TC1-1-13M-75X+

Balun Overview

The TC1-1-13M-75X+ is a surface-mount RF transformer manufactured by Mini-Circuits, designed for high-frequency signal processing applications. It operates within a frequency range of 4.5 MHz to 3 GHz and features a 75 Ohm to 75 Ohm impedance configuration. The component utilizes a core and wire construction method, providing reliable performance in demanding environments. It is housed in an AT1521 package style, suitable for automated surface mount assembly processes. The device supports single-channel operation with a maximum DC current rating of 30 mA and a power rating of 250 mW. Operating temperatures range from -40°C to +85°C, ensuring stability across various industrial conditions.

Balun Feature Summary

• Provides balanced-to-unbalanced or unbalanced-to-balanced conversion capabilities through its 75 Ohm impedance design.
• Utilizes core and wire technology for robust signal integrity across wide bandwidths.
• Engineered for surface mount integration to facilitate compact circuit board layouts.

Balun Applications

• RF signal transmission systems requiring 75 Ohm impedance matching
• Broadband communication infrastructure components
• Test and measurement equipment signal conditioning

Balun Procurement Notes

Verify the specific suffix '75X+' against official Mini-Circuits documentation to confirm the 75 Ohm impedance variant. Ensure compatibility with AT1521 footprint requirements during PCB layout. Confirm RoHS compliance status via the manufacturer's latest environmental declarations. Cross-reference the part number with authorized distributors to validate authenticity and traceability before procurement.

Balun Selection Notes

Select this component when a 75 Ohm impedance transformation is required between 4.5 MHz and 3 GHz. Consider the AT1521 package dimensions for space-constrained designs. Evaluate thermal management needs given the 250 mW power rating and operating temperature limits. Compare against 50 Ohm variants if system impedance differs. Ensure the surface mount technology aligns with existing assembly capabilities.

Balun Part Context

This component belongs to the TC1 series of audio and signal transformers produced by Mini-Circuits. The series focuses on surface-mount solutions for RF and IF applications. The TC1-1-13M-75X+ specifically addresses 75 Ohm system requirements, distinguishing it from the standard 50 Ohm models like the TC1-1-13MX+. It represents a specialized variant within the broader portfolio of broadband transformers offered by the manufacturer.

Balun Replacement Considerations

The TC1-1-13M-75+ may serve as a lead-free alternative within the same impedance family. Verify pinout and dimensional compatibility before substitution. The TC1-1-13MG2+ offers similar electrical characteristics but with a different package size and 50 Ohm impedance, requiring circuit redesign.
