BP0805A1481ASTR

Overview

The BP0805A1481ASTR is a bandpass RF filter manufactured by KYOCERA AVX, designed for signal conditioning applications. It operates at a center frequency of 1481 MHz with a 50-ohm impedance. The component utilizes a surface-mount 0805 (2012 metric) package, measuring 2.03mm in length and 1.55mm in width. It supports board mounting and functions within an operating temperature range of -40°C to +85°C. The device is RoHS compliant and features low insertion loss characteristics typical of the MLO™ series.

Feature Summary

• High-performance surface-mount bandpass filter design
• Low insertion loss and steep roll-off characteristics
• High rejection of out-of-band signals
• Compact 0805 footprint for space-constrained layouts

Applications

• Wireless communication systems requiring precise frequency selection
• RF front-end modules for mobile devices
• Signal conditioning in broadband infrastructure equipment
• Applications demanding high out-of-band rejection

Procurement Notes

Verify the specific datasheet version and manufacturing origin before procurement. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Ensure compatibility with standard SMD reflow soldering profiles. Check for any recent product change notices (PCNs) regarding material composition or assembly location changes. Validate RoHS compliance status against current regulatory standards for your target market.

Selection Notes

Select this component when a 1481 MHz center frequency is required for bandpass filtering. The 0805 package size offers a balance between performance and board space efficiency. Consider the 50-ohm impedance match for system integration. Evaluate the thermal operating range of -40°C to +85°C against environmental conditions. Compare insertion loss specifications with other filters in the BP series if stricter attenuation is needed.

Part Context

This part belongs to the KYOCERA AVX BP series of MLO™ bandpass filters. These components are thin-film surface-mount devices engineered for RF applications. The series is known for consistent performance across various wireless standards. The BP0805A1481ASTR specifically targets frequencies around 1.48 GHz, fitting into the broader portfolio of precision RF filters offered by the manufacturer.

Replacement Considerations

Direct substitutes within the same series include BP0805A1457ASTR and BP0805A1308ASTR, though these operate at different center frequencies. Verify that any replacement maintains the 0805 package outline and 50-ohm impedance. Cross-reference bandwidth and insertion loss parameters to ensure functional equivalence in the specific circuit design.
