X10CB1-40.000MHZ-T

Crystals Overview

The MMD X10CB1-40.000MHZ-T is a surface-mount ceramic crystal from the X Series, designed for compact electronic applications. It operates at a fundamental frequency of 40 MHz with a load capacitance of 10 pF. The component features a 4-SMD, no-lead package measuring 2.0mm x 2.5mm. It supports a frequency stability of ±15 ppm over temperature and ±30 ppm initially. The equivalent series resistance (ESR) is specified at a maximum of 50 Ohms, with a drive level limit of 100 μW. The device is RoHS compliant and suitable for industrial temperature ranges.

Crystals Feature Summary

• Fundamental AT-cut resonance technology ensuring stable oscillation characteristics
• Low equivalent series resistance design facilitating reliable startup in low-power circuits

Crystals Applications

• Microcontroller unit clock generation
• Bluetooth module timing reference
• Low-power IoT sensor nodes

Crystals Procurement Notes

Verify that the specific order code matches the required frequency tolerance and load capacitance specifications for the target circuit design. Confirm packaging format requirements, as standard supply typically utilizes tape and reel configurations for automated surface-mount assembly processes. Ensure compatibility with reflow soldering profiles defined by the manufacturer's datasheet to maintain component integrity during production.

Crystals Selection Notes

Select this component when board real estate is limited to a 2x2.5mm footprint. The 10 pF load capacitance requires matching external capacitors in the oscillator circuit. The 50 Ohm ESR specification must be validated against the host oscillator's minimum start-up requirements. This part is intended for applications requiring fundamental mode operation rather than overtone modes.

Crystals Part Context

This model belongs to the MMD X Series, a line of miniature ceramic crystals engineered for high-volume consumer and industrial electronics. The series emphasizes reduced physical dimensions compared to standard 3225 packages while maintaining electrical performance standards. The X10CB1 suffix denotes the specific 4-terminal ceramic construction variant within this product family.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz, 10 pF, 2x2.5mm SMD crystals from competing manufacturers such as ECS or NDK. Verify pinout compatibility and mechanical height restrictions before swapping. Alternative frequencies in the same package require separate part number validation.
