ZFBP-400K-S+

Overview

The ZFBP-400K-S+ is a lumped LC bandpass filter designed for radio frequency applications. It operates with a center frequency of 400 kHz and provides a bandwidth of 100 kHz, covering the range from 0.35 to 0.45 MHz. The component features a characteristic impedance of 50 Ohms and utilizes SMA connectors for interface connectivity. It is housed in a rugged connectorized package measuring 1.25 inches by 1.25 inches by 0.75 inches, ensuring reliable performance in signal conditioning tasks.

Feature Summary

• Lumped LC construction for effective signal filtering
• SMA connectorized interface for secure attachment
• Rugged physical housing for durability

Applications

• Radio frequency signal conditioning
• Intermediate frequency filtering
• Communication system channel selection

Procurement Notes

Verify the specific suffix designation against official Mini-Circuits documentation to confirm exact electrical tolerances and connector types. Ensure compatibility with 50 Ohm system impedance requirements. Cross-reference part numbers carefully as minor variations may exist between standard and specialized versions. Confirm package dimensions match enclosure constraints before integration into final designs.

Selection Notes

Select this component when a narrow 100 kHz bandwidth centered at 400 kHz is required. The 50 Ohm impedance matches standard RF transmission lines. Consider the physical size of the connectorized package during layout planning. Verify that the lumped LC topology meets the specific insertion loss and rejection specifications needed for the target application environment.

Part Context

This model belongs to the ZFBP series of connectorized bandpass filters manufactured by Mini-Circuits. The series covers various frequency ranges using lumped element technologies. The ZFBP-400K-S+ specifically addresses low-frequency RF needs where precise channel isolation is critical. It represents a standardized solution for integrating filtering capabilities directly into RF signal paths.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Generic equivalents may not maintain identical impedance matching or physical footprint. Ensure any substitute supports the same SMA interface and 50 Ohm specification without altering system performance characteristics.
