DEA200710LT-1238A1

Overview

The DEA200710LT-1238A1 is a multilayer low-pass filter manufactured by TDK Corporation using LTCC technology. Designed for radio frequency signal conditioning, this component operates within the 470–710 MHz range with a center frequency of 590 MHz and a bandwidth of 240 MHz. It features an insertion loss of 0.88 dB and is housed in a compact 0805 (2012 Metric) surface-mount package with six PC pads. The device is engineered to provide effective attenuation of high-frequency noise while maintaining signal integrity in RF applications.

Feature Summary

• Utilizes LTCC construction for stable RF performance
• Provides low-pass filtering for signal conditioning
• Compact 0805 surface-mount footprint

Applications

• RF signal conditioning circuits
• Noise suppression in communication modules
• High-frequency interference filtering

Procurement Notes

Verify the specific LTCC low-pass filter designation against official TDK documentation to ensure compatibility with target RF frequencies. Confirm that the 0805 package dimensions and pad layout match the PCB design requirements. Cross-reference the center frequency and bandwidth specifications with system needs to validate performance suitability before procurement.

Selection Notes

Select this component when a compact, multilayer solution is required for attenuating frequencies above the passband in RF systems. The LTCC technology offers reliability in demanding environments. Ensure the operating frequency aligns with the specified 590 MHz center point and that the 0.88 dB insertion loss meets system budget constraints.

Part Context

This part belongs to TDK's family of LTCC-based RF filters designed for signal conditioning. These components are characterized by their ability to handle radio frequency signals with minimal distortion. The DEA series typically integrates passive filtering elements into a robust ceramic structure suitable for modern electronic assemblies requiring small form factors.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Do not assume generic RF filters are compatible due to potential differences in impedance, bandwidth, or package geometry.
