CSTNE18M4V53L00ZR0

Resonators Overview

The Murata Electronics CSTNE18M4V53L00ZR0 is a CERALOCK ceramic resonator designed for surface-mount applications. It operates at a nominal frequency of 18.432 MHz with a frequency stability of ±0.2% and a tolerance of ±0.5%. The component features an integrated load capacitance of 15 pF, eliminating the need for external capacitors in typical oscillator circuits. It utilizes SMD/SMT termination types and is housed in a compact 3.2 mm x 1.3 mm x 0.9 mm package. The device supports a wide operating temperature range from -40°C to +125°C and has a maximum impedance of 40 Ohms.

Resonators Feature Summary

• Integrates built-in load capacitors to simplify circuit design
• Provides high frequency stability within a compact surface-mount footprint
• Operates reliably across extended industrial temperature ranges

Resonators Applications

• Microcontroller clock sources
• Communication module timing circuits
• Embedded system oscillators

Resonators Procurement Notes

Verify that the specific suffix L00Z corresponds to the required packaging configuration and tape width for your automated assembly equipment. Confirm that the 15 pF internal capacitance aligns with the host oscillator circuit requirements without additional external components. Ensure the 40 Ohm impedance specification is compatible with the driving gate voltage limits of the target microcontroller or logic family.

Resonators Selection Notes

Select this component when a precise 18.432 MHz reference is required with minimal external passive components. The integrated capacitor design reduces board space and assembly complexity compared to discrete crystal setups. Consider the ±0.2% stability for applications requiring tighter timing accuracy than standard ±0.5% tolerances allow. Evaluate the 3.2x1.3mm package size against available PCB real estate constraints.

Resonators Part Context

This part belongs to Murata's CERALOCK CSTNE series, which specializes in small-cap chip type ceramic resonators. These devices are engineered to replace traditional quartz crystals in cost-sensitive and space-constrained designs. The series offers various frequencies and package sizes, providing a standardized solution for general-purpose timing needs in consumer and industrial electronics.

Resonators Replacement Considerations

Direct substitutes must match the 18.432 MHz frequency, 15 pF internal capacitance, and 3.2x1.3mm package dimensions. Verify equivalent impedance and temperature stability ratings. Cross-reference alternative manufacturers' ceramic resonators with identical electrical characteristics and mounting footprints.
