SC-20S SMD Quartz Crystal Units

Seiko Instruments SC-20S SMD Quartz Crystal Units include a built-in crystal resonator processed by highly reliable photolithographic technology. These crystal units are thin type with 0.6mm height and are suitable for high-density surface mounting. The SC-20S units feature excellent shock and heat resistance, 32.768kHz nominal frequency, ±20 x 10-6 frequency tolerance, 6pF to 12.5pF load capacitance, and 70kΩ maximum motional resistance (ESR). These crystal units are lead-free and comply with the EU RoHS directive. The SC-20S crystal units are used in mobile phones, wearables, modules, and sub-clock functions for various microcomputers.
