PAT1632-C-0DB-T1

Overview

The PAT1632-C-0DB-T1 is a silicon-based chip attenuator from the Susumu PAT series, designed for RF and wireless applications. It features a 0dB attenuation value with a nominal impedance of 50 ohms. The component supports a frequency range from DC to 3GHz and has a maximum power rating of 125mW. Housed in a compact 1206 (3216 metric) surface-mount package, it operates within a temperature range of -55°C to +125°C. The device utilizes standard terminal designs similar to chip resistors, facilitating easy integration into PCB layouts while supporting equipment miniaturization.

Feature Summary

• Utilizes silicon technology for stable RF signal attenuation
• Standard 1206 surface-mount footprint for simplified PCB assembly
• Wide operating temperature range suitable for harsh environments

Applications

• RF signal conditioning in wireless communication modules
• Impedance matching networks in 50-ohm systems
• Signal level adjustment in test and measurement equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required packaging formats such as cut tape or reel quantities. Confirm RoHS compliance status and environmental declarations prior to finalizing procurement orders, as regulatory documentation may vary by production batch and region.

Selection Notes

Select this component when a zero-decibel insertion loss is required for impedance bridging or layout compensation rather than signal reduction. Ensure the design accommodates the 125mW power dissipation limit at the expected operating temperature. Verify that the 3GHz bandwidth meets the highest frequency requirements of the target application circuit.

Part Context

This part belongs to the Susumu PAT series of precision chip attenuators. The series offers various attenuation values and power ratings across multiple package sizes, including 0603, 1206, and larger form factors. These components are engineered to provide consistent performance in high-frequency circuits where precise signal control is critical for system integrity.

Replacement Considerations

Direct substitutes include other Susumu PAT series parts with identical 1206 packaging and 50-ohm impedance specifications, such as the PAT1632-C-1DB-T1 for different attenuation needs. Cross-manufacturer replacements require matching the 1206 footprint, 50-ohm impedance, and DC-3GHz frequency response characteristics.
