The RSM200S-32.768 is a miniature crystal resonator, specifically a 32.768 kHz crystal, frequently used in real-time clock (RTC) applications. These crystals are essential for maintaining accurate timekeeping in electronic devices. The 'RSM200S' likely indicates the package size and type.

Applications

• Real-time clocks (RTCs) in computers and embedded systems.
• Timekeeping in consumer electronics (watches, clocks, etc.).
• Frequency references for microcontrollers.
• Calibration of other timing circuits.

Features

• 32.768 kHz oscillation frequency.
• Small form factor for space-saving designs.
• High frequency stability.
• Low power consumption.

Benefits

• Accurate timekeeping.
• Long battery life in RTC applications.
• Easy integration into circuit designs.

Additional Details

The 32.768 kHz frequency is chosen because it is easily divided down to 1 Hz for seconds counting. The 'RSM200S' indicates a surface mount package. The crystal is typically housed in a hermetically sealed ceramic package to protect it from environmental factors. The load capacitance is a critical parameter for ensuring accurate frequency, and must be matched to the oscillator circuit's requirements. A datasheet will specify the load capacitance and other important characteristics.
