Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance status prior to final procurement approval.

Selection Notes

Select this component when a 2.45 GHz center frequency with narrow 100 MHz bandwidth is required. The low insertion loss supports efficient power transmission, while the specified attenuation ensures effective interference suppression in crowded RF environments.

Part Context

This part belongs to the SLFB series of multilayer chip LC bandpass filters from Shenzhen Sunlord Electronics. These components are engineered for RF applications requiring precise frequency selection and harmonic suppression in compact form factors suitable for modern electronic devices.

Replacement Considerations

Consult official substitution lists for equivalent LTCC bandpass filters with matching 2.45 GHz specifications. Verify that alternative parts maintain identical footprint dimensions and thermal characteristics to ensure seamless board integration.
