LP1206A3800ASTR

Overview

The LP1206A3800ASTR is a thin-film low-pass RF filter manufactured by KYOCERA AVX. It operates at a cutoff frequency of 3.8 GHz with a nominal impedance of 50 Ohms. The device features an insertion loss of 0.8 dB and is housed in a 1206 (3216 Metric) surface-mount package measuring 3.08mm x 1.60mm x 0.97mm. It supports a temperature range from -40°C to +85°C, complies with RoHS3 standards, and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

• Thin-film multi-layer technology for high-frequency performance
• Steep roll-off characteristics with high out-of-band rejection
• Low insertion loss design for signal integrity
• Compact miniature case size suitable for space-constrained layouts

Applications

• Wireless communication systems
• RF front-end modules
• Base station equipment
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'ASTR' confirms the reel packaging format required for automated assembly processes. Confirm that the 3.8 GHz cutoff specification aligns precisely with the target application's spectral requirements. Ensure compatibility with standard reflow soldering profiles for 1206 surface-mount components during production integration.

Selection Notes

Select this component when a 3.8 GHz low-pass response is required within a 1206 footprint. Consider the 0.8 dB insertion loss and 50 Ohm impedance for system matching. Evaluate thermal stability across the -40°C to +85°C range against environmental conditions. Compare physical dimensions against board space constraints before finalizing the design.

Part Context

This part belongs to the LP series of RF filters from KYOCERA AVX. These components utilize proprietary thin-film technology to deliver consistent performance in miniature packages. The series is designed for applications demanding reliable signal conditioning in compact electronic devices.

Replacement Considerations

LP1206A3500ASTR: Lower cutoff frequency (3.5 GHz). LP1206A2700ANTR: Lower cutoff frequency (2.7 GHz). LP1206A0860ASTR: Significantly lower cutoff frequency (860 MHz). Verify electrical specifications match before substitution.
