Procurement Notes
Verify the specific datasheet revision and RoHS compliance status directly with Walsin or authorized distributors before procurement. Confirm that the 0603 package dimensions align with your PCB footprint requirements. Ensure the 2.45 GHz center frequency matches your system's operational band to avoid signal degradation or interference issues during integration.
Selection Notes
Select this component when a compact, low-profile bandpass filter is required for 2.4 GHz wireless applications. The 0603 size suits space-constrained designs. Consider the 2.5 dB bandwidth specification to ensure it meets the spectral mask requirements of your communication protocol. Verify impedance matching with surrounding circuitry to minimize reflection losses.
Part Context
This part belongs to the RFBPF series of multilayer ceramic bandpass filters from Walsin. These components are specifically designed to pass frequencies within defined ranges while attenuating out-of-band signals. The series supports various RF applications requiring reliable signal integrity in compact electronic devices.
Replacement Considerations
