Procurement Notes

Verify the specific datasheet version from Shenzhen Sunlord Electronics Co., Ltd. to confirm electrical tolerances and pin configurations. Ensure compatibility with balanced circuit designs requiring differential filtering at 2.45GHz. Confirm that the 0805 package dimensions align with the target PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when a balanced filter topology is required for 2.45GHz signals. The 100MHz bandwidth suits narrowband ISM applications. Compare insertion loss specifications against system link budget requirements. Ensure the design supports differential signaling to utilize the balanced nature of the filter effectively.

Part Context

This part belongs to Sunlord's RF filter portfolio, which includes various chip components for communications and consumer electronics.
