141-3901-810

Overview

The Cinch Connectivity Solutions Johnson 141-3901-810 is a fixed SMA RF attenuator designed for in-line module applications. It provides a nominal attenuation of 10 dB with a 50 Ohm impedance. The component supports a frequency range from 0 Hz to 6 GHz and features SMA connectors on both ends. It has a power rating of 2W, ensuring reliable performance in high-frequency signal processing environments.

Feature Summary

• Fixed 10 dB attenuation value for precise signal reduction
• SMA connector interface for standard coaxial integration
• 50 Ohm impedance matching for system compatibility
• In-line module form factor for direct circuit insertion

Applications

• RF signal path attenuation in test and measurement equipment
• Signal level adjustment in wireless communication systems
• Impedance matching networks in microwave circuits
• Protection of sensitive receiver inputs from high power signals

Procurement Notes

Verify the current availability status as some sources indicate discontinuation. Confirm the specific power rating (1W vs 2W) against the official datasheet before procurement. Ensure the SMA connector type matches the system requirements. Check for any ordering suffix variations that may affect specifications. Validate the manufacturer part number directly with authorized distributors.

Selection Notes

Select this component when a fixed 10 dB attenuation is required at 50 Ohms within the 6 GHz bandwidth. Consider the in-line module format for easy integration into existing SMA cabling infrastructure. Evaluate thermal management capabilities based on the specified power rating. Compare against variable attenuators if adjustable signal levels are needed instead.
