MC-146 32.768K-AA

The MC-146 32.768K-AA quartz crystal is a standard timing element for real-time clock modules and low-power timing applications. With a nominal frequency of 32.768kHz and a specified load capacitance (commonly 12.5pF), this crystal supports long-term accuracy and low power consumption—criteria important to battery-operated devices and embedded RTC functions. Its industry-standard frequency allows easy division to one-second time bases, which is why it remains ubiquitous in clock and timing designs. Sourcing from a reputable manufacturer such as Epson ensures consistent frequency stability and predictable start-up characteristics. Florida Circuit offers genuine crystals alongside advice on matching load capacitors and PCB layout practices to minimize drift and optimize oscillation. Use MC-146 crystals for compact, low-power timekeeping solutions across consumer and industrial designs.
