CER0454B

Overview

The CER0454B is a ceramic band-pass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for the 2.4 GHz to 2.5 GHz frequency range, this component operates at a center frequency of 2.45 GHz. It utilizes surface-mount device (SMD/SMT) termination styles for integration into printed circuit boards. The physical package dimensions are specified as 10.2 mm in length, 4.1 mm in width, and 4 mm in height. This passive component belongs to the Ceramic Filters subcategory within the broader Filters product line.

Feature Summary

• Provides band-pass filtering characteristics specifically tuned for the 2.4 GHz to 2.5 GHz industrial, scientific, and medical (ISM) radio bands.
• Utilizes ceramic dielectric materials to achieve stable frequency response and low insertion loss in compact form factors.
• Supports surface-mount technology (SMD/SMT) assembly processes for automated manufacturing and high-density board layouts.

Applications

• Wireless local area network (WLAN) systems operating in the 2.4 GHz ISM band.
• Bluetooth wireless communication modules requiring signal isolation.
• Zigbee and other IEEE 802.15.4 based personal area network devices.

Procurement Notes

Verify the manufacturer designation as Tusonix, a subsidiary of CTS Electronic Components, to ensure authenticity. Confirm that the part meets RoHS compliance requirements if mandated by your regional regulations. Check the specific package dimensions of 10.2 mm x 4.1 mm x 4 mm against your PCB footprint design. Ensure the SMD/SMT termination style matches your assembly capabilities. Validate the active lifecycle status before long-term production planning.

Selection Notes

Select the CER0454B when designing circuits for the 2.4 GHz to 2.5 GHz spectrum requiring precise band-pass filtering. Consider its 10.2 mm x 4.1 mm x 4 mm package size for space-constrained applications. Evaluate its suitability for SMD/SMT assembly lines. Compare its performance against other ceramic filters in the same frequency range. Ensure compatibility with the target RF front-end architecture.
