CER0499A

Overview

The CER0499A is a surface-mount ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for the 2.14 GHz frequency band, this component utilizes a monoblock construction with two printed circuit board pads for installation. The device features silver-coated ceramic materials to ensure signal integrity in high-frequency applications. It is RoHS3 compliant and classified under ECCN EAR99, indicating it does not contain controlled strategic materials. The filter is intended for integration into compact electronic systems requiring precise frequency selection.

Feature Summary

• Surface-mount monoblock ceramic construction
• Silver-coated dielectric material
• RoHS3 compliant manufacturing

Applications

• Wireless communication modules operating at 2.14 GHz
• RF front-end filtering stages
• Compact electronic devices requiring surface-mount solutions

Procurement Notes

Verify the specific datasheet version from Tusonix or authorized distributors to confirm current electrical tolerances and pin configurations. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Check for any recent obsolescence notices as availability may vary across supply channels.

Selection Notes

Select this component when a fixed 2.14 GHz bandpass response is required in a surface-mount form factor. Consider the monoblock package size constraints and thermal management requirements during layout. Confirm that the insertion loss and bandwidth specifications meet the system's noise figure and selectivity targets.

Part Context

This part belongs to the Tusonix CER series of ceramic filters, which are known for their stability and compact size. The series supports various frequency bands for RF applications. The CER0499A specifically targets the 2.14 GHz range, distinguishing it from other models in the lineup that may operate at different center frequencies or bandwidths.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Cross-referencing requires matching the 2.14 GHz center frequency, bandwidth, and SMD package dimensions with alternative manufacturers' offerings.
