LFCN-1525+

Overview

The LFCN-1525+ is a low-pass filter manufactured by Mini-Circuits, designed for surface-mount applications. It operates from DC to 1525 MHz with a 50Ω impedance. The component utilizes LTCC technology and is housed in an FV1206 case style, measuring 3.2 mm x 1.6 mm x 0.94 mm. It features four terminals and supports an operating temperature range from -55°C to +100°C.

Feature Summary

• LTCC construction for compact surface-mount integration
• Low insertion loss characteristics within the passband
• High rejection performance above the cutoff frequency

Applications

• RF signal conditioning in communication systems
• Harmonic suppression in transmitter outputs
• Interference filtering in receiver front-ends

Procurement Notes

Verify the specific suffix (e.g., D+, AT+) against the required reel quantity or tape-and-reel specifications. Confirm the exact cutoff frequency tolerance and physical dimensions match the design constraints. Ensure the manufacturer source is Mini-Circuits to guarantee authenticity and datasheet accuracy.

Selection Notes

Select this component when a sharp cutoff near 1.5 GHz is required in a minimal footprint. The LTCC technology offers stability across wide temperature ranges. Compare insertion loss and stopband attenuation requirements against other Mini-Circuits filters in the same package size.

Part Context

This part belongs to Mini-Circuits' family of ceramic low-pass filters. It shares the FV1206 mechanical outline with other variants like the BFCN series but differs in frequency response characteristics. The '+' suffix indicates lead-free compliance according to RoHS standards.

Replacement Considerations

Direct substitutes include other Mini-Circuits LTCC low-pass filters in the FV1206 package, such as the LFCN-1500+ or LFCN-1600+, provided the cutoff frequency aligns with system requirements. Verify pinout compatibility before substitution.
