Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape-and-reel or cut tape, as these affect handling but not electrical function. Confirm that the application environment remains within the specified operating temperature limits. Check for any recent Product Change Notifications regarding material or dimensional updates before finalizing procurement plans.

Selection Notes

Select this component when a 5.41GHz center frequency with 1.02GHz bandwidth is required in a 0805 footprint. Ensure the system impedance matches the filter's design characteristics. Consider the 1.5dB insertion loss impact on overall link budget. Verify that the physical dimensions fit within the constrained PCB area allocated for RF components.

Part Context

This part belongs to the WE-BPF series of multilayer chip band-pass filters manufactured by Würth Elektronik. These components are engineered for high-frequency applications requiring compact form factors. The series offers various center frequencies and bandwidths to suit different RF spectrum requirements while maintaining consistent mechanical and electrical standards across the product line.

Replacement Considerations

Johanson Technology Inc. part number 5515BP15C1020001E is listed as a similar alternative. Verify electrical compatibility, specifically center frequency and bandwidth alignment, before substitution. Physical footprint and pin configuration must be confirmed to ensure direct board replacement without layout modifications.
