DEA205375BT-2054A1

Overview

The TDK DEA205375BT-2054A1 is a surface-mount RF bandpass filter designed for high-frequency wireless applications. It features a center frequency of 5.375GHz with a bandwidth of 950MHz. The component exhibits an insertion loss of 2.2dB and a ripple of 0.6dB. It is housed in a compact 0805 (2012 Metric) package, measuring 2.00mm x 1.25mm x 1.05mm maximum height. The device supports RoHS3 compliance and operates within a standard commercial temperature range.

Feature Summary

• Provides selective signal filtering at 5.375GHz to suppress out-of-band interference
• Utilizes a compact 0805 surface-mount footprint for dense PCB layouts
• Ensures low signal attenuation with specified insertion loss characteristics

Applications

• Wireless communication systems requiring 5.375GHz band support
• RF front-end modules for base stations or access points
• Signal conditioning in microwave frequency circuits

Procurement Notes

Verify the specific ordering suffix and packaging configuration against the manufacturer's latest datasheet before procurement. Confirm that the component status remains suitable for new designs, as availability may vary by region. Ensure compatibility with standard reflow soldering profiles for 0805 packages. Cross-reference the EDA model for accurate placement data during layout design.

Selection Notes

Select this component when a precise 5.375GHz center frequency is required with minimal insertion loss. The 0805 package size offers a balance between performance and board space efficiency. Consider the 950MHz bandwidth relative to adjacent channel requirements. Verify thermal stability needs against the specified operating temperature range for the target environment.

Part Context

This part belongs to TDK's DEA series of RF filters, which are engineered for cellular and wireless connectivity applications. The series focuses on providing reliable signal integrity in compact form factors suitable for modern mobile infrastructure and consumer electronics. The DEA205375BT-2054A1 specifically targets higher frequency bands within this portfolio.

Replacement Considerations

TDK recommends DEA165550BT-2230C2-H as a substitute. Verify electrical parameter compatibility, particularly center frequency and bandwidth differences, before substitution. Ensure mechanical footprint alignment if direct pin-to-pin replacement is required.
