LFCN-1325+

Overview

The LFCN-1325+ is a surface-mount low-pass filter manufactured by Mini-Circuits, designed for signal conditioning applications. It operates within a frequency range of 0 Hz to 1.325 GHz and features a nominal impedance of 50 ohms. The component utilizes LTCC technology housed in a compact 1206 (3216 metric) package with SMD/SMT termination. It exhibits excellent power handling capabilities of 9W and maintains temperature stability across an operating temperature range from -55°C to +100°C.

Feature Summary

• LTCC structure providing temperature stability
• High power handling capability
• Compact surface-mount form factor

Applications

• Harmonic suppression
• VHF transmitter systems
• UHF receiver systems

Procurement Notes

Verify the specific ordering suffix against official Mini-Circuits documentation to ensure correct configuration. Confirm that the required packaging format matches current availability, as reel specifications may vary. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical compliance before procurement.

Selection Notes

Select this component for designs requiring a low-pass filter up to 1.325 GHz with high power tolerance. Ensure the PCB layout accommodates the 1206 footprint and ground connections. Verify that DC blocking capacitors are included if DC voltage is present at ports, as specified in application guidelines.

Part Context

This device belongs to the LFCN series of ceramic filters from Mini-Circuits. These components are engineered for RF and microwave signal processing tasks. The series offers various cutoff frequencies while maintaining consistent impedance and package dimensions for design flexibility.

Replacement Considerations

Consult Mini-Circuits official substitution guides for verified alternatives. Do not assume compatibility based on similar cutoff frequencies alone; verify impedance, power handling, and physical dimensions.
