9B-50.000MBBK-B

Crystals Overview

The 9B-50.000MBBK-B is a parallel third overtone quartz crystal manufactured by TXC Corporation. It operates at a fundamental frequency of 50 MHz with a load capacitance of 20 pF and a frequency stability of ±50 ppm at 25°C. The component utilizes a through-hole mounting configuration, specifically the HC49 package style. Key electrical characteristics include an aging rate of 5 ppm per year and a drive level of 1 µW. It is designed for applications requiring reliable frequency control in standard industrial temperature ranges.

Crystals Feature Summary

• Parallel resonance mode operation utilizing third overtone technology
• Through-hole mounting design compatible with HC49 form factor
• Low drive level specification of 1 µW for stable oscillation
• Aging rate limited to 5 ppm per year for long-term frequency consistency

Crystals Applications

• Industrial control systems requiring precise timing references
• Communication equipment baseband processing circuits
• Test and measurement instrumentation frequency standards
• Consumer electronics clock generation modules

Crystals Procurement Notes

Verify that the target circuit supports parallel resonance configurations and matches the specified 20 pF load capacitance. Confirm mechanical compatibility with the through-hole HC49 footprint during PCB layout. Ensure the operating environment remains within the standard commercial temperature range as no extended grade data is documented. Cross-reference the 1 µW drive level against the oscillator circuit design to prevent overdriving the crystal element.

Crystals Selection Notes

Select this component when a through-hole solution is required for 50 MHz applications. The third overtone design offers advantages in size and phase noise compared to fundamental mode crystals at this frequency. Consider the ±50 ppm stability requirement against system jitter budgets. Evaluate the 5 ppm/year aging rate against the total expected lifecycle drift tolerance. Compare against surface-mount alternatives if board space constraints exist.

Crystals Part Context

This part belongs to the general category of parallel resonant quartz crystals from TXC Corporation. It represents a standard industry form factor (HC49) adapted for surface or through-hole integration depending on specific variant packaging. The 50 MHz frequency is a common reference point for digital logic and microcontroller clocks. Third overtone operation allows for smaller physical dimensions while maintaining high Q-factors necessary for stable oscillation at higher frequencies.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify exact pinout and mechanical dimensions before considering generic equivalents. Ensure any replacement maintains the 20 pF load capacitance and parallel resonance characteristic.
