The K5A11059220204P with SMD5032-4P Crystals ROHS manufactured by KYX is a type of Quartz Crystal Module commonly used in various electronic circuits. It has a 4-pin package, which consists of a SMD5032-4P (Surface Mount Device size 5032-4P) and a resonance system composed of an internal dielectric and metalized electrodes. The module has RoHS (restriction of hazardous substances) compliance and a frequency range of 20.20MHz ± 50ppm. It is a temperature compensated oscillator (TCXO) that is designed to provide high accuracy and low acceleration over temperature. The package size is low profile and small, which makes it an easy to use solution for applications such as clock generators, PLLs, and transmitters.
