DEA202450BT-2114F1

Overview

The TDK DEA202450BT-2114F1 is a surface-mount multilayer bandpass RF filter designed for EMI/RFI suppression. It operates at a center frequency of 2.45GHz with a bandwidth of 100MHz. The component features an insertion loss of 2.5dB and utilizes a 0805 (2012 Metric) package measuring 2.00mm x 1.25mm x 0.50mm. It contains three printed circuit board pads. The device complies with RoHS3 standards and has a Moisture Sensitivity Level of 1.

Feature Summary

• Provides bandpass filtering characteristics centered at 2.45GHz to suppress electromagnetic interference.
• Utilizes a compact 0805 surface-mount ceramic construction for efficient PCB layout integration.
• Designed specifically for radio frequency applications requiring signal purity in the 2.45GHz range.

Applications

• Wireless communication systems operating in the 2.45GHz ISM band
• Bluetooth module interface circuits
• Wi-Fi transceiver front-end filtering
• General purpose EMI/RFI suppression in RF signal paths

Procurement Notes

Verify current availability status as this specific part number is listed as obsolete or end-of-life by the manufacturer. Confirm if alternative revisions or successor components within the DEA series are available for new designs. Ensure procurement sources provide authentic documentation matching the DEA202450BT-2114F1 designation to avoid counterfeit risks associated with discontinued electronic components.

Selection Notes

Select this component when a 2.45GHz bandpass filter with a 100MHz bandwidth is required in a 0805 footprint. Consider the 2.5dB insertion loss specification against system link budget requirements. Evaluate the 0.50mm maximum height constraint for low-profile assembly needs. Compare performance metrics with active alternatives if long-term supply stability is a critical design parameter.

Part Context

This component belongs to the TDK DEA series of multilayer ceramic RF filters. These devices are engineered for high-frequency signal conditioning in compact electronic assemblies. The DEA series typically offers various center frequencies and bandwidth options tailored for wireless connectivity standards, providing reliable attenuation of out-of-band noise while maintaining signal integrity in the passband.

Replacement Considerations

Public confirmed substitute part numbers include DEA202450BT-2175A1-H from TDK. Verify electrical compatibility regarding center frequency, bandwidth, and insertion loss before substitution. Check package dimensions and pin configuration to ensure mechanical fit on existing PCB layouts.
