DEA162450BT-1288A2

Overview

The TDK DEA162450BT-1288A2 is a surface-mount LTCC bandpass filter designed for EMI/RFI suppression and power line filtering applications. Operating at a center frequency of 2.45 GHz with a bandwidth of 100 MHz, this component provides effective signal conditioning in the ISM band. It features a compact 0603 (1.6x0.8mm) package suitable for space-constrained designs. The device supports operation within a temperature range of -40°C to +85°C and maintains a characteristic impedance of 50 ohms.

Feature Summary

• Provides EMI and RFI suppression capabilities for sensitive electronic circuits
• Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for stable RF performance
• Offers compact surface-mount packaging for automated assembly integration

Applications

• Automotive devices requiring interference mitigation
• Power line filtering in consumer electronics
• General EMI/RFI suppression modules

Procurement Notes

Verify current availability status as distribution channels may vary. Confirm RoHS compliance and environmental declarations against specific project requirements. Ensure the ordering suffix matches the required tape and reel configuration for manufacturing processes. Cross-reference datasheet revisions to guarantee compatibility with existing design specifications.

Selection Notes

Select this component when integrated EMI filtering is required alongside standard bandpass functionality in the 2.45 GHz range. The 0603 footprint allows for high-density PCB layouts where larger filters cannot fit. Consider thermal operating limits and insertion loss characteristics relative to system sensitivity thresholds during circuit design.

Part Context

This part belongs to the TDK DEA series of RF filters, which are engineered for wireless connectivity and automotive applications.
