Monolithic Power Systems Inc. EVSK-005

Overview

EVSK-005 from Monolithic Power Systems is a power inductor sample kit containing 27 semi-shielded molded inductors across three footprints (4030, 5040, 6040), each with verified inductance (1.0–22 µH), DCR (9.4–219 mΩ), and saturation current (1.5–10.5 A). It supports rapid prototyping of DC-DC converters in portable and embedded power systems.

For engineers reviewing the EVSK-005 datasheet, EVSK-005 contents, EVSK-005 application, or EVSK-005 equivalent, this kit enables fast comparative evaluation of MPL-SE series inductors for buck converter output filtering, battery-powered SMPS design, and high-current input stage selection-prior to volume procurement.

Technical Context

The EVSK-005 contains only pre-characterized, production-grade MPL-SE series inductors-no evaluation circuitry or active components. Each part uses semi-shielded construction with magnetic epoxy encapsulation to suppress stray fields while maintaining thermal performance up to 125°C ambient.

All included inductors are RoHS/REACH-compliant, halogen-free, and rated for continuous DC bias operation. Inductance tolerance is ±20%, and self-resonant frequencies range from 12 MHz (MPL-SE4030-220) to 85 MHz (MPL-SE6040-1R5), validated per IEC 62137-1.

Key Specifications

Availability

Supply support for EVSK-005 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Monolithic Power Systems (MPS) designs high-performance analog and power semiconductor solutions, specializing in integrated DC-DC converters, LED drivers, and magnetics for energy-efficient power systems.

The MPL-SE series-featured in EVSK-005-is engineered for high-current, low-profile buck converter output stages where controlled saturation behavior and minimal EMI are critical in space-constrained battery-powered applications.

FAQ

What inductors are included in the EVSK-005 kit?

The kit contains 27 production-ready MPL-SE series inductors: nine 4030-size (1.0–15 µH), nine 5040-size (1.0–22 µH), and nine 6040-size (1.5–22 µH), all with full electrical characterization data provided in the Rev. 1.0 datasheet.

Is EVSK-005 a functional evaluation board or a passive component sample kit?

EVSK-005 is strictly a passive component sample kit-no PCB, no circuitry, no active devices. It delivers bare inductors in labeled static-safe packaging, intended for direct integration into customer prototype boards or test fixtures.

Can EVSK-005 be used for automotive-grade design validation?

No-MPL-SE parts in EVSK-005 are qualified for industrial and commercial temperature ranges (–40°C to +125°C), not AEC-Q200. For automotive applications, MPS offers the MPL-AL and MPL-AY series with full AEC-Q200 qualification.

Are the inductors in EVSK-005 tape-and-reel or loose samples?

All 27 inductors are supplied as loose, individually labeled samples in anti-static trays-not tape-and-reel. Each part is marked with its order code (e.g., "MPL-SE4030-1R0") and matches the exact specifications listed in the official MPS datasheet.

Does EVSK-005 include measurement fixtures or test reports?

No. The kit contains only the inductors and a printed reference sheet listing part numbers, L, DCR, ISAT, and IR values. No fixtures, LCR meter calibration standards, or third-party test reports are included.

How does MPL-SE's semi-shielded construction differ from fully shielded inductors?

MPL-SE uses magnetic epoxy over-molding that suppresses >85% of stray flux versus unshielded types, while retaining lower core loss and higher saturation current than fully shielded drum-core alternatives-ideal for high-efficiency, thermally sensitive layouts.
