Overview
The TDK DEA202450BT-7152A1 is a surface-mount bandpass RF filter designed for the 2.4 GHz ISM band. It operates with a center frequency of 2.45 GHz and supports a bandwidth ranging from 2400 MHz to 2500 MHz. The component utilizes LTCC technology within an 0805 (2012 Metric) package featuring four terminals. Physical dimensions are specified as 2.00 mm in length, 1.25 mm in width, and a maximum height of 1.05 mm. It complies with RoHS3 standards and carries an MSL rating of Level 1.
Feature Summary
- Utilizes Low Temperature Co-fired Ceramic (LTCC) construction for stable RF performance
- Provides bandpass filtering characteristics optimized for the 2.4 GHz industrial, scientific, and medical band
- Designed for surface-mount assembly using standard 0805 footprint dimensions
Applications
- Wireless local area network (WLAN) transceivers
- Bluetooth low energy communication modules
- ZigBee and other 2.4 GHz wireless sensor networks
Procurement Notes
Verify the specific suffix '7152A1' against official TDK documentation to confirm the exact bandwidth and insertion loss specifications. Ensure the procurement channel provides valid traceability for RoHS3 compliance. Confirm that the 0805 package variant matches the design requirements for the target PCB layout and thermal management strategy.
Selection Notes
Select this component when a narrow bandpass response centered at 2.45 GHz is required for interference rejection. Compare the 2400-2500 MHz bandwidth against alternative models like the 7210A1 if wider passband tolerance is needed. Evaluate the 1.05 mm maximum height constraint against available vertical clearance in the final assembly stack-up.
Part Context
This part belongs to the TDK DEA series of RF filters, which offers various bandpass configurations across different frequencies. The DEA202450BT-7152A1 specifically targets the 2.4 GHz spectrum, distinguishing itself from other series members by its defined 2400-2500 MHz operational window and four-terminal 0805 form factor.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Designers should consult TDK's official cross-reference guides or datasheets for potential alternatives with matching electrical and mechanical parameters.
