17161

Crystals Overview

The Crystek Corporation part number 17161 is a fundamental crystal resonator designed for surface-mount technology applications. It operates at a precise frequency of 9.494531 MHz, utilizing the HC49S package form factor adapted for SMD integration. This component serves as a basic frequency reference element within electronic circuits, providing stable oscillation without internal active drive circuitry. The device is characterized by its specific mechanical dimensions and electrical properties suitable for standard crystal oscillator designs.

Crystals Feature Summary

• Surface-mount configuration compatible with automated assembly processes
• Fundamental mode crystal resonator operation
• HC49S package style optimized for compact PCB layouts

Crystals Applications

• General-purpose clock generation in digital logic circuits
• Frequency reference input for microcontroller systems
• Timing source for communication interface modules

Crystals Procurement Notes

Verify that the required load capacitance matches the system design specifications, as this is a passive crystal requiring external capacitors. Confirm the operating temperature range aligns with the environmental conditions of the target application. Ensure the soldering profile adheres to the thermal limits specified in the official datasheet to prevent mechanical stress or frequency drift during reflow processes.

Crystals Selection Notes

Select this component when a fundamental frequency near 9.5 MHz is required for timing references. Consider the HC49S footprint constraints and available board space. Evaluate the need for additional filtering or buffering stages based on the noise sensitivity of the downstream circuitry. Compare against other Crystek series if different frequencies or package types are necessary for the specific design requirements.

Crystals Part Context

This part belongs to the Crystek Corporation family of fundamental crystal resonators. Unlike voltage-controlled or buffered oscillators, it provides raw frequency stability dependent on external circuit components. It is distinct from higher-frequency XO series such as CCPD-033, which integrate active electronics and LVPECL outputs for direct digital interfacing.

Crystals Replacement Considerations

Direct substitutes must match the 9.494531 MHz frequency and HC49S SMD footprint. Verify equivalent load capacitance and ESR values. Cross-reference with other manufacturers offering HC49S-4 or similar SMD crystal packages ensuring identical frequency tolerance and stability ratings.
