0122M4-12.000F12DTLJK

Overview

The 0122M4-12.000F12DTLJK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 12 MHz with a load capacitance of 12 pF and a maximum equivalent series resistance of 125 Ohms. The component utilizes a 4-SMD, No Lead package configuration suitable for surface-mount assembly. Frequency tolerance specifications are not explicitly confirmed in the provided source data for this specific suffix variant.

Feature Summary

• Surface-mount design utilizing a leadless four-terminal SMD package structure
• Quartz-based resonant element providing stable frequency control
• Engineered for integration into electronic circuits requiring precise timing signals

Applications

• General purpose clock signal generation in consumer electronics
• Timing reference sources for microcontroller systems
• Frequency control units in communication devices

Procurement Notes

Verify the exact frequency tolerance specification against the manufacturer's official datasheet prior to procurement, as public distributor listings may vary regarding tolerance values for specific suffixes. Confirm that the 4-SMD no-lead package dimensions align with the target PCB footprint requirements. Ensure compatibility with standard reflow soldering profiles applicable to quartz crystal components.

Selection Notes

Select this component when a 12 MHz surface-mount crystal with a 12 pF load capacitance is required. Evaluate the 125 Ohm maximum ESR limit against the oscillator circuit's drive level constraints. Consider the leadless SMD form factor for automated assembly processes where space efficiency and thermal performance are prioritized over through-hole mounting options.

Part Context

This part belongs to the quartz crystal resonator family produced by Suzhou Hangjing Elec&Tech Co., Ltd., a company specializing in frequency control units. The model number indicates specific electrical parameters including frequency, load capacitance, and package type. Similar variants exist within the product line offering different frequencies or tolerance levels while maintaining comparable physical footprints.

Replacement Considerations

Direct substitutes include the 0122M4-12.000F12DTNJK, which shares identical electrical parameters but may differ in tolerance specifications. Verify pinout compatibility and mechanical dimensions before substitution. Alternative crystals from other manufacturers must match the 12 MHz frequency, 12 pF load capacitance, and 4-SMD no-lead package geometry.
