Quartz Crystals

SII offers precise 32.768kHz tuning-fork quartz crystals in a wide range of small through-hole (tubular, VT), plastic-molded (SSP) and tiny ceramic (SCX) SMD packages down a size of 1.2mm.


SII semiconductors focus on low-voltage applications and are well-known for its high reliability and low current consumption. Standard packages like SOT-23-5 (2.9 x 2.8 x 1.3 mm) as well as very compact packages like HSNT-4 (0.8 x 0.8 x 0.4 mm) are available.
