DEA251002LT-5048A1

Overview

The DEA251002LT-5048A1 is a multilayer low-pass filter from TDK Corporation's DEA series, designed for RF signal conditioning. It features a 1008 (2520 Metric) surface-mount package with dimensions of 2.50mm length, 2.00mm width, and a maximum thickness of 1.00mm. The component operates within a temperature range of -40°C to 105°C and maintains a nominal impedance of 75 Ohms. Its passband frequency spans from 5 MHz to 1002 MHz, providing an insertion loss of 2.4 dB at the specified cutoff frequency.

Feature Summary

• Multilayer ceramic construction for compact RF filtering applications
• Designed for general electronic equipment including audio-visual systems
• Surface-mount compatibility with standard 1008 footprint

Applications

• Set-top boxes (STB)
• Audio-visual equipment
• General electronic equipment requiring signal conditioning

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with TDK or authorized distributors before procurement. Confirm that the 1008 package dimensions and 75 Ohm impedance match your circuit design requirements. Ensure operating temperature ranges align with your environmental specifications. Check for any specific handling instructions regarding the multilayer ceramic structure.

Selection Notes

Select this component when a 75 Ohm impedance low-pass filter is required for frequencies up to 1.002 GHz in space-constrained designs. The 1008 package size offers a balance between performance and board area. Consider the -40°C to 105°C operating range for industrial or consumer applications. Verify insertion loss characteristics against system noise budget requirements.

Part Context

This part belongs to TDK's DEA series of multilayer low-pass filters, which are engineered for high-frequency signal integrity in consumer electronics. The series typically targets applications where compact size and reliable attenuation of higher frequencies are critical. These components are widely used in digital video and audio transmission lines to suppress unwanted harmonic content.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult TDK technical support for direct equivalents within the DEA series or alternative manufacturers offering 75 Ohm, 1008 package low-pass filters with similar cutoff frequencies.
