JWT Crystal's 32.768kHz Tuning Fork Crystals are passive resonators for real-time clock (RTC) and timing circuits. The current range includes 1.6 x 1.0 mm, 2.0 x 1.2 mm, 3.2 x 1.5 mm, and 7.0 x 1.5 mm SMD packages plus JU308/JU206 cylindrical packages. Existing Datasheets specify customized load capacitance for DJ1610, DI2012, TF3215, and DFC3215; 7 pF, 9 pF, or 12.5 pF for SMD7015; and 6 pF, 7 pF, 9 pF, or 12.5 pF for JU308/JU206. Maximum ESR values range from 50/60 kΩ for JU308/JU206 to 90 kΩ for DJ1610. Select by package, load capacitance, ESR, operating temperature, and the requirements of the external oscillator or RTC IC.
Microwatt drive-level ratings support battery-operated RTC circuits; total current is determined by the external oscillator.
Exact 32.768kHz frequency generating standard 1-second real-time clock signals.
Available in ultra-miniature SMD (3215, 2012, 1610) and cylindrical DIP (MC-146, 3x8, 2x6).
Low ESR design ensuring fast oscillator start-up under low voltage conditions.
