DEA202450BT-1294C1-H

Overview

The TDK DEA202450BT-1294C1-H is a multilayer band-pass filter designed for RF signal conditioning in wireless communication systems. It operates at a center frequency of 2.45 GHz with a bandwidth of 72 MHz and a characteristic impedance of 50 Ohms. The component features an insertion loss of 1.35 dB and is housed in a compact 0805 (2.0 x 1.25 mm) surface-mount package. It supports a minimum operating temperature of -40°C.

Feature Summary

• Multilayer ceramic construction for stable RF performance
• Optimized for 2.45 GHz ISM band applications
• Compact 0805 footprint for space-constrained designs

Applications

• WLAN modules

• Wireless sensor networks

Procurement Notes

Verify the specific suffix 'C1' against the required datasheet revision, as variations exist within the DEA series. Confirm RoHS compliance status directly from the manufacturer's current documentation. Ensure the 0805 package dimensions align with the PCB land pattern specifications before finalizing procurement orders.

Selection Notes

Select this component when a narrow 72 MHz bandwidth is required around the 2.45 GHz center frequency. The 50 Ohm impedance matches standard RF transmission lines. Consider the 1.35 dB insertion loss impact on system link budget. The -40°C minimum rating suits industrial or outdoor environments requiring wide thermal stability.
