PAT1220-C-2DB-T5

Overview

The Susumu PAT1220-C-2DB-T5 is a surface-mount RF attenuator designed for high-precision signal control. It provides a nominal attenuation of 2 dB with a 50 Ohm impedance, operating across a frequency range from 0 Hz to 10 GHz. The component features a maximum VSWR of 1.3 and handles up to 100 mW of power. Housed in an 0805 (2012 metric) package, it supports SMD/SMT installation and functions within a temperature range of -55°C to +125°C.

Feature Summary

• Provides precise 2 dB attenuation for RF signal management
• Operates effectively from DC to 10 GHz frequencies
• Maintains low voltage standing wave ratio for signal integrity
• Supports standard surface mount assembly processes

Applications

• RF circuit signal level adjustment
• Impedance matching networks
• Test and measurement equipment
• Wireless communication systems

Procurement Notes

Verify the specific suffix T5 corresponds to the required packaging format, such as cut tape or reel, against official distributor listings. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the 0805 footprint matches the design board layout. Cross-reference the manufacturer part number with authorized supply channels to guarantee authenticity and traceability.

Selection Notes

Select this component when a fixed 2 dB reduction is required in a 50 Ohm system. Consider the 0805 package size for space-constrained designs. Evaluate the 100 mW power rating against expected signal levels. Check the 10 GHz frequency limit to ensure suitability for the target application bandwidth. Compare thermal performance if operating near the upper temperature limits.

Part Context

This part belongs to the Susumu PAT series of thin-film chip attenuators. The series offers various attenuation values in standardized packages. The PAT1220-C variant specifically denotes the 0805 form factor. These components are engineered for consistent performance in radio frequency applications requiring stable attenuation characteristics over wide bandwidths.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative manufacturers by matching impedance, attenuation value, frequency range, and package dimensions before substitution.
