CER0347B

Overview

The CER0347B 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 filtering with a bandwidth of 100 MHz and an insertion loss of 1.7 dB. It utilizes a surface-mount monoblock package with two PCB pads, measuring 10.20 mm in length and 7.90 mm in width. The device is RoHS compliant and operates within standard commercial temperature ranges.

Feature Summary

• Provides bandpass filtering specifically tuned for the 2.45 GHz industrial, scientific, and medical frequency band
• Utilizes a compact monoblock surface-mount package designed for automated assembly processes
• Constructed using ceramic materials to ensure stable electrical performance and environmental durability

Applications

• Wireless local area network (WLAN) transceivers operating at 2.4 GHz
• Bluetooth communication modules requiring intermediate frequency filtering
• Industrial sensor systems utilizing 2.45 GHz radio frequency links

Procurement Notes

Verify the specific datasheet version for the CER0347B to confirm current manufacturing status and compliance certifications. Ensure that the ordering information matches the exact suffix requirements for tape and reel or cut tape packaging as specified by Tusonix. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select the CER0347B when a fixed center frequency of 2.45 GHz with a 100 MHz bandwidth is required. Consider the 1.7 dB insertion loss specification against system link budget requirements. Evaluate the physical dimensions of the monoblock package against available printed circuit board real estate constraints during the design phase.
