Features of TC20A026000GECN11G

1. Ultra-High Frequency Stability (±0.5 ppm vs. Temperature)

Built-in temperature compensation circuit minimizes frequency drift caused by temperature changes, far superior to standard crystal oscillators (VCXO/OCXO), achieving high-precision frequency reference without external compensation.


2. High Frequency Tolerance (±1.5 ppm)

Exceptional initial accuracy, meeting the stringent frequency requirements of 5G communication, GNSS navigation, and other critical systems.


3. Ultra-Wide Industrial Temperature Range (-40~85℃)

Covers the full industrial temperature range, suitable for harsh environments such as automotive electronics and industrial control.


4. Ultra-Low Power Consumption (2.0 mA)

Extremely low power for a TCXO, ideal for battery-powered portable devices and IoT terminals to extend battery life.


5. Miniature 2016 Package (2.0×1.6mm)

Ultra-compact form factor, suitable for space-constrained PCB layouts, supporting JEDEC standard reflow soldering.


6. Low Annual Aging (±1.0 ppm/year)

Outstanding long-term frequency stability, reducing the need for periodic calibration and lowering system maintenance costs.


7. Industry Applications

With its 26 MHz high-frequency output, ±0.5 ppm ultra-high temperature stability, ±1.5 ppm high tolerance, -40~85℃ industrial wide temperature range, 2.0 mA ultra-low power consumption, and 2016 miniature package, the TC20A026000GECN11G is widely used in 5G communication base stations, GPS/Beidou high-precision navigation, automotive electronics, industrial IoT terminals, test & measurement equipment, aerospace & defense, and medical devices that demand stringent high-frequency accuracy and temperature compensation.
