PAT0510S-C-8DB-T10

Overview

The PAT0510S-C-8DB-T10 is a high precision chip attenuator manufactured by Susumu, designed for RF and microwave applications. It provides a nominal attenuation of 8 dB with a tolerance of 0.7 dB across a frequency range from 0 Hz to 10 GHz. The component features a characteristic impedance of 50 Ohms and maintains a maximum VSWR of 1.3. It operates within a temperature range of -55°C to +125°C and has a power rating of 32 mW (15.05 dBm). Packaged in a compact 0402 surface-mount footprint, it utilizes silicon technology.

Feature Summary

• High precision fixed attenuation performance with tight tolerance
• Wideband operation covering DC to 10 GHz frequencies
• Compact 0402 surface-mount package design
• Robust thermal stability across extended industrial temperature ranges

Applications

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

Procurement Notes

Verify the specific suffix T10 against official Susumu documentation to confirm reel specifications and tape dimensions. Ensure that the 0402 package dimensions align with your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest environmental declarations. Cross-reference the 8 dB attenuation value with system simulation models to ensure accuracy within the 0.7 dB tolerance band.

Selection Notes

Select this component when precise DC-to-10 GHz attenuation is required in space-constrained designs. The 0402 package suits high-density PCB layouts. Consider the 32 mW power rating for low-power signal paths. Verify that the 50 Ohm impedance matches the system architecture. Evaluate the -55°C to +125°C operating range against environmental conditions.

Part Context

This part belongs to the Susumu PAT series of thin-film chip attenuators. These components are engineered for high reliability in RF applications. The PAT0510S-C variant specifically denotes the 0402 package size and silicon construction. The series offers various attenuation values to support diverse circuit requirements while maintaining consistent electrical characteristics.

Replacement Considerations

Direct substitutes include other PAT0510S-C variants with different attenuation values, such as PAT0510S-C-5DB-T10 or PAT0510S-C-10DB-T10, provided the attenuation requirement differs. Generic 0402 attenuators may match physical dimensions but likely lack the specified 0.7 dB tolerance and 10 GHz performance.
