Procurement Notes

Verify part authenticity through authorized TDK distributors or official channels. Confirm that the specific suffix UC8T matches the required package and pin configuration for your PCB layout. Check current availability status as this component may be classified as obsolete in some catalogs; ensure alternative sourcing strategies are in place if supply chain continuity is critical for production.

Selection Notes

Select this component when a compact, low-profile resonator with integrated capacitance is required for 4.0 MHz applications. The 3-SMD form factor suits space-constrained designs. Ensure the -40°C to +85°C temperature range aligns with the environmental conditions of the target application. Verify that the internal capacitance values meet the load requirements of the connected oscillator circuit without additional external components.

Part Context

This part belongs to the TDK CCR series of thin-type ceramic chip resonators. The series employs thickness shear mode elements for frequencies between 4.0 and 11.0 MHz. These devices are characterized by their small footprint and simplified circuit integration due to built-in loading capacitors, making them suitable for modern surface-mount assembly processes in consumer and industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the CCR4.0MUC8T is listed as obsolete, consult TDK technical support for direct replacements or equivalent series members within the CCR-MUC family that match the 4.0 MHz frequency and 3-SMD package constraints.
