CER0662A

Overview

The CER0662A is a surface-mount ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for the 2350 MHz frequency band, this component provides signal filtering with a specified insertion loss of 1 dB. It utilizes a monolithic package configuration suitable for automated assembly processes. The device is RoHS compliant and operates within standard industrial temperature ranges, ensuring reliability in wireless communication applications requiring precise frequency selection.

Feature Summary

• Monolithic ceramic construction for stable RF performance
• Surface-mount design optimized for high-volume PCB assembly
• Bandpass filtering capability centered at 2350 MHz

Applications

• Wireless local area network (WLAN) systems
• ISM band communication modules
• RF front-end filtering stages

Procurement Notes

Verify the specific datasheet revision when ordering, as manufacturing updates may occur. Confirm that the surface-mount footprint matches your PCB layout exactly. Ensure compatibility with reflow soldering profiles recommended for silver-coated barium ceramic components to maintain electrical integrity and mechanical stability during assembly.

Selection Notes

Select this component when a compact, low-loss solution is required for the 2350 MHz ISM band. Consider the monolithic package size constraints against available board space. Evaluate the 1 dB insertion loss specification against system link budget requirements. Verify that the bandwidth characteristics align with the specific channel spacing needs of the target application.

Part Context

This part belongs to the CER series of ceramic filters produced by Tusonix. These components are engineered for electromagnetic compatibility and signal integrity in modern electronic devices. The series offers various center frequencies and bandwidths tailored for different wireless standards, providing a reliable alternative to discrete LC filters in space-constrained designs.

Replacement Considerations

Consult official substitution guides from CTS Tusonix for direct equivalents. Cross-reference pinout and electrical specifications carefully if considering third-party alternatives. Ensure any substitute maintains the same surface-mount footprint and thermal characteristics to avoid redesign efforts.
