PAT1220-C-10DB-T5

Overview

The PAT1220-C-10DB-T5 is a surface-mount RF attenuator manufactured by Susumu. It provides a nominal attenuation of 10 dB with a 50 Ohm impedance. The device 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 suitable for SMD/SMT installation. The component supports a power rating of 100 mW and functions within an operating temperature range of -55°C to +125°C.

Feature Summary

• Provides precise 10 dB signal attenuation in a compact 0805 surface-mount package
• Operates across a wide frequency spectrum from DC to 10 GHz
• Maintains low voltage standing wave ratio for effective signal integrity
• Designed for high-temperature environments up to 125°C

Applications

• RF signal conditioning in wireless communication systems
• Test and measurement equipment requiring fixed attenuation
• Microwave circuit design for signal level adjustment
• Mobile device RF front-end modules

Procurement Notes

Verify the specific suffix T5 against the manufacturer datasheet to confirm packaging configuration, as ordering suffixes may indicate variations in reel or cut tape specifications. Ensure the required attenuation value matches the 10 dB designation. Confirm RoHS compliance status directly through official documentation before finalizing procurement orders.

Selection Notes

Select this component when a fixed 10 dB attenuation is required at 50 Ohms. Consider the 0805 footprint for space-constrained PCB layouts. Evaluate the 100 mW power handling capability against system requirements. Verify that the 10 GHz frequency limit aligns with the operational bandwidth of the target application.

Part Context

This part belongs to the Susumu PAT series of thin-film chip resistors designed for RF applications. The series offers various attenuation values while maintaining consistent electrical characteristics. The PAT1220-C-10DB-T5 represents a specific variant optimized for high-frequency signal processing tasks requiring stable performance.

Replacement Considerations

TFA20C03DBER is listed as a parameter equivalent alternative by some distributors, though it specifies 3 dB attenuation. Verify exact electrical matching for 10 dB requirements before substitution.
