049ST2-4.897F06DTNJK

Crystals Overview

The 049ST2-4.897F06DTNJK is a quartz crystal resonator manufactured by Suzhou Hangjing Elec&Tech Co., Ltd. It operates at a fundamental frequency of 4.897 MHz with a load capacitance of 6 pF and a maximum equivalent series resistance (ESR) of 100 Ohms. The unit provides a frequency tolerance of ±10 ppm and utilizes an HC-49/US package style for through-hole mounting.

Crystals Feature Summary

• Provides stable frequency generation using quartz crystal technology
• Designed for through-hole integration via standard leaded package
• Supports precise timing requirements with specified load capacitance

Crystals Applications

• Microcontroller clock circuits
• Communication module timing references
• General-purpose oscillator designs

Crystals Procurement Notes

Verify the specific manufacturing date code and lot traceability upon receipt to ensure compliance with project quality standards. Confirm that the physical dimensions match the HC-49/US footprint requirements of the target PCB layout. Inspect terminals for oxidation or damage prior to assembly to guarantee reliable soldering integrity during production.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for low-cost timing applications. Ensure the circuit design accommodates the 100 Ohm ESR limit to prevent excessive power dissipation. Verify that the system load capacitance matches the 6 pF specification to maintain accurate frequency output without requiring external trimming adjustments.

Crystals Part Context

This part belongs to the HC-49/US series of through-hole quartz crystals produced by Suzhou Hangjing Elec&Tech Co., Ltd. Founded in 2014, the company specializes in quartz frequency control components. This specific model represents a standard frequency option within their general-purpose resonator lineup intended for industrial and consumer electronics.

Crystals Replacement Considerations

Direct substitutes must match the 4.897 MHz frequency, 6 pF load capacitance, and HC-49/US package. Verify ESR limits do not exceed 100 Ohms. Check if alternative manufacturers offer compatible pin-out configurations and similar frequency stability ratings.
