MP-1-R 4.000000

Overview

The MtronPTI MP-1-R 4.000000 is a through-hole MHz crystal housed in an HC-49/U package. It operates at a nominal frequency of 4 MHz with a frequency tolerance of ±30 ppm and stability of ±50 ppm. The component supports a load capacitance of 18 pF and exhibits an impedance of 75 Ohms. It functions within an operating temperature range of -10°C to +70°C.

Feature Summary

• HC-49/U through-hole mounting configuration
• HCMOS/TTL compatible operation
• RoHS compliant construction

Applications

• General purpose clock generation
• Microcontroller timing circuits
• Digital logic synchronization

Procurement Notes

Verify the specific suffix requirements for your application, as the base model may vary by lead wire configuration or packaging type. Confirm that the HC-49/U form factor aligns with your PCB footprint constraints. Ensure the ±30 ppm tolerance meets your system's timing accuracy needs before finalizing the order.

Selection Notes

Select this component when a standard through-hole crystal is required for 4 MHz applications. The HC-49/U package offers robust mechanical stability for general electronics. Consider the ±30 ppm tolerance against your system's jitter budget. Verify compatibility with HCMOS or TTL logic families driving the crystal circuit.

Part Context

This part belongs to MtronPTI’s standard MHz crystal lineup. It utilizes the widely adopted HC-49/U case style, ensuring broad availability and ease of integration into legacy and modern designs. The product is actively manufactured and supported by the vendor.

Replacement Considerations

Direct substitutes include other manufacturers' HC-49/U crystals rated at 4 MHz with ±30 ppm tolerance and 18 pF load capacitance. Ensure equivalent impedance and drive level specifications are matched to maintain circuit performance.
