X10CB1-26.000MHZ-T

Crystals Overview

The MMD X10CB1-26.000MHZ-T is a miniature surface-mount ceramic crystal oscillator operating at a fundamental frequency of 26.000 MHz. It features a load capacitance of 10 pF and an equivalent series resistance (ESR) maximum of 80 ohms within the 20.000–29.999 MHz range. The component exhibits a frequency tolerance of ±15 ppm at 25°C and stability of ±30 ppm across the -20°C to +70°C operating temperature range. It utilizes a 4-pad SMD package measuring 2.5 mm x 2.0 mm x 0.55 mm with a maximum drive level of 100 µW.

Crystals Feature Summary

• Ultra-miniature four-pad surface-mount ceramic package design for space-constrained applications
• Fundamental AT-cut mode operation ensuring stable frequency generation
• RoHS compliant construction suitable for environmentally regulated manufacturing processes

Crystals Applications

• Clock signal generation for microcontrollers and digital logic circuits
• Timing reference sources for communication interface modules
• Frequency control in portable consumer electronic devices

Crystals Procurement Notes

Verify the specific frequency suffix matches the required system clock speed, as the X10CB1 series offers multiple standard frequencies. Confirm that the 80 ohm ESR limit aligns with the oscillator circuit design requirements. Ensure the 10 pF load capacitance is compatible with the host device's internal capacitance settings. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Validate the 4-pad soldering footprint against the target PCB layout specifications.

Crystals Selection Notes

Select this component when a small form factor is critical for the design. The 26 MHz frequency suits applications requiring moderate-speed timing references. Consider the 80 ohm ESR value to ensure proper oscillation startup conditions are met by the driving circuit. The wide commercial temperature range supports general-purpose electronics rather than harsh industrial environments. Verify that the 100 µW drive level prevents overdriving the crystal element.

Crystals Part Context

This part belongs to the X Series of ultra-miniature crystals from MMD. The series is characterized by its compact 2.5 mm x 2.0 mm ceramic package. These components are designed for high-volume surface-mount assembly processes. The product line provides various frequency options within the 16 MHz to 60 MHz range.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' 26 MHz crystals in identical 2.5x2.0mm 4-pad packages. Verify that any replacement maintains the same 10 pF load capacitance and 80 ohm maximum ESR. Ensure the replacement part meets the same ±15 ppm tolerance and ±30 ppm stability specifications.
