, and L/B1=5 to 6 wherein L is a length of each of the resonating leaves, B1 is a width of each of the resonating leaves, B2 is a distance between the two resonating leaves, and B3 is a width of the connecting leaf.
