MHz Crystal Units

MHz crystal units are precision timing devices that provide stable frequency control across a wide range of electronic systems, from high-speed data communication equipment to ultra-compact wearable devices such as hearing aids. As electronic devices continue to shrink, engineers must address two conflicting challenges: minimizing PCB footprint while preventing increased ESR (Equivalent Series Resistance). River Eletec overcomes this challenge with its proprietary Electron Beam Sealing (EBS) technology.
Even in an ultra-miniature 1.2 × 1.0 mm-class package, vacuum sealing enables extremely high Q characteristics, low ESR, and excellent long-term stability. For engineers who meticulously tune their own oscillator circuits to minimize mounting costs and power consumption, these crystal units are the optimal components—delivering reliable, low phase-noise clock performance for advanced hardware designs.
