CER0787B

Overview

The CER0787B is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for surface-mount installation, this component operates within the 2.45 GHz ISM band with a center frequency of 2.45 GHz and a bandwidth of 100 MHz. It features a monoblock package with a 3-pad configuration and a maximum height of 0.177 inches (4.50 mm). The device exhibits an insertion loss of 1 dB and is compliant with RoHS3 standards.

Feature Summary

• Utilizes ceramic technology for stable RF filtering performance in the 2.45 GHz ISM band
• Surface-mount monoblock construction designed for automated PCB assembly processes
• Provides defined 100 MHz bandwidth characteristics for signal selection

Applications

• Wireless local area network (WLAN) systems operating at 2.45 GHz
• Bluetooth communication modules requiring ISM band filtering
• Industrial, Scientific, and Medical (ISM) equipment utilizing 2.45 GHz frequencies

Procurement Notes

Verify the specific datasheet version for the CER0787B to confirm current RoHS3 compliance status and exact mechanical dimensions prior to integration. Ensure that the 3-pad footprint matches the target PCB layout design. Confirm that the 1 dB insertion loss specification aligns with system link budget requirements. Check for any specific handling instructions related to the ceramic material properties during assembly.

Selection Notes

Select the CER0787B when a compact, surface-mount solution is required for 2.45 GHz applications. The monoblock package offers space efficiency compared to through-hole alternatives. Consider the 100 MHz bandwidth relative to the modulation scheme used in the application. Verify compatibility with standard reflow soldering profiles for ceramic components to ensure reliable joint formation without thermal shock damage.
