9C16000016

Crystals Overview

The TXC Corporation 9C16000016 is a passive surface-mount quartz crystal resonator designed for frequency control applications. It operates at a nominal frequency of 16 MHz with a load capacitance of 32 pF and a frequency tolerance of ±30 ppm. The component features an equivalent series resistance (ESR) typically within standard limits for this package, housed in an HC-49/US SMD footprint measuring 11.4 mm x 4.8 mm. It supports a moisture sensitivity level (MSL) of Level 1 and complies with RoHS standards.

Crystals Feature Summary

• Surface-mount construction utilizing the HC-49/US package format for automated assembly integration
• Glass-sealed or hermetic-style stability ensuring consistent frequency performance under thermal stress
• Compliance with environmental directives including RoHS restrictions on hazardous substances

Crystals Applications

• Microcontroller clock source generation
• Communication module timing references
• Consumer electronic device oscillators

Crystals Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as datasheets may list variations such as 12pF or 32pF depending on the exact revision. Confirm the operating temperature range aligns with the application environment, noting that some sources indicate commercial ranges while others specify wider industrial limits. Ensure the supplier provides traceability documentation for RoHS compliance and MSL handling requirements prior to purchase.

Crystals Selection Notes

Select this component when a 16 MHz reference signal is required in a surface-mount layout constrained by the HC-49/US dimensions. Evaluate the 32 pF load capacitance compatibility with the oscillator circuit's stray capacitance to ensure accurate frequency tuning. Consider the ±30 ppm tolerance sufficient for general digital logic timing where high-precision metrology is not critical.

Crystals Part Context

This part belongs to the TXC 9C series of quartz crystals, which are widely used in consumer electronics for their balance of cost and performance. The manufacturer, TXC Corporation, specializes in frequency control products, offering both through-hole and surface-mount variants. This specific model represents a standard industry footprint solution for replacing older DIP crystals in modern PCB designs.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49S/SMD crystals rated at 16 MHz with 32 pF load capacitance. Verify pin compatibility and physical dimensions before swapping. Cross-reference ESR values and frequency stability specifications to ensure functional equivalence in the host oscillator circuit.
