CER0485A

Overview

The CER0485A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for the 2.45 GHz ISM band, this component provides signal selection capabilities in RF applications. It features a compact surface-mount package with dimensions of 3.2mm x 1.6mm x 1.6mm. The filter exhibits an insertion loss of 1.5 dB and operates within a temperature range of -55°C to +125°C. It is RoHS compliant and suitable for high-frequency circuit integration.

Feature Summary

• Bandpass filtering optimized for the 2.45 GHz industrial, scientific, and medical frequency band
• Compact surface-mount design facilitating automated assembly and space-constrained layouts
• Wide operating temperature range supporting harsh environmental conditions

Applications

• Wireless local area network (WLAN) modules
• Bluetooth device interfaces
• Zigbee and other 2.4 GHz wireless sensor networks

Procurement Notes

Verify the specific datasheet version for the CER0485A to confirm exact electrical tolerances and pin configurations before finalizing designs. Ensure that the selected packaging option matches the production line requirements. Cross-reference the manufacturer's latest documentation to validate compliance with current environmental regulations such as RoHS3.

Selection Notes

Select the CER0485A when a dedicated ceramic solution is required for 2.45 GHz signal integrity. Consider its low profile and thermal stability compared to discrete LC components. Evaluate the insertion loss specifications against system link budget requirements. Confirm compatibility with standard reflow soldering profiles for surface-mount technology processes.

Part Context

This component belongs to the Tusonix family of ceramic filters, which are engineered for electromagnetic compatibility and signal conditioning. Tusonix, now part of CTS Electronic Components, specializes in passive components for RF and microwave applications. The CER series utilizes monolithic ceramic technology to provide stable performance in compact form factors.

Replacement Considerations

Consult official Tusonix/CTS substitution guides for verified equivalents. Generic replacements may not match the precise bandwidth or insertion loss characteristics required for 2.45 GHz compliance.
