Procurement Notes

Verify the specific datasheet version before procurement, as Taiyo Yuden updates specifications periodically. Confirm that the 5-SMD package dimensions match your PCB footprint requirements. Ensure compatibility with your assembly process for small-form-factor components. Cross-reference the part number suffixes to guarantee the correct attenuation type and packaging configuration intended for your production line.

Selection Notes

Select this component when designing circuits for GSM or cellular bands around 942.5 MHz. Its small 1.4x1.0 mm footprint makes it ideal for smartphones and tablets. Consider its 2 dB insertion loss for power efficiency needs. Verify that the 35 MHz bandwidth aligns with your system's channel requirements. Ensure the SMD termination style matches your manufacturing capabilities.

Part Context

This part belongs to Taiyo Yuden’s FAR series of passive filters, which includes SAW and FBAR technologies. These components are engineered for high-frequency applications in telecommunications. The series offers various form factors and performance levels to support different wireless standards.
