STDCTX1-19.2M

Overview

The STDCTX1-19.2M is a surface-mount crystal oscillator manufactured by NDK (Nihon Dempa Kogyo Co., Ltd.). It operates at a fundamental frequency of 19.2 MHz with a load capacitance of 7 pF and an equivalent series resistance of 70 Ohms. The component features a ±10 ppm frequency tolerance and utilizes a 4-SMD, no-lead package for compact integration.

Feature Summary

• Provides stable oscillation at 19.2 MHz with high frequency accuracy
• Designed for surface-mount assembly to support automated manufacturing
• Optimized low power consumption characteristics suitable for portable devices

Applications

• Mobile communication modules requiring precise clock synchronization
• Consumer electronics utilizing digital signal processing
• Embedded systems needing reliable timing references

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Check manufacturer documentation for recommended soldering profiles to maintain component integrity during assembly processes.

Selection Notes

Select this component when a 19.2 MHz reference is required in a small form factor. Ensure the circuit design supports the specified 7 pF load capacitance. Consider the ±10 ppm tolerance against system timing requirements. Verify availability through authorized distributors to guarantee genuine product sourcing.

Part Context

This part belongs to NDK's standard crystal oscillator lineup, designed for general-purpose timing applications.
