DEA142450BT-3028A1

Overview

The TDK DEA142450BT-3028A1 is a multilayer bandpass RF filter designed for the 2.4 GHz ISM band, specifically targeting W-LAN and Bluetooth applications. It operates within a passband of 2400 MHz to 2500 MHz with a characteristic impedance of 50 ohms. The component features a maximum insertion loss of 1.05 dB and supports an operating temperature range from -40°C to +85°C. Housed in a compact 5-SMD, no-lead package measuring 1.40 mm x 1.10 mm x 0.60 mm, it provides high attenuation for out-of-band signals to ensure signal integrity in wireless devices.

Feature Summary

• Optimized for 2.4 GHz W-LAN and Bluetooth frequency bands
• Compact surface-mount design suitable for space-constrained PCB layouts
• Low insertion loss ensures minimal signal degradation during transmission
• High out-of-band rejection capabilities for improved noise immunity

Applications

• Wireless Local Area Network (W-LAN) modules
• Bluetooth transceivers and headsets
• ISM band communication devices
• Mobile phone RF front ends

Procurement Notes

Verify the specific suffix A1 against the official TDK datasheet to confirm pinout and electrical tolerances. Ensure the procurement channel provides genuine components with traceable origin. Check for RoHS compliance documentation if required by local regulations. Confirm that the 5-SMD footprint matches the target PCB design constraints before finalizing orders.

Selection Notes

Select this component when a low-profile filter is required for 2.4 GHz applications. The 1.4x1.1mm size is ideal for miniaturized electronics. Compare insertion loss specifications against system budget requirements. Ensure the 50-ohm impedance matches the surrounding RF circuitry to prevent signal reflection and maintain optimal performance in wireless data transmission paths.

Part Context

This part belongs to TDK's DEA series of multilayer ceramic filters. These components are engineered for high reliability in consumer electronics. The DEA series utilizes advanced ceramic materials to achieve stable performance across varying temperatures. This specific model addresses the growing demand for compact RF solutions in portable wireless technology markets.

Replacement Considerations

DEA142450BT-3024A1 is a related variant within the same series. Verify dimensional compatibility and exact electrical parameters before substitution. Ensure the replacement maintains the same 5-SMD package and impedance characteristics to avoid redesigning the RF layout.
