CSTCE12M5G55-R0

Resonators Overview

The Murata Electronics CSTCE12M5G55-R0 is a ceramic resonator from the CERALOCK CSTCE series, designed for surface-mount applications. It operates at a nominal frequency of 12.5 MHz with an initial tolerance of ±0.5% and a frequency stability of ±0.2%. The component features a built-in load capacitance of 33 pF, eliminating the need for external capacitors in oscillator circuits. It is housed in a compact 3.20 mm x 1.30 mm x 0.79 mm SMD package and supports operation within a temperature range of -20°C to +80°C.

• High vibration resistance ensuring reliable performance in portable devices

Resonators Applications

• Microprocessor clock oscillators
• Electronic control circuits in handheld cameras and small electronic devices
• Audio and visual equipment such as camcorders and remote controls
• Office automation devices including DVD, CD-ROM, HDD, and FDD systems

Resonators Procurement Notes

This specific part number is officially classified as obsolete and no longer manufactured by Murata Electronics. Procurement should focus on verified replacement components rather than sourcing this discontinued item. Buyers must confirm availability through authorized distributors who may hold remaining stock or offer direct substitutes. Verify that any alternative component matches the required electrical specifications and physical footprint to ensure seamless integration into existing designs without modification.

Resonators Selection Notes

Designers requiring a 12.5 MHz ceramic resonator with similar characteristics should evaluate the CSTNE series as a primary alternative. The CSTNE12M5G55Z000R0 offers comparable frequency and capacitance but provides an extended operating temperature range of -40°C to +125°C. Selection criteria should prioritize thermal requirements and supply chain stability. Engineers must verify pin compatibility and circuit tuning adjustments when transitioning from the obsolete CSTCE series to newer generations to maintain system performance.

Resonators Part Context

The CSTCE12M5G55-R0 belongs to the CERALOCK family of ceramic resonators, which are piezoelectric devices used to provide stable frequency references in digital circuits. This series was widely adopted in consumer electronics due to its low cost and ease of use compared to quartz crystals. As a third-generation product, it represents Murata's effort to miniaturize resonator technology while maintaining high reliability standards for mass-produced electronic goods.

Resonators Replacement Considerations

The confirmed substitute part number is CSTNE12M5G55Z000R0. This replacement maintains the 12.5 MHz frequency and 33 pF internal capacitance but expands the operational temperature range. Verification of mechanical fit and electrical performance in the target application is required before implementation.
