DEA102500LT-6307A1

Overview

The TDK DEA102500LT-6307A1 is a multilayer chip low-pass RF filter designed for wireless communication applications. It operates with a center frequency of 2.45 GHz and provides a bandwidth of 100 MHz. The component features an insertion loss of 0.33 dB and utilizes a 0402 (1005 metric) surface-mount package measuring 1.00 mm in length, 0.50 mm in width, and 0.40 mm in maximum height. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates low-pass filtering characteristics within a compact multilayer ceramic structure
• Optimized for high-frequency signal integrity with minimal insertion loss
• Supports automated surface-mount assembly processes

Applications

• Wireless LAN modules operating at 2.45 GHz
• Bluetooth device front-end circuits
• ISM band signal conditioning

Procurement Notes

Verify the specific suffix code to ensure correct electrical specifications, as variations exist within the DEA series. Confirm RoHS compliance status through official documentation before integration. Check for Not Recommended for New Design (NRND) status to assess long-term availability and lifecycle implications for production planning.

Selection Notes

Select this component when a 0402 footprint is required for 2.45 GHz low-pass filtering. Compare insertion loss and bandwidth against alternative DEA variants if stricter attenuation or different form factors are needed. Ensure the operating temperature range aligns with the target environment constraints.
