YSX321SL 27.12 MHz 10pF ±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 housed in a protective metal package. Operating at 27.12 MHz, this crystal is engineered specifically for RF applications, including NFC (Near-Field Communication) and HF RFID systems, where frequency precision is paramount for successful contactless data transmission.

Featuring a 4-pin SMD configuration and a rugged metal surface finish, the YSX321SL offers superior electromagnetic shielding, which is critical for reducing interference in densely packed RF communication circuits. With a low load capacitance of 10 pF and a tight frequency tolerance of ±10 ppm, this crystal provides a clean, stable clock reference to ensure maximum data integrity and reliable read ranges. This pack includes two units, making it an excellent choice for dual-antenna designs or high-reliability hardware prototyping.
