PAT1220-C-5DB-T5

Overview

The PAT1220-C-5DB-T5 is a fixed RF attenuator manufactured by Susumu, designed for surface-mount applications. It provides a nominal attenuation of 5 dB with a 50 Ohm impedance. The component operates within a frequency range of 0 Hz to 10 GHz and maintains a maximum VSWR of 1.3. It features a 0805 (2012 metric) package and supports SMD/SMT installation. The device is rated for a power handling capacity of 100 mW and functions reliably within an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides precise 5 dB signal attenuation in a compact 0805 surface-mount package
• Operates effectively across a wide frequency spectrum from DC to 10 GHz
• Maintains low voltage standing wave ratio for minimal signal reflection
• Complies with RoHS3 standards for environmental safety

Applications

• RF and microwave circuit signal conditioning
• Impedance matching networks in wireless communication systems
• Test and measurement equipment signal path management
• Mobile device internal RF front-end modules

Procurement Notes

Verify the complete part number including the suffix T5 to ensure correct packaging configuration. Confirm that the required attenuation value matches the specific design needs, as this model is fixed at 5 dB. Check datasheet specifications for thermal management requirements given the 100 mW power rating. Ensure compatibility with standard SMD/SMT assembly processes and reflow soldering profiles suitable for the 0805 package dimensions.

Selection Notes

Select this component when a fixed 5 dB attenuation is required in space-constrained designs utilizing the 0805 footprint. It is suitable for applications demanding stable performance up to 10 GHz with strict impedance control. Consider the 100 mW power limit when designing for high-power RF environments. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This component belongs to the PAT series of fixed attenuators from Susumu, which are engineered for high-reliability RF applications. The series offers various attenuation values while maintaining consistent electrical characteristics and physical dimensions. These attenuators are widely used in modern electronics where size reduction and signal integrity are critical priorities.

Replacement Considerations

TFA20C05DBER by Ohmite is a parameter-equivalent alternative offering similar 5 dB attenuation and 50 Ohm impedance specifications.
