Key Features
- 2700 µH high inductance value supports low-ripple filtering in DC/DC converters operating at frequencies below 100 kHz
- Ferrite rectangular core construction (4747 case) enables high energy storage with low saturation distortion
- 2.38 Ω DCR balances conduction loss against inductance in cost-sensitive power inductor designs
Applications
The MSS1210-275KEB is used in low-frequency DC/DC converters, EMI filter chokes, and energy storage stages in industrial power supplies where a 2700 µH inductance with a 2.38 Ω DC resistance is required. Its rectangular ferrite core construction makes it suitable for line-frequency filtering in smart meters, motor control pre-regulators, and battery charger input stages. Engineers also specify it in low-power buck-boost converters and PFC front-end circuits operating below 100 kHz.

Frequently Asked Questions
What is the inductance and DC resistance of the MSS1210-275KEB?
The MSS1210-275KEB has a nominal inductance of 2700 µH and a DC resistance of 2.38 Ω, making it well suited for low-frequency power filtering applications where high inductance per unit volume is prioritized over low conduction loss.
Which switching converter topologies benefit from the 2700 µH inductance of MSS1210-275KEB?
Buck and buck-boost converters operating below 100 kHz benefit most from the 2700 µH inductance of MSS1210-275KEB, as the high inductance keeps output current ripple below 10% of rated load current even at switching frequencies as low as 20 kHz.
What package size does MSS1210-275KEB use and how does it affect board layout?
MSS1210-275KEB uses a rectangular 4747 SMD case (approximately 12 mm x 10 mm footprint), which requires a PCB land area of roughly 120 mm² and offers a stable low-profile mounting suitable for automated pick-and-place assembly.
How does the ferrite core material of MSS1210-275KEB perform in EMI filter applications?
The ferrite core provides high permeability that sustains 2700 µH inductance up to its saturation current, effectively attenuating conducted EMI above 10 kHz by more than 20 dB in typical LC filter configurations used in industrial power supplies.
