What are the key features of CLF12577NIT-470M-D?
- 47 µH inductance with only 0.066 Ω DCR minimizes I²R conduction losses in DC-DC converter output filter stages
- Shielded ferrite core construction suppresses EMI radiation, meeting conducted emissions requirements in sensitive power supply designs
- Large 5049 case (12.5 × 12.5 × 7.7 mm) supports high saturation current, enabling use in high-power motor drive and server power modules
What is CLF12577NIT-470M-D used for?
The CLF12577NIT-470M-D is optimized for output filter inductors in DC-DC buck and boost converters operating at switching frequencies from 100 kHz to 500 kHz in industrial power supplies and server power delivery modules. Its shielded construction and low 0.066 Ω DCR make it well suited for high-current automotive and telecom power stages where both low losses and EMI compliance are required.

Frequently Asked Questions
What are the inductance, DCR, and package size of the TDK CLF12577NIT-470M-D?
The CLF12577NIT-470M-D provides 47 µH of inductance at ±20% tolerance with a very low DC resistance of 0.066 Ω. It is housed in a 5049 SMD case measuring 12.5 × 12.5 × 7.7 mm, making it one of TDK's larger power inductors optimized for low-loss, high-current DC-DC converter output stages.
How does the shielded ferrite core of the CLF12577NIT-470M-D help with EMI compliance in switching power supplies?
The shielded ferrite core confines the magnetic flux within the inductor body, reducing radiated EMI by more than 20 dB compared with unshielded wire-wound inductors at switching frequencies of 100 kHz to 500 kHz. This makes it easier to pass CISPR 32 Class B or FCC Part 15 conducted emissions limits without additional shielding cans.
For which power conversion topologies is the CLF12577NIT-470M-D best suited compared with a smaller 2520 package inductor?
The 5049 package of the CLF12577NIT-470M-D supports significantly higher saturation current than a 2520 package inductor of the same 47 µH value, making it the preferred choice for high-power synchronous buck converters with output currents above 5 A, such as 12 V to 5 V or 24 V to 12 V server board power rails where efficiency and thermal headroom are critical.
