DEA162450BT-1289A3

Overview

The TDK DEA162450BT-1289A3 is a surface-mount LTCC bandpass filter designed for RF applications. It operates at a center frequency of 2.45 GHz with a bandwidth of 100 MHz. The component features an insertion loss of 1.3 dB and maintains a 50-ohm impedance. It is housed in a compact 0603 (1608 metric) package with four terminals, measuring 1.60 mm in length, 0.80 mm in width, and 0.70 mm in maximum height. The device supports operating temperatures from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Utilizes Low-Temperature Co-fired Ceramic (LTCC) technology for stable RF performance
• Provides effective EMI/RFI suppression through bandpass filtering characteristics
• Designed for high-volume surface-mount assembly processes

Applications

• Wireless LAN modules requiring 2.4 GHz band filtering
• Bluetooth device signal conditioning
• ISM band communication equipment

Procurement Notes

Verify the specific suffix A3 against official TDK documentation to confirm exact electrical tolerances and termination specifications. Confirm current lifecycle status as distributors may list obsolete or end-of-life variants. Ensure compatibility with standard reflow soldering profiles for 0603 packages. Cross-reference datasheet revision dates to validate parameter accuracy before integration into new designs.

Selection Notes

Select this component when a compact 0603 footprint is required for 2.45 GHz filtering. The 100 MHz bandwidth suits narrowband ISM applications. Consider the 1.3 dB insertion loss impact on system link budget. Verify that the LTCC construction meets thermal management requirements for the target enclosure environment.

Part Context

This part belongs to the TDK DEA series of RF filters. The series utilizes multilayer ceramic technology to provide reliable filtering solutions for wireless communications. These components are engineered to replace discrete LC networks, saving board space while maintaining consistent performance across temperature variations.

Replacement Considerations

Abracon ADFC18-2450.00-A-T is listed as a substitute option. Verify mechanical dimensions and electrical parameters against the original datasheet before substitution.
