MP500B-E

Crystals Overview

The MP500B-E is a 50 MHz fundamental mode crystal resonator manufactured by CTS-Frequency Controls. It operates within a temperature range of -40°C to +85°C and features an HC-49/U package. Key electrical parameters include a frequency stability of ±50ppm, a frequency tolerance of ±30ppm, a load capacitance of 18pF, and an equivalent series resistance (ESR) of 55 Ohms. The component supports through-hole mounting and complies with RoHS3 standards.

Crystals Feature Summary

• Fundamental mode operation at 50 MHz for precise timing applications
• Wide operating temperature range from -40°C to +85°C
• Robust shock performance suitable for demanding environments

Crystals Applications

• Microprocessor systems
• Telecommunication equipment
• Industrial electronics
• Consumer electronics
• Networking applications

Crystals Procurement Notes

Verify the specific suffix 'E' corresponds to the required RoHS3 compliance and lead-free status when sourcing. Confirm that the HC-49/U package dimensions match the PCB footprint requirements. Ensure the 55 Ohm ESR and 18pF load capacitance align with the oscillator circuit design specifications to guarantee stable frequency generation.

Crystals Selection Notes

Select this component when a 50 MHz fundamental resonance is required with ±30ppm initial tolerance. The HC-49/U package offers standard through-hole compatibility. Consider the ±50ppm stability over temperature if the application environment varies significantly between -40°C and +85°C. Verify that the 55 Ohm ESR is compatible with the driving circuit's power constraints.

Crystals Part Context

This part belongs to the CTS Frequency Controls crystal resonator family, designed for general-purpose timing needs. The MP500B-E variant specifically addresses applications requiring high shock resistance and wide temperature stability. It serves as a core timing element in digital circuits where accurate clock signals are critical for data synchronization and processing integrity.

Crystals Replacement Considerations

Direct substitutes must match the 50 MHz frequency, HC-49/U package, and 18pF load capacitance. Verify equivalent ESR values around 55 Ohms and similar stability ratings. Cross-reference manufacturer-specific pinouts and mechanical tolerances to ensure physical compatibility without redesigning the host PCB layout.
