LNCD1-27M

Overview

The LNCD1-27M is a surface-mount crystal resonator manufactured by NDK. It operates at a fundamental frequency of 27 MHz with a load capacitance of 8 pF. The unit provides a frequency stability of ±50 ppm and features an equivalent series resistance (ESR) of 70 Ohms. It utilizes a 2-SMD, no-lead package with dimensions of 5.00 mm in length and 3.20 mm in width. The component supports base harmonic operation and is designed for standard surface-mount installation processes.

Feature Summary

• Fundamental mode crystal oscillation
• Compact 2-SMD surface-mount footprint
• Standard 8 pF load capacitance configuration

Applications

• Clock signal generation for microcontrollers
• Frequency reference for communication modules
• Timing circuits in consumer electronics

Procurement Notes

Verify the specific package variant against the official datasheet to ensure compatibility with PCB footprints. Confirm that the 70 Ohm ESR aligns with the oscillator circuit design requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the 27 MHz frequency matches the system clock specifications exactly.

Selection Notes

Select this component when a 27 MHz fundamental frequency is required with moderate stability. The 70 Ohm ESR suits standard oscillator topologies. The 2-SMD package offers space efficiency compared to larger 4-terminal variants. Verify that the ±50 ppm stability meets the application's timing tolerance needs before integration into the design.

Part Context

This part belongs to the NDK crystal resonator family, specifically designed for surface-mount applications. It serves as a passive frequency-determining element in electronic circuits. The 27 MHz output is commonly used in radio frequency and digital timing applications. The manufacturer ensures consistency through controlled manufacturing processes for the NX series components.

Replacement Considerations

Direct substitutes include other 27 MHz crystals with identical 8 pF load capacitance and similar ESR values. Verify package dimensions match the existing footprint. Cross-reference with NDK's NX series or comparable industry-standard SMD crystals. Ensure the replacement maintains the same fundamental mode operation.
