Overview
The DEA162450BT-2180A1 is a multilayer band pass filter manufactured by TDK Corporation. It operates at a center frequency of 2.45 GHz with a bandwidth of 100 MHz. The component features a 50 Ohm impedance and utilizes surface mount technology in a 0603 (1608 metric) package measuring 1.6 mm x 0.8 mm x 0.7 mm. It supports an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.
Feature Summary
- Provides RF signal filtering within the 2.45 GHz ISM band
- Utilizes LTCC technology for compact surface mount integration
- Designed for stable performance across industrial temperature ranges
Applications
- Wireless LAN modules
- Bluetooth devices
- Zigbee transceivers
Procurement Notes
Verify the specific insertion loss value against the official datasheet, as values vary across the DEA series. Confirm the exact physical height dimension, as sources indicate potential discrepancies between 0.6 mm and 0.7 mm. Ensure compatibility with standard 0603 reflow soldering profiles. Check for end-of-life notices or alternative part recommendations from TDK.
Selection Notes
Select this component for applications requiring precise 2.45 GHz filtering in space-constrained designs. Compare insertion loss specifications against other DEA variants to meet specific signal integrity requirements. Verify that the 50 Ohm impedance matches the system design. Consider the operating temperature range for environmental suitability.
Part Context
This component belongs to the TDK DEA series of LTCC band pass filters. These filters are engineered for wireless connectivity applications. The series offers various insertion loss options within the same footprint. They are widely used in consumer electronics and IoT devices requiring reliable RF performance.
Replacement Considerations
Consult the TDK DEA series product map for direct substitutes. Other DEA162450BT variants with different suffixes may offer adjusted insertion loss characteristics while maintaining the same form factor.
