X10CB1-20.000MHZ-T

Crystals Overview

The MMD X10CB1-20.000MHZ-T is a miniature surface-mount ceramic crystal operating at a nominal frequency of 20.000 MHz. It features a 4-pad SMD package with dimensions of 2.5 mm x 2.0 mm x 0.55 mm. The component has a load capacitance of 10 pF and an equivalent series resistance (ESR) of 80 ohms maximum. Frequency tolerance is specified at ±15 ppm at 25°C, with stability ranging from -30 ppm to +70 ppm over the operating temperature range of -20°C to +70°C. The device supports a maximum drive level of 100 μW.

Crystals Feature Summary

• Ultra-miniature 4-pad ceramic SMD package for space-constrained layouts
• Fundamental mode AT-cut quartz construction for stable oscillation
• Low equivalent series resistance suitable for high-frequency applications

Crystals Applications

• Microcontroller clock sources in compact IoT sensors
• Clock generation for Bluetooth Low Energy modules
• Timing references for wearable devices and smart bands

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance and stability specifications. Confirm that the package orientation and pad layout match the target PCB footprint design. Check RoHS compliance status as indicated in official documentation prior to finalizing procurement orders.

Crystals Selection Notes

Select this component when board real estate is limited and a fundamental mode crystal is required. Ensure the host circuit can support the 10 pF load capacitance without additional external capacitors. Verify that the application environment stays within the -20°C to +70°C operating range to maintain specified frequency stability.

Crystals Part Context

This part belongs to the X10CB1 series of ultra-miniature crystals from MMD Components. The series is designed for applications requiring small form factors while maintaining standard electrical performance characteristics. It serves as a direct replacement for larger 3225 or similar footprint crystals where size reduction is critical.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 2.5x2.0mm 4-pad packages and 10pF load capacitance. Verify ESR limits and drive level requirements before swapping with generic equivalents.
