PAT1632-C-4DB-T1

Overview

The PAT1632-C-4DB-T1 is a silicon chip attenuator manufactured by Susumu, designed for RF applications. It provides a fixed attenuation of 4dB with a nominal impedance of 50 ohms. The component operates within a frequency range from DC to 3GHz and handles a maximum power dissipation of 125mW. It utilizes a 1206 surface-mount package size. The device supports an operating temperature range from -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Fixed 4dB attenuation value for precise signal level control
• Silicon-based construction for reliable RF performance
• Wide operating temperature range suitable for harsh environments

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks requiring specific attenuation
• Test and measurement equipment signal paths

Procurement Notes

Verify the complete part number including the suffix T1 to ensure correct reel packaging configuration. Confirm that the 1206 footprint matches the target PCB layout dimensions. Check for RoHS compliance documentation if required by project specifications. Ensure the 125mW power rating is sufficient for the intended circuit application to prevent thermal issues during operation.

Selection Notes

Select this component when a fixed 4dB attenuation is required at 50 ohms within the 3GHz bandwidth. The 1206 package offers a balance between power handling and board space. Consider the silicon technology characteristics for stability. Compare against other PAT series variants if different attenuation values or power ratings are needed for the specific design constraints.

Part Context

This part belongs to the PAT series of chip attenuators from Susumu, which focuses on silicon-based solutions for RF circuits. The series includes various attenuation values and package sizes to support diverse wireless and microwave applications. The PAT1632-C-4DB-T1 specifically addresses needs for moderate power handling in compact designs.

Replacement Considerations

Direct substitutes may include other PAT series parts with identical 4dB attenuation and 1206 footprint, such as PAT1632-C-4DB-T1 variations if available. Cross-brand replacements require matching 50-ohm impedance, 4dB loss, and 1206 package dimensions while verifying frequency response up to 3GHz.
