CX2049LANLT

Balun Overview

The CX2049LANLT is an RF balun transformer manufactured by Pulse Electronics, designed for balanced-to-unbalanced signal conversion. It operates within a frequency range of 250kHz to 500MHz and utilizes a 5-SMD surface-mount package with physical dimensions of 3.81mm x 3.81mm x 2.79mm. Key electrical specifications include a maximum insertion loss of 3.0dB and a minimum return loss of 8dB. The component supports an operating temperature range from -40°C to +85°C and complies with RoHS3 standards.

Balun Feature Summary

• Provides balanced-to-unbalanced signal transformation for RF applications
• Miniature surface mount package suitable for space-constrained designs
• Wideband operation covering frequencies from 250kHz to 500MHz

Balun Applications

• Balanced-to-unbalanced circuit interfaces in RF systems
• Wideband RF application signal conditioning
• Miniaturized electronic device integration requiring SMD components

Balun Procurement Notes

Verify the specific suffix 'LT' corresponds to tape-and-reel packaging when ordering. Confirm that the 5-SMD footprint matches the target PCB layout dimensions of 3.81mm by 3.81mm. Ensure the design accommodates the specified operating temperature range of -40°C to +85°C. Check for RoHS3 compliance requirements against project specifications.

Balun Selection Notes

Select this component when a wideband balun is required between 250kHz and 500MHz. The 3.0dB insertion loss limit defines its efficiency threshold compared to lower-loss alternatives like the CX2049LNLT. The 5-SMD package dictates the available mounting area on the circuit board. Consider the impedance ratio characteristics if interfacing with specific transmission line impedances.

Balun Part Context

This part belongs to the Pulse Electronics CX2049L series of miniature RF transformers. It shares the same physical footprint and general frequency range as variants such as the CX2049LNLT, though performance metrics like insertion loss differ. The series is characterized by small surface-mount packages intended for high-density PCB assembly in wireless communication equipment.

Balun Replacement Considerations

The CX2049LNLT serves as a verified alternative within the same series, offering improved insertion loss performance while maintaining identical physical dimensions and frequency coverage.
