DEA161910LT-9031A1

Overview

The DEA161910LT-9031A1 is a multilayer low-pass filter designed for signal conditioning in wireless communication systems. It operates as a dual-channel (2-in-1) component covering the DCS/PCS frequency bands of 824–915MHz and 1710–1910MHz. The device utilizes a compact EIA 0603 package with dimensions of 1.6x0.8mm. Key electrical characteristics include a center frequency of 869.5MHz for the lower band and 1.81GHz for the upper band, with a specified insertion loss of 0.6dB. The maximum height is 0.70mm.

Feature Summary

• Dual-band low-pass filtering capability for simultaneous DCS and PCS band support
• Compact 1.6x0.8mm surface-mount footprint suitable for space-constrained designs
• Multilayer ceramic construction for reliable RF signal conditioning

Applications

• DCS/PCS cellular phone front-end modules
• Wireless LAN devices operating in relevant frequency ranges
• Bluetooth-enabled mobile terminals
• General telecommunications equipment requiring RF interference suppression

Procurement Notes

Verify current manufacturing status before procurement as multiple sources indicate this part may be obsolete or discontinued. Confirm availability through authorized TDK distributors or secondary market suppliers if active stock is required. Ensure replacement components meet identical electrical specifications and physical dimensions to maintain circuit integrity without redesign.

Selection Notes

Select this component when designing circuits requiring integrated filtering for both 800MHz and 1.8GHz cellular bands within a single 0603 footprint. Consider the 0.6dB insertion loss specification for signal path efficiency requirements. Evaluate mechanical constraints against the 0.70mm maximum height limit. Verify compatibility with standard SMT assembly processes for small outline packages.

Part Context

This component belongs to TDK's multilayer low-pass filter series intended for wireless connectivity applications. It addresses the demand for miniaturized signal conditioning in mobile devices supporting multiple cellular standards. The 2-in-1 design consolidates filtering functions typically requiring separate discrete components, aiding in board space optimization for smartphones and tablets.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. As the part is indicated as stopped production or obsolete, engineers must identify equivalent components by matching the 824-915MHz and 1710-1910MHz frequency ranges, 0603 package size, and low-pass filter topology.
