Overview
The TDK DEA202450BT-3201B2 is a multilayer bandpass RF filter designed for EMI/RFI suppression. It features a center frequency of 2.45GHz and a bandwidth of 100MHz. The insertion loss is specified at 2.5dB. The component utilizes a surface-mount 0805 (2012 Metric) package with a 6-pad configuration, measuring 2.00mm in length, 1.25mm in width, and 0.80mm in maximum height. It operates within a temperature range of -40°C to +85°C and supports a maximum power handling capacity of 1W.
Feature Summary
- Provides effective EMI and RFI suppression through bandpass filtering characteristics centered at 2.45GHz.
- Utilizes a compact 0805 surface-mount footprint to facilitate dense circuit board layouts.
- Maintains signal integrity with low insertion loss specifications within the passband.
Applications
- Wireless communication devices operating in the 2.4GHz ISM band
- Bluetooth module signal conditioning
- General electronic equipment requiring EMI/RFI suppression
Procurement Notes
Verify the specific suffix '3201B2' against official TDK documentation to ensure correct bandwidth and electrical parameters. Confirm RoHS3 compliance status and moisture sensitivity level requirements prior to integration. Ensure ordering quantities align with manufacturer standard packaging specifications to avoid supply discrepancies.
Selection Notes
Select this component when a 2.45GHz center frequency with 100MHz bandwidth is required for RF signal conditioning. The 0805 package size is suitable for applications with limited board space. Verify that the 1W power handling capability meets system requirements and that the 2.5dB insertion loss is acceptable for the link budget.
Part Context
This part belongs to the TDK DEA series of multilayer ceramic bandpass filters. These components are engineered for high-frequency applications, offering stable performance across industrial temperature ranges. The series provides various center frequencies and bandwidth options to suit different wireless standards and interference mitigation needs.
Replacement Considerations
Consult official TDK substitution guides for verified equivalents. Cross-referencing requires matching center frequency, bandwidth, insertion loss, and package dimensions. Generic substitutes may not guarantee identical RF performance or thermal stability.
