DEA202450BT-7112E1

Overview

The DEA202450BT-7112E1 is a signal conditioning component manufactured by TDK Corporation, classified as an RF filter within the DEA series. It functions as a low-pass filter with a center frequency of 2.45 GHz. The device utilizes surface-mount technology (SMD/SMT) for board mounting and operates within a temperature range of -40°C to +85°C. The component is housed in a compact 0805 (2012 metric) package, measuring 2.00mm x 1.25mm. This part is currently obsolete and has been discontinued by the manufacturer.

Feature Summary

Provides low-pass filtering characteristics for RF signal conditioning applications.
Designed for operation at a 2.45 GHz center frequency.
Constructed using LTCC technology for high reliability.

Applications

RF signal path filtering in wireless communication modules.
Harmonic suppression in 2.4 GHz ISM band transceivers.
Signal integrity management in compact electronic devices.

Procurement Notes

This component is officially marked as obsolete and end-of-life by TDK Corporation. Procurement is restricted to remaining distributor inventory or secondary markets. Verify authenticity carefully due to potential surplus stock variations. Confirm final availability and condition directly with authorized distributors before integration into new designs, as supply continuity cannot be guaranteed.

Selection Notes

Engineers should prioritize active alternatives from the same DEA series or compatible families due to the obsolete status of this specific part number. Evaluate replacement components for identical footprint dimensions, electrical specifications, and thermal performance. Ensure that any substitute maintains compatibility with existing PCB layouts and regulatory certifications without requiring design modifications.

Part Context

The DEA series represents TDK's line of multilayer ceramic filters utilizing Low-Temperature Co-fired Ceramic (LTCC) technology. These components are engineered for high-performance RF applications requiring precise frequency control and miniaturization. The DEA202450BT-7112E1 specifically addresses low-pass filtering needs within this portfolio, serving niche requirements in the 2.45 GHz spectrum before its discontinuation.
