MP-1-R 4.000000 W/GRD WIRE

Overview

The MtronPTI MP-1-R 4.000000 W/GRD WIRE is a fundamental mode quartz crystal resonator operating at a nominal frequency of 4 MHz. It features a frequency tolerance of ±30 ppm and a load capacitance of 18 pF. The device exhibits an equivalent series resistance of 75 Ohms and utilizes the standard HC-49/U package format. This component serves as a precise timing element for electronic circuits requiring stable oscillation frequencies.

Feature Summary

• Provides stable fundamental frequency oscillation
• Utilizes standard HC-49/U metal can packaging
• Designed for general-purpose timing applications

Applications

• Avionics systems
• Navigation systems
• Radar systems
• Communication equipment

Procurement Notes

Verify that the specific suffix 'W/GRD WIRE' matches the required grounding configuration for your circuit design. Confirm the load capacitance requirement of 18 pF aligns with the oscillator circuit specifications to ensure accurate frequency performance. Ensure the HC-49/U package dimensions fit within the designated footprint on the printed circuit board.

Selection Notes

Select this component when a 4 MHz reference signal is required with moderate stability. The ±30 ppm tolerance suits applications not demanding extreme precision. Consider the 75 Ohm ESR for driver capability matching. Verify environmental ratings if operating in harsh conditions, as standard crystals may have limited temperature ranges compared to TCXO variants.

Part Context

This part belongs to the MP-1 series of quartz crystals manufactured by MtronPTI. The series offers various frequency options within the HC-49/U form factor. The 'R' suffix typically indicates a reel or tape-and-reel packaging variant, while 'W/GRD WIRE' specifies the internal lead configuration for grounding purposes.

Replacement Considerations

Compatible substitutes include other manufacturers' HC-49/U crystals with identical 4 MHz frequency, 18 pF load capacitance, and similar ESR values. Ensure any replacement maintains the same physical pinout and grounding wire specification to avoid PCB redesign.
