DEA162500LT-5033F1

Overview

The DEA162500LT-5033F1 is a surface-mount low-pass RF filter manufactured by TDK Corporation. It operates within the 2400-2500 MHz frequency range with a center frequency of 2.45 GHz. The component utilizes a 0603 (1608 metric) package, measuring 1.60 mm in length and 0.80 mm in width. It features a nominal characteristic impedance of 50 Ω. Typical insertion loss in the passband is 0.21 dB, while typical return loss is 20.4 dB. The device provides significant attenuation for out-of-band signals, offering at least 25 dB rejection at 4800-5000 MHz and 18 dB at 7200-7500 MHz.

Feature Summary

• Provides signal conditioning for the 2400-2500 MHz band using a low-pass architecture.
• Delivers high attenuation against higher-frequency interference such as 4800-5000 MHz and 7200-7500 MHz signals.
• Designed for commercial grade applications with standard 50 Ω impedance compatibility.

Applications

• Wireless LAN (W-LAN) systems
• Bluetooth devices
• Wireless sensor networks
• Wireless test equipment

Procurement Notes

Verify the specific suffix F1 to ensure correct filtering characteristics. Confirm RoHS compliance status if required by assembly specifications. Check for obsolescence notices or alternative recommendations from TDK. Ensure ESD handling protocols are followed during surface mount placement. Validate footprint dimensions against PCB design libraries before procurement.

Selection Notes

Select this component for applications requiring compact size and precise filtering in the 2.4 GHz ISM band. The 0603 package suits space-constrained designs. Evaluate insertion loss requirements against the typical 0.21 dB specification. Consider return loss performance for impedance matching needs. Verify that the commercial grade rating meets environmental operating conditions.
