CS14527-40M

Overview

The NDK CS14527-40M is a surface-mount crystal oscillator operating at a fundamental frequency of 40.0000 MHz. It features a load capacitance of 8 pF and a frequency stability of ±15 ppm. The component utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm x 0.60mm maximum height. It has an equivalent series resistance (ESR) of 50 Ohms and operates within a temperature range of -10°C to 75°C.

Feature Summary

• Surface-mount design in a compact 4-SMD no-lead package
• Fundamental mode operation for precise timing applications
• Compliant with RoHS standards and moisture sensitivity level 1

Applications

• Clock generation for microcontrollers and digital logic circuits
• Timing reference for communication interfaces requiring 40 MHz signals
• Embedded systems and consumer electronics utilizing SMD components

Procurement Notes

Verify the specific ordering suffix and packaging configuration required for your production line, such as tape and reel or cut tape options. Confirm that the 8 pF load capacitance matches your circuit design requirements. Ensure compatibility with the specified operating temperature range of -10°C to 75°C for your intended application environment before finalizing procurement.

Selection Notes

Select this component when a 40 MHz fundamental frequency crystal is required in a small form factor. The 8 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the ±15 ppm stability specification against your system's timing tolerance requirements. The 4-SMD package is suitable for automated surface-mount assembly processes.

Part Context

This part belongs to the NX3225SA series of surface-mount crystals from NDK. It shares the same physical footprint and general electrical characteristics with other frequencies in the series, differing primarily in resonant frequency and specific calibration data. It is designed for high-volume manufacturing applications requiring reliable timing sources.

Replacement Considerations

Direct substitutes include other NDK parts within the NX3225SA series with identical 40 MHz frequency and 8 pF load capacitance. Cross-manufacturer replacements must match the 3.2x2.5mm package size, 40 MHz frequency, 8 pF load capacitance, and ±15 ppm stability to ensure functional equivalence without layout changes.
