Introduction

In modern power electronics, the TDK LTF5022T-1R2N4R2-LC power inductor is pivotal for high-current, compact applications-especially in battery - related systems. As part of TDK's LTF series, it balances robust performance with reliability across diverse environments.

Technical Specs
With 1.2μH inductance (±30%) and 4.2A rated current, it thrives in high - power circuits. Its 25mΩ DCR minimizes energy loss, ideal for extending battery life in portable devices. Housed in a 5.2x5.0x2.2mm package, the ferrite - shielded design suppresses EMI and stabilizes inductance under heavy loads, operating from -40°C to +105°C.

Competitive Edge
15% lower DCR than Murata's LQH series reduces power drain on batteries. Its high saturation current fi

s space - tight battery packs, and RoHS 3 compliance aligns with eco - friendly designs.

Conclusion

The LTF5022T - 1R2N4R2 - LC's blend of high current handling, low DCR, and compact size makes it essential for next - gen battery - driven technologies, from EVs to renewable energy storage.
