0111M4-27.120F12DWNJK

Overview

The 0111M4-27.120F12DWNJK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 27.12 MHz with a specified load capacitance of 12 pF and an equivalent series resistance (ESR) of 125 Ohms. The component exhibits a frequency tolerance of ±10 ppm. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount integration into electronic circuits requiring stable frequency control.

Feature Summary

• Provides precise frequency generation using quartz resonator technology
• Designed for direct surface-mount assembly on printed circuit boards
• Engineered to maintain stability under defined load capacitance conditions

Applications

• Frequency reference circuits in consumer electronics
• Clock signal generation in communication modules
• Timing sources in embedded microcontroller systems

Procurement Notes

Verify the manufacturer designation as Suzhou Hangjing Elec&Tech Co., Ltd. Confirm the specific load capacitance of 12 pF and ESR of 125 Ohms match system requirements. Ensure the 4-SMD No Lead package type is compatible with the intended PCB footprint and reflow soldering profile. Cross-reference the full part number to distinguish from similar variants with different tolerances or frequencies.

Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±10 ppm accuracy. The 12 pF load capacitance must align with the oscillator circuit design. The low ESR of 125 Ohms supports efficient energy transfer. The SMD form factor is suitable for automated assembly processes in high-volume manufacturing environments.

Part Context

This crystal belongs to the 0111M4 series of quartz frequency control units produced by Suzhou Hangjing. The company specializes in research, development, and production of quartz components. This specific model represents a standard surface-mount solution for applications needing reliable timing signals without the need for additional packaging or lead frames.

Replacement Considerations

Direct substitutes must match the 27.12 MHz frequency, 12 pF load capacitance, 125 Ohm ESR, and 4-SMD No Lead package. Verify that alternative manufacturers offer identical electrical parameters and mechanical dimensions to ensure pin-to-pin compatibility and performance equivalence.
