DEA212495BT-7055A2

Overview

The DEA212495BT-7055A2 is a passive bandpass filter manufactured by TDK Corporation. It operates at a center frequency (Fc) of 2495 MHz with a bandwidth of 390,000 kHz. The device exhibits an insertion loss of 2.8 dB and utilizes a surface mount package type. Physical dimensions are specified as 2.00mm length by 1.50mm width, with a maximum height of 1.00mm. The component is housed in a 0805 (2012 Metric) case style featuring six PC pads.

Feature Summary

• Passive bandpass filter design for RF signal selection
• Surface mount construction for automated assembly
• Compact 0805 footprint suitable for space-constrained layouts

Applications

• RF front-end filtering in wireless communication modules
• Signal conditioning in cellular infrastructure equipment
• Frequency selection in IoT device transceivers

Procurement Notes

Verify the specific datasheet version to confirm moisture sensitivity levels and RoHS compliance status prior to procurement. Ensure that the ordering suffix matches the required tape and reel configuration for your manufacturing line. Cross-reference the manufacturer's official documentation to validate the exact electrical tolerances and physical pinout definitions against your schematic requirements.

Selection Notes

Select this component when a 2495 MHz center frequency with 390 MHz bandwidth is required. The 2.8 dB insertion loss must be acceptable for your link budget calculations. The 0805 package size dictates the available PCB real estate. Confirm that the surface mount technology aligns with your assembly capabilities and thermal management strategies for high-frequency passive components.
