CSTLS18M0X51-A0

Resonators Overview

The Murata CSTLS18M0X51-A0 is a ceramic resonator from the CERALOCK series, designed for through-hole mounting. It operates at a nominal frequency of 18 MHz with a tolerance of ±0.5%. The component features an integrated load capacitance of 5 pF and a maximum impedance of 50 Ohms. It functions within an operating temperature range of -20°C to +80°C. The device utilizes third harmonic oscillation mode and includes built-in capacitors to simplify circuit design.

Resonators Feature Summary

• Integrates built-in capacitors to reduce external component count
• Supports third harmonic oscillation mode for stable frequency generation
• Through-hole package construction for reliable board attachment

Resonators Applications

• Microcontroller clock sources
• General-purpose timing circuits
• Consumer electronics control boards

Resonators Procurement Notes

Verify the specific suffix 'A0' against the official Murata datasheet to confirm packaging details and pin configuration. Ensure the selected variant matches the required 5 pF load capacitance and 50 Ohm impedance specifications for the target application. Cross-reference the RoHS compliance status with current regulatory requirements before finalizing procurement orders.

Resonators Selection Notes

Select this component when a cost-effective timing solution with integrated capacitance is required. The 18 MHz frequency suits applications needing moderate speed without the precision of quartz crystals. Verify that the PCB footprint accommodates the through-hole dimensions and that the operating temperature range meets environmental constraints.

Resonators Part Context

This part belongs to the CSTLS_X series of ceramic resonators manufactured by Murata Electronics. These components are widely used in digital circuits where precise frequency stability is less critical than in quartz-based systems. The CERALOCK branding indicates a focus on compact size and ease of integration into standard electronic assemblies.

Resonators Replacement Considerations

Direct substitutes include other Murata ceramic resonators with identical 18 MHz frequency, 5 pF load capacitance, and through-hole packaging. Verify that alternative parts maintain the same 50 Ohm impedance and third harmonic operation characteristics to ensure circuit compatibility.
