By Dr. KH MunSmaller TCXO packages are used and sometimes required for many different applications, but there have been drawbacks to their small size. While the crystal blank can be produced in a small enough size, incorporating ICs inside the package meant sacrificing their aging performance and stability [2]. To solve this issue, Suntsu is…

By Dr. KH MunSuntsu’s new RTC (Real-Time Clock), SLR32CN-32.768K, has a built-in 32.768kHz TCXO with an I2C bus interface and provides ultra-low power consumption. The 32.768 kHz crystal is the long-standing RTC timekeeping standard — 2¹⁵ Hz divides cleanly to a one-second tick — and pairing it with an I²C interface and microamp-level current draw…

By Dr. KH Mun Watch Crystal Shortages? The world’s most popular tuning fork watch crystal has been the 3.2mm x 1.5mm package for a long time. Suntsu’s equivalent watch crystal, the SWS312 series, has been popular among our customers! Unfortunately, this part is becoming harder and harder to find in the marketplace, and lead times…

By Dr. KH MunSuntsu now offers foot switches! Foot switches are used to turn electrical equipment on and off by using your foot to trigger the switch, depending on the application. Some common applications of foot switches include guitar pedals, sewing machines, medical bed controls, tattoo guns, soldering machines, industrial machinery, and more. The right…

By Dr. KH MunBattery-powered, wireless communication products require not only a high data rate but low current consumption to reduce power loss. Suntsu is introducing a new set of crystal oscillators, the SLO series, to meet these market demands! With the lowest current consumption and unmatchable phase noise performance, the SLO series is the only…
