A ceramic resonator is an electronic component that can produce oscillation at a specific frequency when combined with other appropriate components. It consists of a voltage variable capacitor that acts in some ways like a quartz crystal. NewElectronX Ceramic resonators are made of high-stability piezoelectric ceramics, lead zirconium titanate (PZT) which functions as a mechanical resonator. When voltage is applied, ceramic resonator piezoelectric "vibration behavior" causes an oscillating signal. The thickness of the ceramic substrate determines the resonance frequency of our ceramic resonator device. Please select from our frequencies below.
The 4.00 MHz ceramic resonator offers wide frequency range and extended temperature range capabilities.
This 4.75 MHz Ceramic Resonator / crystal are a direct replacement for the hard to find or obsolete 4.75MHz Jerrold audio frequency crystal or equivalent part numbers. The resonant frequency is used in many Jerrold cable box to shift the audio sound (or sound privacy) 250 kc.
Additional applications include: RF modulator of VCR, video disk player, CATV, remote keyless entry, garage openers, and more.
