Overview

The VLS252012HBX-100M-1 from TDK Corporation is a surface-mount fixed inductor designed for use in compact power and signal conditioning circuits. As a member of TDK’s VLS series, it is built in a low-profile SMD package suitable for high-density PCBs, such as DC-DC converter stages, power filtering, and energy storage in switching regulators. This inductor is optimized for stable inductance, low loss, and reliable performance in general-purpose electronics, telecom, and industrial equipment where compact size and consistent electrical characteristics are important. For exact inductance value, current rating, DC resistance, and saturation characteristics, please refer to the official TDK datasheet for VLS252012HBX-100M-1.

Applications

• Output and input filters in DC-DC converters for consumer and industrial electronics
• Energy storage inductors in point-of-load regulators on digital and CPU boards
• Power line noise suppression and EMI filtering in communication equipment
• Decoupling and ripple smoothing in battery-powered and portable devices
• General-purpose use in mixed-signal and analog front-end circuits requiring compact inductors
• Embedded control boards in automotive, factory automation, and instrumentation systems (within specified ratings)

Alternatives & Replacement

Depending on supply status, lifecycle, or specific electrical and mechanical requirements, designers may need to consider alternative inductors that offer similar inductance, current capability, DCR, and package size. Availability and cost can also drive selection of compatible substitutes.

Recommended alternatives:

• Murata Electronics North America – LQP03HQ7N5H02D (Redesign Required; check package and electrical specs)
• Murata Electronics North America – LQW15CN96NJ00D (Redesign Required; different characteristics and size)
• Murata Electronics North America – LQP03TN12NH02D (Redesign Required; verify inductance and current rating)
• Sunlord – SWPA5012S6R8MT (Redesign Required; different footprint and form factor)
• Sunlord – MCL1608S4R7MT (Redesign Required; confirm fit and performance)

Engineering note: All alternative parts listed are suggested on a “redesign required” basis. Before substitution, carefully compare the datasheets for inductance value and tolerance, rated current, saturation current, DC resistance, self-resonant frequency, package size, and land pattern. Ensure PCB footprint, height clearance, thermal behavior, and reliability targets are compatible with your original design.
