PAT0510S-C-4DB-T10

Overview

The Susumu PAT0510S-C-4DB-T10 is a high-precision chip attenuator designed for RF and IF applications. It provides a fixed attenuation of 4 dB with a nominal impedance of 50 Ohms. The component operates within a frequency range of 0 Hz to 10 GHz, maintaining a maximum VSWR of 1.3. It features a compact 0402 (1005 Metric) surface-mount package and supports a maximum power dissipation of 32 mW. The device functions reliably across an operating temperature range from -55°C to +125°C.

Feature Summary

• High precision fixed attenuation suitable for signal level control
• Compact 0402 surface-mount footprint for space-constrained designs
• Wide operational frequency range extending up to 10 GHz
• Extended temperature stability for harsh environment reliability

Applications

• RF signal conditioning in wireless communication systems
• IF stage attenuation in receiver front-ends
• Test and measurement equipment calibration
• RFID tag and reader circuitry

Procurement Notes

Verify the complete part number including the suffix T10 to confirm reel packaging specifications. Ensure the procurement order matches the required 4 dB attenuation value and 50 Ohm impedance. Confirm RoHS compliance status if restricted substances are mandated by project requirements. Cross-reference the manufacturer's datasheet for specific handling and soldering guidelines prior to assembly.

Selection Notes

Select this component when a precise 4 dB reduction is required in a 50 Ohm system. The 0402 package size is optimal for dense PCB layouts where standard resistor footprints are insufficient. Consider the 32 mW power rating against expected signal levels to prevent thermal issues. The wide temperature range supports operation in automotive or industrial environments without derating concerns.

Part Context

This part belongs to the Susumu PAT series of thin-film chip attenuators. These components are engineered for high accuracy and stability in radio frequency circuits. The series offers various attenuation values in a standardized small outline package, allowing designers to maintain consistent board layouts while adjusting signal strength requirements across different product variants.

Replacement Considerations

Direct substitutes include other Susumu parts in the same series with different attenuation values, such as PAT0510S-C-1DB-T10 or PAT0510S-C-2DB-T10, provided the specific dB loss differs. Generic replacements must match the 0402 package, 50 Ohm impedance, and 10 GHz frequency capability to ensure electrical compatibility.
