4391-50

Attenuators Overview

The Pomona Electronics 4391-50 is a BNC male-to-female resistor attenuator designed for interconnect applications. It operates within a frequency range of 0 Hz to 500 MHz and provides a nominal attenuation of 50 Ohms. The device features a power rating of 2 W at 25°C and functions reliably within an operating temperature range of 0°C to +102°C. Constructed with Brass Alloy 360 (1/2 Hard), it ensures mechanical stability and signal integrity in RF test environments.

Attenuators Feature Summary

• Provides precise resistive attenuation via BNC male-to-female inline configuration
• Operates effectively across a wide frequency spectrum up to 500 MHz
• Constructed from tarnish-resistant Brass Alloy 360 for durability

Attenuators Applications

• RF signal level reduction in test and measurement setups
• Impedance matching between 50 Ohm components
• Protection of sensitive instrument inputs from high power signals

Attenuators Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Pomona Electronics or authorized distributors before procurement. Confirm that the 2 W power rating applies under the intended ambient temperature conditions, as derating may be required for operation above 25°C. Ensure connector compatibility with existing BNC infrastructure.

Attenuators Selection Notes

Select this component when a fixed 50 Ohm attenuation value is required for frequencies up to 500 MHz. It is suitable for applications needing robust brass construction and standard BNC connectivity. Consider thermal management if continuous operation exceeds 25°C, as the 2 W rating is specified at that baseline temperature.

Attenuators Part Context

This part belongs to the Pomona 4391 series of connectorized attenuators. These devices are engineered for general-purpose RF testing, offering reliable performance in laboratory and field environments. The series emphasizes mechanical durability and consistent electrical characteristics across the specified bandwidth.
