PBRC4.91HR10X000

Resonators Overview

The PBRC4.91HR10X000 is a ceramic resonator manufactured by KYOCERA AVX, designed for surface-mount applications. It operates at a nominal frequency of 4.91 MHz with a tolerance of ±0.5%. The component features an integrated load capacitance of 30 pF and utilizes a three-pin SMD package measuring 7.4 mm in length, 3.4 mm in width, and 2 mm in height. It is rated for operation within a temperature range of -40°C to +85°C.

Resonators Feature Summary

• Surface-mount ceramic resonator construction
• Integrated 30 pF load capacitance
• Three-terminal SMD package design

Resonators Applications

• Clock signal generation for microcontrollers
• Timing circuits in consumer electronics
• Frequency reference for communication modules

Resonators Procurement Notes

Verify the specific suffix '10' indicates the 30 pF internal capacitance configuration distinct from other variants like '50'. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure soldering profiles align with the specified thermal limits for the 7.4 x 3.4 mm package dimensions.

Resonators Selection Notes

Select this component when a precise 4.91 MHz timing source with built-in 30 pF loading is required. Consider the ±0.5% frequency tolerance for applications demanding high accuracy. Evaluate the 3-pin SMD form factor against available PCB real estate constraints compared to larger through-hole alternatives.

Resonators Part Context

This part belongs to the PBRC series of ceramic resonators from KYOCERA AVX. These devices serve as cost-effective alternatives to quartz crystals by integrating the necessary capacitive elements directly into the package. The series supports various frequencies and capacitance values for diverse embedded system requirements.

Resonators Replacement Considerations

Direct substitutes include PBRC4.91HR50X000 (10 pF) or PBRCV4.91HR50Y000 if different capacitance is acceptable. Verify pinout compatibility and physical footprint alignment before swapping components in existing designs.
