0121M4-48.000F09DTNLK

Overview

The 0121M4-48.000F09DTNLK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 48 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 9 pF and an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing control.

Feature Summary

• Provides stable oscillation at 48 MHz with tight frequency tolerance
• Designed for surface-mount integration via 4-SMD no lead package
• Optimized for low impedance operation with 60 Ohm ESR

Applications

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

Procurement Notes

Verify the complete part number including suffixes to ensure correct load capacitance and tolerance specifications. Confirm package dimensions against PCB footprint requirements. Check manufacturer documentation for operating temperature range and storage conditions prior to assembly.

Selection Notes

Select this component when a 48 MHz reference is required with 9 pF load capacitance compatibility. Ensure circuit design accounts for the 60 Ohm ESR value. Validate that the 4-SMD form factor fits within available board space constraints.

Part Context

This crystal belongs to the standard quartz resonator family produced by Suzhou Hangjing. It serves as a passive frequency-determining element in electronic circuits. The 0121M4 series indicates specific physical dimensions and mounting style suitable for automated surface-mount technology processes.

Replacement Considerations

Substitute only with components matching 48 MHz frequency, 9 pF load capacitance, 60 Ohm ESR, and identical 4-SMD package dimensions. Verify pinout compatibility and electrical characteristics before implementation.
