MX3DHHC26M0

Crystals Overview

The Meritek MX3DHHC26M0 is a surface-mount quartz crystal unit designed for fundamental parallel resonance operation. It operates at a nominal frequency of 26.0 MHz with a load capacitance of 30 pF and a frequency tolerance of ±30 ppm. The component features a seam-sealed ceramic package measuring 5.0 x 3.2 mm, supporting an operating temperature range from -20°C to +70°C. It exhibits a maximum aging rate of 5 ppm per year and a series resistance of 50 ohms.

Crystals Feature Summary

• Seam-sealed ceramic construction provides excellent heat resistance and environmental stability.
• Low profile surface mount design facilitates automated assembly in compact electronic systems.
• Fundamental parallel resonance mode ensures precise timing control for digital circuits.

Crystals Applications

• Mobile communication devices
• Wireless LAN modules
• Test equipment

Crystals Procurement Notes

Verify the specific suffix codes against official Meritek documentation to confirm exact frequency tolerance and temperature range specifications. Ensure that the ordering information matches the required load capacitance and aging rates for the target application. Cross-reference part numbers with authorized distributors to avoid counterfeit components and ensure compliance with RoHS standards.

Crystals Selection Notes

Select this component when a 26 MHz reference signal is required within a -20°C to +70°C operational window. The 30 pF load capacitance must align with the oscillator circuit design to maintain the specified ±30 ppm frequency accuracy. Consider the 50-ohm series resistance and 10 µW drive level limits during schematic design to prevent overdriving the crystal element.

Crystals Part Context

This part belongs to the Meritek MX3 series of ceramic SMD crystals, characterized by a 5.0 x 3.2 mm footprint. The series utilizes seam-sealed technology to enhance reliability compared to standard epoxy-sealed units. It serves as a passive timing component for generating stable clock signals in high-frequency applications requiring moderate stability.

Crystals Replacement Considerations

Direct substitutes include other Meritek MX3 series variants with identical 5.0 x 3.2 mm dimensions and 26 MHz frequency, such as MX3DHHB26M0 or MX3DHHD26M0, provided their tolerance and temperature ranges meet the system requirements. Verify pin compatibility and electrical parameters before substitution.
