Resonators Procurement Notes

Verify the specific part number against official Murata documentation to confirm current availability status. Note that this component may be listed as discontinued or have limited regional distribution through certain distributors. Ensure the ordering suffix matches the required reel configuration and verify RoHS compliance details directly from the manufacturer's latest datasheet before procurement.

Resonators Selection Notes

Select this component when a precise 450 kHz reference is required for surface-mount designs. Consider the 6.5 mm x 6.5 mm footprint constraints during PCB layout. Evaluate thermal performance within the specified operating temperature range. Confirm compatibility with the target oscillator circuit requirements to ensure reliable operation without additional tuning components.

Resonators Part Context

This part is part of Murata's Cerafil line of ceramic resonators, which are widely used in consumer electronics and industrial equipment. It serves as an alternative to crystal units where cost-effective, robust frequency control is needed. The SMD form factor supports modern manufacturing processes.

Resonators Replacement Considerations

CSBFB453KJ58-R1 and CSBFB455KJ58-R1 are related parts within the same family but operate at different nominal frequencies (453 kHz and 455 kHz respectively). Direct substitution requires verifying if the slight frequency deviation is acceptable for the specific application timing requirements.
