CCR8.0MXC8WT

Overview

The CCR8.0MXC8WT is an 8 MHz ceramic resonator manufactured by TDK Corporation, designed for surface-mount applications. It features a built-in capacitor configuration with a capacitance of 18 pF and a frequency stability of ±0.3%. The component exhibits an impedance of 40 Ohms and operates within a temperature range of -40°C to 105°C. Packaged in a 3-SMD non-standard form factor measuring 3.20mm x 1.25mm, it provides a compact solution for clock generation circuits requiring precise timing without external tuning components.

Feature Summary

• Integrated built-in capacitor design eliminates the need for external load capacitors
• High frequency stability ensures reliable clock signal generation
• Surface-mount package facilitates automated assembly processes

Applications

• Microcontroller clock sources
• Digital signal processing circuits
• Communication interface timing

Procurement Notes

Verify that the specific part number matches the required frequency and tolerance specifications before integration. Confirm that the surface-mount footprint dimensions align with the PCB layout constraints. Ensure that the operating temperature range meets the environmental requirements of the final application. Check for RoHS compliance status if restricted substance regulations apply to the manufacturing process.

Selection Notes

Choose this component when a cost-effective, space-saving timing solution is required for standard digital logic applications. The built-in capacitor feature simplifies circuit design by reducing component count. Consider the ±0.3% stability for applications where moderate precision is sufficient. Evaluate the 40 Ohm impedance against the driving capability of the target oscillator circuit to ensure proper oscillation startup.

Part Context

This ceramic resonator belongs to TDK's line of passive electronic components focused on timing and filtering solutions. Ceramic resonators offer a balance between performance and cost compared to quartz crystals, making them suitable for consumer electronics and industrial equipment where extreme stability is not critical. The SMD format supports modern high-density board designs.

Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 18 pF internal capacitance, and 40 Ohm impedance. Verify that alternative manufacturers provide equivalent frequency stability and temperature ranges. Ensure the replacement component fits the same 3-SMD non-standard package dimensions to maintain mechanical compatibility.
