DEA212450BT-7043C1

Overview

The DEA212450BT-7043C1 is a band-pass RF filter manufactured by TDK Corporation, designed for EMI and RFI suppression applications. It utilizes low-temperature co-fired ceramic (LTCC) technology to achieve low insertion loss and low latency performance. The component operates within a frequency range of 729MHz to 2690MHz, centered around 2.45GHz. It is housed in an 0805 surface-mount package with physical dimensions of 2.00mm length, 1.50mm width, and a maximum thickness of 1.00mm. The device supports an operating temperature range from -30°C to 85°C.

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with TDK Corporation or authorized distributors before procurement. Confirm that the LTCC construction and 0805 footprint match your PCB design requirements. Ensure the operating temperature range of -30°C to 85°C meets your environmental specifications. Cross-reference the 729MHz to 2690MHz frequency range with your system's signal integrity needs to prevent performance degradation.

Selection Notes

Select this component when low insertion loss and minimal latency are critical for signals between 729MHz and 2690MHz. The 0805 package size suits space-constrained designs requiring robust EMI suppression. Consider the LTCC material properties for thermal stability within the specified -30°C to 85°C range. Evaluate the center frequency alignment with your 2.45GHz application requirements to ensure optimal filtering performance without excessive signal attenuation.

Part Context

This part belongs to TDK's series of LTCC-based RF filters, which leverage ceramic manufacturing techniques for compact, high-performance passive components. These filters are engineered for modern electronic systems demanding efficient electromagnetic interference management. The 0805 form factor aligns with standard surface-mount assembly processes, facilitating integration into various consumer and industrial electronics platforms requiring reliable signal purity.

Replacement Considerations

Consult official TDK documentation for verified substitute part numbers. Do not assume cross-compatibility with generic RF filters due to specific LTCC characteristics and precise frequency response requirements.
