0121M4-16.000F09DTNLK

Overview

The 0121M4-16.000F09DTNLK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co.,Ltd. It operates at a fundamental frequency of 16 MHz with a load capacitance of 9 pF and an equivalent series resistance of 100 Ohms. The component utilizes a 4-SMD, No Lead package configuration designed for surface-mount assembly. This specific part number variant indicates the presence of the 'L' suffix, which typically denotes lead-free construction compliant with environmental standards, distinguishing it from standard tin-lead variants within the same electrical specification family.

Feature Summary

• Fundamental mode quartz crystal operation providing stable frequency generation
• Surface-mount compatible 4-SMD no-lead package design for automated assembly
• Lead-free construction suitable for RoHS-compliant manufacturing processes

Applications

• Microcontroller clock source circuits
• Communication module timing references
• Digital signal processing system oscillators

Procurement Notes

Verify the exact suffix designation against the manufacturer's current datasheet to confirm lead-free status and tolerance specifications. Ensure the load capacitance matches the oscillator circuit requirements. Confirm package dimensions align with PCB footprint constraints before finalizing procurement orders.

Selection Notes

Select this component when a 16 MHz fundamental frequency is required with a 9 pF load capacitance. Consider the 4-SMD no-lead package for space-constrained designs requiring reflow soldering compatibility. Evaluate the 100 Ohm ESR against the oscillator circuit's drive level limitations to ensure reliable startup and long-term stability.

Part Context

This part belongs to the M4 series of quartz crystal resonators produced by Suzhou Hangjing. The series offers various frequencies and package options. The 0121M4 prefix identifies the specific form factor and electrical characteristics common to this product line segment.

Replacement Considerations

Direct substitutes must match the 16 MHz frequency, 9 pF load capacitance, and 4-SMD no-lead package. Verify ESR values and operating temperature ranges. Cross-reference with other manufacturers offering identical pinout and electrical parameters.
