Frequently Asked Questions
What load capacitance and drive level does the ECS-.327-7-12-TR require for correct oscillator operation?
The ECS-.327-7-12-TR requires a 7 pF load capacitance and operates at a drive level of 0.5 µW, which makes it compatible with the oscillator inputs of most modern low-power microcontrollers and RTC ICs designed for 32.768 kHz crystals.
How accurate is the ECS-.327-7-12-TR for real-time clock designs that must stay synchronized over one year?
The crystal provides a frequency tolerance of 20 ppm and an aging specification of 3 ppm per first year, so a timekeeping circuit can expect less than 1 second of drift per day under nominal 25°C conditions, suitable for consumer RTC and IoT applications.
Which low-power embedded platforms benefit from the ECS-.327-7-12-TR's 32.768 kHz frequency?
Microcontroller platforms such as STM32, nRF52, and ESP32 with onboard RTC peripherals benefit from this crystal's 32.768 kHz parallel-fundamental frequency and 7 pF load capacitance, enabling battery-backed timekeeping in IoT nodes, wearables, and smart meters drawing only 0.5 µW from the oscillator circuit.
Is the ECS-.327-7-12-TR available in tape-and-reel format for automated SMT assembly?
Yes, the TR suffix in ECS-.327-7-12-TR designates tape-and-reel packaging, and the 2-pin SMD footprint is compatible with standard pick-and-place equipment, supporting efficient automated reflow assembly for high-volume production runs of RTC boards and IoT sensor modules.
