Overview
The DEA162450BT-2139A1 is a surface-mount LTCC bandpass filter manufactured by TDK Corporation. It operates at a center frequency of 2.45 GHz with a bandwidth of 100 MHz, designed for RF applications in the 2.4 GHz ISM band. The component features a 50 Ohm impedance and utilizes a 0603 (1608 Metric) package size measuring 1.6 mm x 0.8 mm x 0.7 mm. It supports SMD/SMT termination types and functions within an operating temperature range of -40°C to +85°C.
Feature Summary
- Utilizes Low Temperature Co-fired Ceramic (LTCC) technology for stable RF performance
- Provides precise signal filtering within the 2.4 GHz industrial, scientific, and medical band
- Designed for compact surface-mount integration in wireless connectivity modules
Applications
- Wireless LAN (Wi-Fi) systems
- Bluetooth communication devices
- ISM band RF front-end modules
Procurement Notes
Verify the specific suffix against official TDK documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard reflow soldering profiles for 0603 packages. Confirm RoHS compliance status through current manufacturer declarations prior to procurement.
Selection Notes
Select this component for designs requiring a 2.45 GHz center frequency with a 100 MHz bandwidth. Ensure the PCB layout accommodates the 0603 footprint dimensions. Verify that the system impedance matches the 50 Ohm specification to minimize insertion loss and reflection.
Part Context
This part belongs to the TDK DEA series of multilayer chip bandpass filters. These components are engineered for high reliability in consumer electronics and wireless infrastructure. The DEA series typically offers low insertion loss and high selectivity for noise suppression in crowded RF environments.
Replacement Considerations
Consult TDK official substitution lists for verified alternatives. Generic equivalents may not match the LTCC construction or precise frequency response characteristics required for certified wireless standards.
