049ST2-3.579545F18DTNJK

Crystals Overview

The 049ST2-3.579545F18DTNJK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 3.579545 MHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 200 Ohms. It utilizes the HC-49S package, which is a standard through-hole mounting configuration. The physical dimensions are specified as 11.05 mm in length, 4.65 mm in width, and 3.5 mm in height.

Crystals Feature Summary

• Provides stable frequency control using quartz resonance technology
• Designed for through-hole mounting applications via HC-49S package
• Offers precise frequency stability within specified tolerance limits

Crystals Applications

• Clock signal generation in digital circuits
• Microcontroller oscillator inputs

Crystals Procurement Notes

Verify the specific suffix 'F18' corresponds to the required 18 pF load capacitance for your circuit design. Confirm that the 200 Ohm ESR value aligns with the oscillator circuit requirements. Ensure the HC-49S package size fits the PCB footprint constraints. Check for any specific moisture sensitivity or storage conditions if applicable to your assembly process.

Crystals Selection Notes

Select this component when a 3.579545 MHz reference is needed with ±10 ppm accuracy. The 18 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the HC-49S package for reliable through-hole assembly. Evaluate the 200 Ohm ESR against the driver strength of the target microcontroller or oscillator IC.

Crystals Part Context

This part belongs to the quartz crystal resonator category produced by Suzhou Hangjing Elec&Tech Co., Ltd., established in 2014. The company specializes in research, development, and production of quartz frequency controlling units. This specific model is part of their standard crystal lineup designed for general electronic applications requiring precise timing.

Crystals Replacement Considerations

The model 049ST2-3.579545F20DTNJK is a similar variant from the same manufacturer but features a 20 pF load capacitance instead of 18 pF. Substitution requires verification that the circuit can accommodate the different load capacitance without affecting frequency accuracy.
