DEA102450BT-1278A2

Overview

The TDK DEA102450BT-1278A2 is a multilayer band pass filter designed for the 2.4 GHz ISM band, specifically covering 2400–2500 MHz. It features a compact 0402 (1.0x0.5mm) surface-mount package with four terminals. Key electrical parameters include a typical insertion loss of 2.36 dB and a maximum of 3.0 dB within the passband. The device exhibits a typical return loss of 22 dB and minimum attenuation of 20 dB in the 824–960 MHz range. It complies with RoHS directives and operates as a commercial-grade component.

Feature Summary

Compact 0402 surface-mount footprint suitable for space-constrained designs
Optimized signal filtering for the 2.4 GHz ISM band
Low insertion loss to maintain signal integrity
High attenuation characteristics against out-of-band interference

Applications

Wireless Local Area Network (WLAN) systems
Bluetooth devices
2.4 GHz wireless communication equipment

Procurement Notes

Verify the specific suffix '1278A2' to ensure correct tape-and-reel configuration and binning. Confirm RoHS compliance status matches current regulatory requirements. Check moisture sensitivity level handling procedures during assembly. Validate pinout definitions against the official datasheet to prevent circuit errors.

Selection Notes

Select this component when a small form factor is required for 2.4 GHz filtering. Ensure the design accommodates the 0402 package dimensions and recommended pad layout. Consider the insertion loss specifications relative to system link budget requirements. Verify compatibility with standard surface-mount reflow soldering processes.

Part Context

This part belongs to the TDK DEA series of multilayer ceramic filters. These components utilize advanced manufacturing techniques to provide high performance in miniature packages. The series is widely used in RF front-end modules for consumer electronics requiring reliable frequency selection.
