T-622-KK81+

Balun Overview

The T-622-KK81+ is a 1:1:1 core and wire RF transformer manufactured by Mini-Circuits. It operates within a frequency range of 0.1 MHz to 200 MHz with a characteristic impedance of 50 Ohms. The component utilizes SMD/SMT termination types and is available in cut tape, MouseReel, or reel packaging formats. It supports a maximum current rating of 30 mA and a power rating of 250 mW. The device functions reliably across an operating temperature range from -20°C to +85°C.

Balun Feature Summary

• Provides balanced-to-unbalanced signal conversion using a 1:1:1 core and wire configuration
• Supports wideband operation from 0.1 MHz to 200 MHz for versatile RF applications
• Features surface-mount design compatible with automated assembly processes

Balun Applications

• RF signal balancing and unbalancing circuits
• Audio and signal transformer implementations
• Impedance matching networks in communication systems

Balun Procurement Notes

Verify the specific ordering suffix KK81 to ensure correct termination style and package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability and lead times directly with authorized distributors as supply levels fluctuate. Ensure storage conditions align with specified temperature limits to maintain component integrity during handling.

Balun Selection Notes

Select this component when a compact, wideband transformer is required for frequencies up to 200 MHz. The 1:1:1 ratio makes it suitable for direct impedance matching without transformation gain. Consider the physical dimensions and SMT footprint for PCB layout constraints. Evaluate thermal performance against the 250 mW power rating for high-signal environments.

Balun Part Context

This part belongs to the T-series of RF transformers from Mini-Circuits, designed for general-purpose signal processing. It complements other models like the T1-6-KK81+ which covers lower frequencies down to 10 kHz. The series emphasizes robust construction and consistent electrical performance across varying environmental conditions.

Balun Replacement Considerations

Direct substitutes include T-622-X65+ for alternative packaging variants within the same electrical specification. Cross-reference with T-622-KK81 (non-plus) if lead-free certification is not strictly required. Verify pin compatibility and mounting dimensions before substituting with similar balun components.
