CER0342A

Overview

The CER0342A 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 an insertion loss of 1 dB and utilizes a monolithic package configuration with two printed circuit board pads. The device is currently active in production and complies with RoHS3 standards.

Feature Summary

• Provides selective signal transmission within the 2.45 GHz industrial, scientific, and medical frequency band
• Utilizes monolithic ceramic construction for compact surface-mount integration
• Ensures signal integrity through low insertion loss characteristics

Applications

• Wireless local area network (WLAN) systems operating at 2.4 GHz
• Bluetooth communication modules
• Zigbee and other IEEE 802.15.4 based wireless sensor networks

Procurement Notes

Verify the specific datasheet version to confirm exact electrical tolerances and thermal specifications before finalizing the design. Ensure that the surface-mount footprint matches the mechanical dimensions provided in the official manufacturer documentation. Confirm compliance requirements such as RoHS3 status align with target market regulations. Cross-reference the manufacturer part number with distributor listings to ensure authenticity and correct revision levels.

Selection Notes

Select this component when a compact, low-loss solution is required for filtering noise in the 2.45 GHz spectrum. The monolithic surface-mount package facilitates automated assembly and reduces board space compared to larger ceramic resonators. Consider the 100 MHz bandwidth relative to the modulation scheme of the intended wireless protocol to ensure adequate signal pass-through without excessive attenuation.

Part Context

This component belongs to the family of passive ceramic filters produced by Tusonix under the CTS Electronic Components umbrella. These filters are engineered for high-reliability applications requiring stable frequency response in harsh environments. The product line emphasizes miniaturization and performance consistency for modern wireless communication infrastructure.

Replacement Considerations

Consult official Tusonix or CTS documentation for verified equivalent part numbers. Do not substitute with generic components unless electrical parameters including center frequency, bandwidth, and insertion loss are explicitly matched in the manufacturer's cross-reference guide.
