049ST2-4.000F16DTJJK

Crystals Overview

The 049ST2-4.000F16DTJJK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 4.000 MHz with a load capacitance of 16 pF. The device exhibits a frequency tolerance of ±30 ppm and an equivalent series resistance (ESR) of 200 Ohms maximum. It utilizes the HC-49S package style, which supports a two-dip lead configuration. This component is designed for precise frequency control applications requiring stable oscillation within specified electrical parameters.

Crystals Feature Summary

• Provides stable frequency control using quartz resonance technology
• Utilizes HC-49S package for reliable mechanical mounting
• Designed for fundamental mode operation at 4 MHz

Crystals Applications

• Consumer electronics timing circuits
• Automotive electronic systems
• Industrial control equipment

Crystals Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct load capacitance and tolerance specifications. Confirm that the HC-49S package dimensions match your PCB layout requirements. Cross-reference the ESR value of 200 Ohms with your oscillator circuit design to guarantee proper startup conditions. Ensure the ±30 ppm stability meets your system's timing accuracy needs before finalizing procurement.

Crystals Selection Notes

Select this component when a 4 MHz fundamental frequency is required with moderate stability. The 16 pF load capacitance must match the external capacitors in the oscillator circuit. Consider the 200 Ohm ESR limit for driving capability requirements. The HC-49S package offers standard mounting compatibility for through-hole assembly processes in general-purpose electronic designs.
