PAT1220-C-4DB-T5

Overview

The PAT1220-C-4DB-T5 is a surface-mount RF attenuator manufactured by Susumu, designed for high-frequency signal processing applications. It provides a nominal attenuation of 4 dB within a 50 Ohm impedance system. The component operates across a frequency range from 0 Hz to 10 GHz with a maximum Voltage Standing Wave Ratio (VSWR) of 1.3. It is housed in an 0805 (2012 metric) package and supports SMD/SMT installation. The device functions reliably within an operating temperature range of -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides precise 4 dB signal attenuation in a compact 0805 surface-mount package
• Operates effectively from DC up to 10 GHz with low VSWR for minimal signal reflection
• Supports wide thermal operation from -55°C to +125°C for robust environmental stability

Applications

• RF signal level adjustment in wireless communication systems
• Impedance matching and signal conditioning in test and measurement equipment
• Attenuation stages in microwave circuit designs

Procurement Notes

Verify the specific part number PAT1220-C-4DB-T5 against official Susumu documentation to confirm availability and specifications. Ensure compatibility with 0805 footprint requirements and 50 Ohm system impedance. Check for RoHS compliance status and packaging options such as cut tape or reel. Confirm that the 10 GHz frequency limit and 125°C maximum operating temperature meet the design constraints.

Selection Notes

Select this component when a fixed 4 dB attenuation is required in a 50 Ohm environment up to 10 GHz. The 0805 package size offers space efficiency for dense PCB layouts. Consider the -55°C to +125°C temperature range for industrial or automotive applications. Compare with other PAT series variants if different attenuation values are needed while maintaining similar form factor and performance characteristics.

Part Context

This component belongs to the Susumu PAT series of chip attenuators, which are silicon-based resistive networks designed for RF and microwave applications. The series offers various attenuation values in standardized packages like 0805 and 1206. These devices are intended for use in circuits requiring precise signal reduction without significant distortion or reflection, supporting modern high-frequency electronic designs.
