CCR33.86MXC7T

Overview

The TDK CCR33.86MXC7T is a surface-mount ceramic resonator operating at a nominal frequency of 33.86 MHz. It features built-in loading capacitance of 8 pF, eliminating the need for external components. The device exhibits a frequency tolerance of ±0.5% and stability of ±0.2%, with an impedance of 40 Ohms. Designed for reliability, it operates within a temperature range of -40°C to +85°C. The component utilizes a 3-SMD non-standard package measuring 2.50mm x 2.00mm x 1.00mm.

Feature Summary

• Integrates piezoelectric elements onto a capacity-forming dielectric substrate to provide built-in loading capacitance.
• Utilizes thickness shear mode or 3rd over-tone thickness expansion element technology for stable oscillation.
• Optimized temperature characteristics ensure stable oscillating frequency across the operating range.
• Compatible with reflow soldering processes, including lead-free soldering conditions.

Applications

• Microcontroller clock sources
• Custom IC timing circuits
• Application-specific integrated circuit (ASIC) oscillators

Procurement Notes

Verify component obsolescence status prior to procurement, as this part is listed as obsolete with a specific end-of-life date. Confirm availability through authorized distributors or secondary market channels if production continuity is required. Ensure that the 3-SMD non-standard package dimensions align with existing PCB footprints. Validate that the ±0.5% frequency tolerance meets system requirements before finalizing orders.

Selection Notes

Select this component when a compact, low-component-count solution is needed for fixed-frequency applications. The built-in 8 pF capacitance simplifies circuit design by removing external load capacitors. Consider the 40 Ohm impedance and 33.86 MHz frequency for compatibility with target oscillator circuits. The thin-type SMD form factor suits space-constrained designs requiring reflow soldering compatibility.

Part Context

This part belongs to the TDK CCR series of thin-type ceramic chip resonators. The series offers various frequencies and packages, utilizing either thickness shear or 3rd over-tone modes depending on the frequency band. This specific model targets the 16.0 to 50.0 MHz range, providing a cost-effective alternative to quartz crystals in consumer electronics and industrial control systems where moderate stability suffices.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. As the component is marked obsolete, engineers must evaluate equivalent ceramic resonators from other manufacturers or newer TDK series parts with compatible frequency, package, and electrical specifications.
