CX2078NL

Balun Overview

The CX2078NL is an RF balun transformer manufactured by Pulse Electronics Corporation, designed for wideband applications. It operates within a frequency range of 5 MHz to 500 MHz and features a 1:1 impedance ratio with 50/50 Ohm configuration. The component utilizes a surface-mount 6-SMD Gull Wing package with physical dimensions of 4.3 mm in length, 2.69 mm in width, and 3.0 mm in height. It supports a minimum operating temperature of -40 °C and a maximum of 85 °C, with a maximum insertion loss of 2.5 dB.

Balun Feature Summary

• Provides single-ended to balanced signal conversion for RF circuits
• Supports wideband operation from 5 MHz to 500 MHz
• Utilizes a small surface mount gull wing package for efficient PCB integration

Balun Applications

• Wideband RF applications requiring signal balancing
• Single-ended to balanced circuit interfaces
• RF front-end modules in communication systems

Balun Procurement Notes

Verify the specific ordering suffix when procuring, as variants such as CX2078NLT may indicate tape and reel packaging while the base part number implies standard tube or bulk packaging. Confirm RoHS compliance status and lead-free requirements against current manufacturer specifications before finalizing orders. Ensure the supplier provides valid datasheets matching the exact part designation to avoid receiving obsolete or incompatible components.

Balun Selection Notes

Select this component for designs requiring a compact solution for wideband RF signal transformation between 5 MHz and 500 MHz. The 1:1 impedance ratio suits systems needing direct 50 Ohm to 50 Ohm conversion without additional matching networks. Consider the surface-mount gull wing footprint for automated assembly processes and verify thermal limits align with the operational environment constraints of the target application.

Balun Part Context

This component belongs to the Pulse Electronics audio and signal transformer product line, specifically categorized under RF transformers. It serves as a passive magnetic device used to balance unbalanced signals in radio frequency circuits. The series focuses on value-oriented construction suitable for high-volume manufacturing environments where space efficiency and consistent electrical performance are critical design parameters.
