TA0411A

Overview

The TST TA0411A is a Surface Acoustic Wave (SAW) bandpass filter designed for RF applications. It operates at a center frequency of 440 MHz with a bandwidth of 19 MHz and an insertion loss of 2.8 dB. The component utilizes an 8-SMD, no-lead package with dimensions of 5.0 x 5.0 mm. It supports a maximum input power level of 10 dBm and withstands a DC voltage of 3 V. The device functions within a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Provides high stability and low insertion loss for RF signal processing
• Utilizes a compact SMD surface-mount package for automated assembly
• Complies with RoHS environmental standards and lead-free packaging requirements

Applications

• High-frequency signal processing in wireless communication systems
• RF front-end filtering in mobile devices
• Base station receiver stages requiring specific band selection

Procurement Notes

Verify the manufacturer datasheet for exact electrical tolerances and thermal characteristics before integration. Confirm that the 8-SMD footprint matches the PCB land pattern design. Ensure supply chain sources provide original components to avoid counterfeit risks associated with RF filters. Check for any specific handling precautions regarding electrostatic discharge during storage and assembly processes.

Selection Notes

Select this component when a 440 MHz center frequency with 19 MHz bandwidth is required. Consider the 2.8 dB insertion loss impact on system noise figure. Evaluate the 5.0x5.0mm package size against available board space constraints. Verify compatibility with standard reflow soldering profiles due to lead-free construction. Assess thermal performance within the specified -40°C to +85°C operating range.
