CS00469-26M

Overview

The CS00469-26M is a surface-mount quartz crystal resonator manufactured by NDK. It operates at a fundamental frequency of 26 MHz with a load capacitance of 10 pF. The component exhibits a frequency tolerance of ±10 ppm and a stability of ±25 ppm across the operating temperature range of -40°C to +85°C. It features an equivalent series resistance (ESR) of 50 Ohms maximum. The device utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.60mm. It supports base harmonic operation mode.

Feature Summary

• Provides precise timing signals for digital circuits through stable oscillation at 26 MHz.
• Designed for surface-mount assembly to facilitate automated PCB placement.
• Maintains frequency accuracy within tight tolerances across industrial temperature ranges.

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify the specific load capacitance requirement of the target circuit matches the 10 pF specification of this component. Ensure the PCB footprint aligns with the 4-SMD no-lead package dimensions. Confirm that the operating environment falls within the specified -40°C to +85°C range to guarantee performance reliability. Check for RoHS compliance status if required by project regulations.

Selection Notes

Select this component when a 26 MHz fundamental frequency crystal is required for space-constrained designs. The 4-SMD package offers a compact form factor suitable for high-density layouts. Consider the ±10 ppm tolerance for applications demanding higher precision than standard ±20 ppm crystals. Evaluate the ESR value against the oscillator circuit's drive level capabilities to ensure proper startup and stability.

Part Context

This part belongs to NDK's general-purpose SMD crystal lineup. It serves as a passive frequency-determining element in electronic circuits. Unlike active oscillators, it requires an external oscillator circuit to generate a square wave output. It is distinct from toggle switches or other electromechanical components also produced by the manufacturer.

Replacement Considerations

Substitute parts must match the 26 MHz frequency, 10 pF load capacitance, and 4-SMD package size. Verify that alternative manufacturers provide comparable ESR and stability specifications. Ensure the replacement component supports the same operating temperature range and mounting orientation.
