27-9300-3

Overview

The Cinch Connectivity Solutions 27-9300-3 is a fixed coaxial attenuator designed for RF applications. It provides a nominal attenuation of 3 dB with a power rating of 1/2 W at 5% tolerance. The device operates within a frequency range of 0 to 2 GHz and maintains a characteristic impedance of 50 Ohms. It features BNC connectors, specifically a male plug to female socket interface. The housing is nickel-plated brass with gold-plated brass contacts. It functions in a straight configuration and supports an operating temperature range from -55°C to 85°C.

Feature Summary

• Provides precise 3 dB signal attenuation for RF circuitry
• Features robust BNC male-to-female connectivity
• Constructed with nickel-plated brass housing and gold contacts

Applications

• RF signal level reduction in test and measurement equipment
• Impedance matching in 50 Ohm transmission lines
• Signal conditioning in communication systems

Procurement Notes

Verify the specific connector polarity matches the system requirement, as this model specifies a male plug to female socket configuration. Confirm that the 1/2 W power rating and 3 dB attenuation value align with the target application's signal strength needs. Ensure the operating temperature range of -55°C to 85°C is sufficient for the intended environment. Check for RoHS compliance status if required by project specifications.

Selection Notes

Select this component when a fixed 3 dB attenuation is required in a 50 Ohm system using BNC interfaces. It is suitable for frequencies up to 2 GHz. Consider the physical straight orientation and the specific male-to-female connection type during integration. Evaluate the thermal performance against the 1/2 W power handling capability to ensure reliable operation under expected load conditions.

Part Context

This part belongs to the Cinch Connectivity Solutions line of coaxial attenuators, which are engineered for high-reliability interconnect technologies. The brand has over 60 years of experience providing rugged solutions for mission-critical defense and industrial applications. This specific model represents a standard fixed attenuator pad within their broader portfolio of RF components.

Replacement Considerations

The 27-9300-6 (6 dB) and 27-9300-10 (10 dB) are related models in the same series offering different attenuation values but sharing similar BNC connector types and general construction characteristics.
