CER0004A

Overview

The CER0004A is a bandpass ceramic filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates within the frequency range of 1.2176 GHz to 1.2376 GHz with a center frequency of 1.2276 GHz. The device features a bandwidth of 20 MHz and utilizes a monoblock construction with silver-coated ceramic material. Designed for surface mount installation, it employs a two-pad configuration housed in a package measuring 11.75 mm x 9.92 mm x 4.5 mm. The component complies with RoHS standards and is supplied in tape and reel packaging.

Feature Summary

• Utilizes a monoblock ceramic structure coated with silver for signal filtering
• Designed for surface mount technology with a two-pad terminal configuration
• Operates as a bandpass filter within the specified microwave frequency range

Applications

• Microwave communication systems requiring specific bandpass filtering
• Electronic circuits operating near 1.2276 GHz center frequency
• Surface mount assembly processes for passive component integration

Procurement Notes

Verify that the required specifications match the 1.2176 GHz to 1.2376 GHz operational range and the 20 MHz bandwidth. Confirm the physical dimensions of 11.75 mm x 9.92 mm x 4.5 mm fit the design constraints. Ensure the manufacturer is identified as Tusonix, a subsidiary of CTS Electronic Components, and check for RoHS compliance status if environmental regulations apply to the final product assembly.

Selection Notes

Select this component when a fixed center frequency of 1.2276 GHz with a narrow 20 MHz bandwidth is required. The monoblock ceramic construction offers stability for surface mount applications. Consider the specific package size of 11.75 mm x 9.92 mm for board layout compatibility. Verify that the silver coating on the ceramic block meets the electrical and environmental requirements of the target circuit design.
