Monolithic Power Systems Inc. EVSK-002

Overview

EVSK-002 from Monolithic Power Systems is a power inductor sample kit containing 15 molded inductors from the MPL-AY series in 3020 and 4020 case sizes, covering inductance values from 0.47 µH to 10 µH, with DC resistance as low as 19.5 mΩ and saturation current up to 9 A, designed for high-current, high-frequency DC-DC converters in portable and battery-powered systems.

For engineers reviewing the EVSK-002 datasheet, EVSK-002 contents, EVSK-002 application, or EVSK-002 equivalent, this kit supports rapid prototyping of POL, SMPS, and input filter designs requiring verified low-DCR, soft-saturation, and high-temperature-stable inductors across two standardized footprints.

Technical Context

The EVSK-002 contains 15 discrete molded power inductors-12 in 3020 (3.0 × 2.0 mm) and 3 in 4020 (4.0 × 2.0 mm) packages-each featuring composite magnetic cores, copper alloy windings, and overmolded epoxy encapsulation. All units are RoHS/REACH-compliant and halogen-free.

Inductors in this kit support switching frequencies up to 2 MHz, exhibit soft saturation behavior (gradual inductance roll-off under DC bias), and maintain stable performance from –40°C to +125°C ambient, enabling use in thermally constrained POL and high-efficiency SMPS designs.

Key Specifications

Supply support for EVSK-002 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) is a fabless semiconductor company specializing in high-performance power management ICs and passive components, headquartered in Kirkland, WA, with global design and support operations.

The MPL-AY series was developed to deliver high-current, low-noise, molded power inductors optimized for compact, high-efficiency DC-DC conversion in space-constrained applications such as portable electronics and distributed power architectures.

FAQ

What inductors are included in the EVSK-002 kit?

The kit contains 15 pre-selected MPL-AY series molded inductors: twelve 3020-size parts (0.47 µH to 10 µH) and three 4020-size parts (5.6 µH to 10 µH), all with verified DCR, ISAT, and IR ratings published in the official MPS datasheet Rev. 1.0.

Are the inductors in EVSK-002 lead-free and RoHS-compliant?

Yes. All MPL-AY inductors in EVSK-002 are lead-free, halogen-free, and fully compliant with RoHS and REACH directives, as confirmed in the MPS product documentation and packaging labeling.

Can EVSK-002 be used for automotive-grade prototyping?

No. While the MPL-AY series operates from –40°C to +125°C, EVSK-002 contains standard industrial-grade inductors without AEC-Q200 qualification or automotive-specific traceability; it is intended for commercial and portable electronics evaluation only.

What is the physical size of the EVSK-002 sample kit packaging?

The kit ships in a rigid plastic tray measuring 200 mm × 36 mm × 140 mm (L × H × W), with labeled compartments for each of the 15 inductors, including part number labels and orientation indicators per unit.

Does EVSK-002 include test reports or reliability data?

No. The kit includes only physical inductors and a printed reference sheet listing order codes and basic parameters. Full reliability data, thermal imaging, and life-test results are available separately in the official MPL-AY series datasheet on monolithicpower.com.
