What are the key features of LPE4841SM100MG?
- 100 µH inductance value in a surface mount package optimized for DC-DC converter filter stages
- Magnetically shielded gapped core design minimizes EMI and reduces coupling to nearby components
- Operating temperature range of -40°C to +125°C supports automotive and industrial power supply designs
- Low DC resistance (DCR) construction maximizes efficiency in high-frequency switching regulator applications
What is LPE4841SM100MG used for?
The LPE4841SM100MG is used as the output filter inductor in buck, boost, and flyback DC-DC converters operating in the 100 kHz to 1 MHz switching frequency range. Its 100 µH inductance and shielded SMD construction make it suitable for noise-sensitive applications such as automotive infotainment power rails, industrial sensor power supplies, and portable medical device converters. The part's reflow-compatible surface mount footprint simplifies automated PCB assembly in space-constrained designs.

Frequently Asked Questions
What inductance value does the Vishay LPE4841SM100MG provide, and in which converter topology is it most effective?
The LPE4841SM100MG provides 100 µH of inductance. This value is well suited for output filter stages in buck and boost DC-DC converters switching between 100 kHz and 500 kHz, where it limits output ripple current to acceptable levels and maintains efficiency across load currents typical of embedded system power rails.
How does the shielded core of LPE4841SM100MG benefit PCB layout in noise-sensitive designs?
The magnetically shielded gapped core confines the inductor's magnetic field within the component, reducing radiated EMI to nearby analog circuits and RF modules. This allows designers to place the LPE4841SM100MG closer to sensitive circuitry on a 4-layer PCB without requiring additional shielding cans, lowering overall BOM cost while meeting CISPR 25 or EN 55032 radiated emission limits.
What operating temperature range does the LPE4841SM100MG support, and what markets does this cover?
The LPE4841SM100MG operates from -40°C to +125°C, covering both automotive and standard industrial temperature requirements. This range qualifies it for under-hood automotive power modules, outdoor industrial controls, and avionics ancillary power supplies where ambient temperatures routinely exceed the +85°C commercial limit.
Is the LPE4841SM100MG suitable for automated SMT production, and what package dimensions should designers plan for?
Yes, the LPE4841SM100MG uses a standard SMD footprint compatible with pick-and-place assembly and reflow soldering processes. The LPE4841 package measures approximately 12.2 mm × 12.2 mm × 8.0 mm, so designers should reserve adequate keep-out clearance on both the top and bottom copper layers to accommodate the component height and the magnetically shielded core boundary.
