LP0805A0947ASTR

Overview

The KYOCERA AVX LP0805A0947ASTR is a surface-mount low-pass filter designed for signal conditioning applications. It operates at a cutoff frequency of 947 MHz with a specified bandwidth of 25 MHz. The component features a 50 Ohm impedance and utilizes an SMD/SMT termination type within an 0805 (2012 metric) package. It exhibits an insertion loss of 0.3 dB and functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

• Provides effective high-frequency signal attenuation above the 947 MHz cutoff point
• Optimized for minimal signal degradation with low insertion loss characteristics
• Designed for compact board mounting in space-constrained electronic assemblies

Applications

• RF signal conditioning circuits
• Harmonic suppression in communication systems
• Base station filtering applications

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status prior to procurement, as manufacturing specifications may evolve. Confirm that the 0805 footprint matches your PCB layout constraints. Ensure the operating temperature range meets your environmental requirements. Cross-reference the part number suffix to confirm the exact packaging configuration intended for your assembly process.

Selection Notes

Select this component when a precise 947 MHz cutoff is required for low-pass filtering tasks. The 0805 package size offers a balance between performance and board space efficiency. Consider the 50 Ohm system impedance compatibility for standard RF designs. Evaluate the thermal stability requirements against the specified -40°C to +85°C operational range before finalizing the design choice.

Part Context

This component belongs to the LP series of low-pass filters manufactured by KYOCERA AVX. These devices are engineered for radio frequency signal processing and conditioning. The series provides various cutoff frequencies tailored for different communication standards. The LP0805A0947ASTR specifically targets applications requiring filtering near the 1 GHz threshold.

Replacement Considerations

Consult official substitution guides for compatible alternatives. Verify electrical parameters such as cutoff frequency, impedance, and insertion loss match the original design requirements. Ensure physical dimensions and pin configurations are identical for direct replacement without PCB redesign.
