0121M4-38.400F04DWNL-LAGK

Overview

The 0121M4-38.400F04DWNL-LAGK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec & Tech Co., Ltd. It operates at a fundamental frequency of 38.4 MHz with a specified load capacitance of 4 pF and an equivalent series resistance (ESR) of 80 Ohms. The unit features a frequency tolerance of ±10 ppm and is housed in a compact 4-SMD, No Lead package suitable for surface-mount assembly.

Feature Summary

• Provides stable frequency generation at 38.4 MHz using quartz resonance technology
• Designed for surface-mount integration via a leadless SMD package configuration
• Maintains frequency stability within ±10 ppm tolerance under specified load conditions

Applications

• Automotive electronics systems requiring precise timing references
• Consumer electronic devices utilizing standard clock frequencies
• Network communication equipment needing stable oscillator sources

Procurement Notes

Verify the component authenticity against official Suzhou Hangjing documentation. Confirm that the 4-SMD no-lead package matches your PCB footprint requirements. Ensure the 38.4 MHz frequency and 4 pF load capacitance align with your circuit design specifications before finalizing orders.

Selection Notes

Select this component when a 38.4 MHz reference is required for surface-mount designs. The 80 Ohm ESR and 4 pF load capacitance must match the oscillator circuit parameters. Consider the ±10 ppm tolerance for applications where moderate frequency accuracy is sufficient.
