1175LP15A0550001E

Overview

The Johanson Technology 1175LP15A0550001E is a surface-mount low-pass RF filter designed for signal conditioning applications. It operates within a frequency range of 900 MHz to 1450 MHz, centered at 1.175 GHz. The component features a 50-ohm impedance and is housed in an 0805 (2012 metric) package with SMD/SMT termination. It exhibits an insertion loss of 2.5 dB and a return loss of 9.5 dB. The device supports a power handling capacity of 1W and functions reliably between -40°C and +85°C.

Feature Summary

• Provides effective high-frequency signal attenuation above the passband while maintaining low insertion loss within the operational range.
• Utilizes a compact 0805 surface-mount footprint suitable for space-constrained printed circuit board layouts.
• Constructed with Ni/Sn terminations compliant with RoHS standards for environmental safety.

Applications

• Wireless communication systems requiring band-specific filtering
• RF front-end modules in mobile devices
• Signal conditioning in industrial control equipment

Procurement Notes

Verify the complete part number including the suffix '001E' to ensure correct packaging and termination specifications. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the operating temperature range meets your system's environmental conditions.

Selection Notes

Select this component when a low-pass filter with a cutoff near 1.45 GHz is required for 50-ohm systems. Consider the 0805 package size for assembly compatibility. Evaluate the 2.5 dB insertion loss against system sensitivity requirements. Verify that the 1W power rating exceeds the maximum expected signal power in the application path.

Part Context

This component belongs to Johanson Technology's LP series of low-pass filters. These filters are engineered for radio frequency applications where harmonic suppression or out-of-band interference rejection is necessary. The series offers various cutoff frequencies and package sizes to accommodate different design constraints.

Replacement Considerations

No public substitute part numbers are confirmed for this specific model. Cross-referencing requires matching the 900-1450 MHz frequency range, 0805 package, and 50-ohm impedance characteristics precisely.
