Procurement Notes

Verify the manufacturer designation carefully, as this component appears under both EPCOS (TDK) and Qualcomm branding in public databases. Confirm the specific datasheet version matches the required electrical parameters, particularly the 133.2 MHz center frequency and 10-terminal configuration. Ensure compliance with RoHS standards if required for the target assembly process.

Selection Notes

Select this component when a 133.2 MHz SAW filter is required for intermediate frequency stages in mobile or IoT devices. Consider the 10-pin SMD footprint and ceramic packaging constraints during PCB layout. Evaluate the 6 dB insertion loss against system link budget requirements. Verify thermal stability within the -30 °C to 80 °C range for the intended operational environment.

Part Context

This part belongs to the broader category of RF front-end filters used in wireless connectivity solutions. It serves as a discrete filtering element within modem-RF systems, supporting multimode operations across 4G and 5G networks. The component contributes to signal integrity in compact consumer electronics and infrastructure equipment requiring precise frequency selection.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 133.2 MHz center frequency, 10-SMD package dimensions, and SAW technology type.
