YSX321SL 27.12 MHz 20pF ±10ppm 4-Pin SMD Metal Surface Quartz Crystal (Pack of 2)

Description

The YSX321SL 27.12 MHz is a high-precision, 4-pin surface-mount quartz crystal engineered to provide a stable frequency reference. Operating at 27.12 MHz, this frequency is an internationally recognized ISM band (Industrial, Scientific, and Medical) frequency. It is widely used in short-range wireless communication applications, including RFID systems, near-field communication (NFC), and various low-power wireless modules.

Encased in a robust metal-surface SMD package, the YSX321SL is designed for high-density PCB layouts and automated surface-mount assembly. With a load capacitance of 20 pF and a tight frequency tolerance of ±10 ppm, this crystal provides the excellent thermal and mechanical stability required for reliable signal modulation and frequency synthesis in wireless hardware. This package includes two units, making it highly convenient for manufacturing or prototyping.
