FCR8.0MC5

Resonators Overview

The FCR8.0MC5 is an obsolete through-hole ceramic resonator manufactured by TDK Corporation, designed for use in electronic circuits requiring stable frequency generation. It operates at a nominal frequency of 8 MHz with a tolerance of 0.5%. The component features a built-in capacitor and utilizes a three-pin termination style suitable for standard printed circuit board assembly. The maximum operating temperature rating is +85°C. This specific part number is no longer in production and has been discontinued by the manufacturer.

Resonators Feature Summary

• Utilizes thickness shear mode or third overtone thickness mode element technology for frequency stability
• Integrates a built-in capacitor to simplify circuit design and reduce component count
• Features a small leaded package structure optimized for surface mount or through-hole applications

Resonators Applications

• Microcontroller clock source circuits
• Simple oscillator circuits for consumer electronics
• Timing reference for low-cost digital systems

Resonators Procurement Notes

This component is officially marked as obsolete and no longer manufactured by TDK Corporation. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm that the inventory represents genuine TDK products rather than counterfeit alternatives, as availability is limited and supply chain verification is critical for quality assurance.

Resonators Selection Notes

Engineers replacing this obsolete part should evaluate alternative ceramic resonators from TDK's current FCR series or other manufacturers offering similar 8 MHz specifications. Key selection criteria include matching the frequency tolerance, ensuring compatible pin configurations, and verifying that the replacement supports the required operating temperature range. Design reviews should account for potential differences in equivalent series resistance and load capacitance values between legacy and modern components.

Resonators Part Context

The FCR8.0MC5 belongs to TDK's broader family of ceramic resonators, which are passive electronic components used primarily for timing and synchronization in digital circuits. These devices offer a cost-effective alternative to quartz crystals while providing reasonable frequency stability. The FCR series specifically targets applications where moderate precision is sufficient, leveraging ceramic materials to achieve the desired acoustic resonance properties within compact packages.

Resonators Replacement Considerations

No public confirmed substitute part numbers are available in official documentation. Engineers should consult TDK's current product catalogs for direct replacements or perform functional equivalence testing with generic 8 MHz ceramic resonators.
