CS05116-16M

Overview

The CS05116-16M is a surface-mount MHz crystal unit manufactured by NDK. It operates at a fundamental frequency of 16 MHz with a frequency stability and tolerance of ±15 ppm. The component features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm x 0.55mm. Designed for base harmonic operation, it supports a working temperature range of -10°C to +75°C and meets RoHS standards.

Feature Summary

• Compact thin package design measuring 3.2mm x 2.5mm x 0.55mm
• Resistant to heat, vibration, and shock
• Base harmonic operation mode for stable oscillation

Applications

• Zigbee short-range wireless communication nodes
• Industrial low-power embedded systems
• Microcontroller reference clock sources

Procurement Notes

Verify the specific load capacitance requirement of the target oscillator circuit against the component's 12pF specification to ensure frequency accuracy. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions. Check compatibility with the operating temperature range of -10°C to +75°C for the intended application environment. Ensure compliance with RoHS regulations if required by the final product specifications.

Selection Notes

Select this component when a compact, shock-resistant crystal is needed for 16 MHz applications. It is suitable for designs requiring ±15 ppm stability within a limited temperature range. Consider the 80 Ohm ESR value when designing the oscillator circuit to guarantee reliable start-up. The small form factor makes it ideal for space-constrained PCB layouts in portable or industrial devices.

Part Context

This part belongs to the NX3225SA series of crystal units from NDK. The series is characterized by its thin profile and robust mechanical construction. It serves as a precise timekeeping element for digital circuits requiring a stable 16 MHz reference signal. The component is widely used in modern electronics where size and reliability are critical constraints.

Replacement Considerations

The part number alias NX2520SA-16MHZ-EXS00A-CS05116 refers to the same component. Verify pin compatibility and electrical parameters before substituting with other 16 MHz crystals from different manufacturers.
