CS14516-27.12M

Overview

The NDK CS14516-27.12M is a surface-mount piezoelectric crystal unit operating at a nominal frequency of 27.12 MHz. It belongs to the NX3225SA series and utilizes a 4-SMD, no-leads package with dimensions of 3.20mm x 2.50mm x 0.60mm maximum height. The component features a load capacitance of 8pF and an equivalent series resistance (ESR) of 50 Ohms. Frequency tolerance is specified at ±15ppm, with stability also rated at ±15ppm. It supports fundamental mode operation within a temperature range of -10°C to +75°C.

Feature Summary

• Compact 3.2x2.5mm surface-mount footprint suitable for space-constrained PCB layouts
• Fundamental resonance mode operation ensuring stable oscillation characteristics
• RoHS compliant construction supporting environmental regulatory standards

Applications

• Automotive electronic systems requiring precise timing references
• Mobile communication devices utilizing standard RF frequencies
• Office automation equipment including printers and scanners
• Audiovisual hardware components needing clock synchronization

Procurement Notes

Verify the specific suffix codes against official NDK documentation to ensure correct packaging and tolerance specifications. Confirm that the intended application environment remains within the stated -10°C to +75°C operational limits. Check for RoHS compliance requirements if exporting to regulated regions. Ensure ESR compatibility with the host oscillator circuit design before finalizing procurement orders.

Selection Notes

Select this component when a 27.12 MHz reference is required for automotive or consumer electronics. The 8pF load capacitance dictates specific external capacitor values for circuit tuning. Consider the 50 Ohm ESR limit to ensure reliable start-up conditions. Evaluate thermal constraints as the upper limit is +75°C, which may require derating for high-temperature industrial environments.

Part Context

This crystal unit is part of the NX3225SA series designed by NDK for general-purpose timing applications. The series targets markets such as automotive, mobile communications, and office automation. It provides a standardized solution for integrating quartz resonators into modern surface-mount assembly processes while maintaining consistent electrical performance across production batches.

Replacement Considerations

Cross-reference with other NX3225SA variants for different frequencies or tolerances. Verify pinout and mechanical dimensions match existing footprints. Ensure load capacitance and ESR parameters align with current oscillator designs to prevent frequency drift or failure to start.
