PAT1220-C-6DB-T5

Overview

The PAT1220-C-6DB-T5 is a surface-mount RF attenuator manufactured by Susumu, designed for high-frequency applications up to 10 GHz. It provides a nominal attenuation of 6 dB with a characteristic impedance of 50 Ohms. The device operates within a frequency range of 0 Hz to 10 GHz and maintains a maximum Voltage Standing Wave Ratio (VSWR) of 1.3. It is housed in an 0805 (2012 Metric) package, suitable for SMD/SMT installation. The component supports an operating temperature range from -55°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides precise 6 dB signal attenuation for RF circuitry
• Operates effectively across a wide frequency spectrum up to 10 GHz
• Features low VSWR for improved signal integrity
• Designed for reliable performance in extreme temperature environments

Applications

• RF signal conditioning in wireless communication systems
• Impedance matching networks in microwave circuits
• Signal level adjustment in test and measurement equipment
• Attenuation stages in radar and satellite communication modules

Procurement Notes

Verify the specific suffix T5 corresponds to the required packaging format, such as cut tape or reel, when placing orders. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure the 6 dB tolerance meets the system requirements, as variations may exist between manufacturing batches. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a fixed 6 dB attenuation is required in a compact 0805 form factor. It is suitable for designs needing operation up to 10 GHz with strict VSWR limits. Consider the thermal rating of +125°C for high-temperature environments. Compare against other values in the PAT1220 series if different attenuation levels are needed while maintaining the same package and electrical characteristics.

Part Context

This part belongs to the Susumu PAT series of thin-film chip resistors configured as attenuators. The series offers various attenuation values in standard SMD packages. The PAT1220-C variant specifically targets RF applications requiring stable performance over wide bandwidths. It complements other passive components in high-frequency circuit design.

Replacement Considerations

Direct substitutes must match the 6 dB attenuation, 50 Ohm impedance, and 0805 package. Verify frequency response up to 10 GHz and VSWR specifications. Cross-reference with other manufacturers' RF attenuators offering identical electrical parameters and thermal ratings.
