Procurement Notes

This component is classified as obsolete by the manufacturer. Procurement requires verification of availability through secondary market channels or authorized distributors holding remaining stock. Buyers should confirm the physical condition and authenticity of units prior to purchase, as standard manufacturing supply has ceased.

Selection Notes

Engineers requiring this specific attenuation profile must account for the discontinued status during design finalization. Alternative components with identical 10dB attenuation, 50 Ohm impedance, and SMA interfaces should be evaluated for compatibility. Ensure that any substitute part meets the 3 GHz frequency limit and 1W power rating requirements of the original specification.

Part Context

This part belongs to the category of RF/IF and RFID attenuators manufactured by Seeed Technology Co., Ltd. It serves as a passive component for managing signal strength in radio frequency environments. The product is distinct from active amplifiers or variable attenuators, offering a static reduction in signal amplitude.
