9C04070006

Crystals Overview

The TXC Corporation 9C04070006 is a 4.0000 MHz fundamental mode quartz crystal resonator designed for surface-mount applications. It features an 18 pF load capacitance and operates within a frequency tolerance of ±30 ppm. The component exhibits an equivalent series resistance (ESR) of 150 Ohms and utilizes the HC-49/US package style, which is adapted for SMD mounting. It supports standard drive levels and provides stable oscillation across industrial temperature ranges.

Crystals Feature Summary

• Fundamental mode quartz crystal operation
• Surface-mount compatible HC-49/US package design
• Stable frequency generation with 18 pF load capacitance

Crystals Applications

• Microcontroller clock circuits
• Digital communication interfaces
• General-purpose timing references

Crystals Procurement Notes

Verify the specific package variant when sourcing, as the HC-49/US designation typically implies through-hole but this model is specified for SMD use. Confirm RoHS compliance status directly with the manufacturer or authorized distributors to ensure adherence to environmental regulations required for modern electronics assembly processes.

Crystals Selection Notes

Select this component when a 4 MHz reference is required in a compact surface-mount form factor. Ensure the host circuit is designed to support the 150 Ohm ESR characteristic. Verify that the system load capacitance matches the 18 pF specification to maintain accurate frequency stability during operation.

Crystals Part Context

This part belongs to the broad category of quartz crystal resonators manufactured by TXC Corporation. It serves as a passive timing element essential for synchronizing digital logic states. The 4 MHz frequency is commonly utilized in legacy systems, simple microcontrollers, and basic serial communication protocols requiring precise baud rate generation.

Crystals Replacement Considerations

Cross-reference with other 4 MHz SMD crystals from TXC having similar ESR and load capacitance values. Ensure any substitute maintains the same physical footprint and electrical parameters to guarantee compatibility with existing PCB layouts and oscillator circuits.
