Frequently Asked Questions
What inductance and rated current does the CLF7045T-150M support for switching regulator designs?
The TDK CLF7045T-150M features 15 µH inductance at ±20% tolerance and handles up to 2.3 A of rated DC current, making it well-suited for output chokes in switching regulators operating between 100 kHz and 2 MHz switching frequencies.
How does the magnetically shielded design of the CLF7045T-150M reduce EMI in compact power modules?
The CLF7045T-150M's magnetically shielded ferrite core contains magnetic flux within a 7.0 × 4.5 mm footprint, reducing radiated EMI by more than 20% compared to unshielded inductors and enabling cleaner power rails in noise-sensitive applications such as wireless IoT modules.
What DC resistance does the CLF7045T-150M have and how does it affect power-converter efficiency?
The CLF7045T-150M has a DC resistance of 0.051 ohm, resulting in a conduction loss of approximately 270 mW at the rated 2.3 A, which helps switching regulators maintain efficiency above 90% in typical DC-DC converter output stages.
When should the CLF7045T-150M be chosen over a lower-inductance alternative in a buck converter?
When a buck converter operates at 100 kHz to 500 kHz and requires 2.3 A continuous output current with low ripple, the CLF7045T-150M's 15 µH inductance provides sufficient energy storage to keep output voltage ripple below 1% in typical designs.
