120085

Overview

The TPI 120085 is an individual BNC attenuator manufactured by Test Products International. It provides a fixed attenuation value of 20 dB with a power handling capacity of 0.5 Watt. The device operates within a frequency range of 0 Hz to 1 GHz and features a 50 Ohm impedance. Designed as a BNC in-line module, it utilizes standard BNC connectors for connection.

Feature Summary

• Provides fixed 20 dB signal attenuation
• Supports 0.5 Watt power handling
• Operates from DC to 1 GHz
• Features 50 Ohm impedance matching

Applications

• Increasing the input range of oscilloscopes
• RF signal level reduction in test setups
• Protecting sensitive measurement equipment from high power signals

Procurement Notes

Verify the manufacturer part number 120085 against official Test Products International documentation to ensure authenticity. Confirm that the received component matches the specified 20 dB attenuation, 0.5 Watt rating, and BNC interface. Check for physical damage to connectors and ensure compliance with RoHS standards if required by your procurement specifications.

Selection Notes

Select this component when a fixed 20 dB attenuation is required for frequencies up to 1 GHz. Ensure the application involves signals within the 0.5 Watt power limit. The BNC interface is suitable for standard laboratory and RF testing environments requiring 50 Ohm impedance systems.

Part Context

This model belongs to the TPI Individual BNC Attenuator series. It is designed as a standalone passive component for RF applications. The product line includes various attenuation values and kits, such as the TPI-1200 kit which contains multiple attenuators including this specific 20 dB unit.

Replacement Considerations

Compatible substitutes include other 20 dB BNC attenuators from manufacturers like Mini-Circuits or Pasternack, provided they meet the 0.5 Watt power and 1 GHz frequency requirements.
