0111M4-40.000F10DTNJK

Overview

The 0111M4-40.000F10DTNJK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 40.000 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 80 Ohms. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Provides stable oscillation at 40 MHz with high frequency accuracy
• Utilizes a lead-free surface-mount package for automated assembly
• Engineered for low power consumption and reliable performance

Applications

• Microcontroller clock sources
• Communication module timing circuits
• Digital signal processing systems

Procurement Notes

Verify the manufacturer part number against official Suzhou Hangjing documentation to ensure authenticity. Confirm that the specific suffix matches the required load capacitance and tolerance specifications for your circuit design. Request material certificates if compliance with environmental standards is mandatory for your production line.

Selection Notes

Select this component when a 40 MHz reference is required with ±10 ppm stability. Ensure the circuit load capacitance matches the specified 10 pF to maintain accurate frequency. Verify that the PCB footprint accommodates the 4-SMD no-lead package dimensions and that the operating temperature range meets system requirements.

Part Context

This crystal belongs to the standard SMD quartz resonator family produced by Suzhou Hangjing. It serves as a passive frequency control element, distinct from active oscillators. The model designation indicates specific electrical parameters including frequency, tolerance, and package type within the company's product lineup.

Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 10 pF load capacitance, 80 Ohm ESR, and 4-SMD no-lead package. Verify pin compatibility and thermal characteristics before swapping. Generic crystals may not meet the specific ±10 ppm tolerance or package constraints.
