VLS201610CX-1R0M-1 Overview
A power inductor is a passive magnetic component that stores energy in a magnetic field when current flows through its winding. Within the passive-component hierarchy, it sits under inductors and coils, and serves as a core element of power management circuits: DC-DC converters, buck and boost regulators, filters, and energy-storage stages. Unlike unshielded or non-magnetic designs, the VLS201610CX-1 series uses a ferrite magnetic shield construction, which contains the magnetic flux and reduces electromagnetic coupling to neighboring circuits, enabling high-density mounting on crowded PCBs.
Key differentiating features of this part include its magnetic-shielded ferrite construction for low EMI in dense layouts, an optimized ferrite core geometry that TDK states achieves larger current capability and lower Rdc than earlier generations, a rated operating temperature range of -40C to +105C, and a tight 2.0 x 1.6 mm outline with a low profile suited to portable and space-constrained power stages. The M suffix denotes an inductance tolerance of +/-20%.
Technically, the wirewound drum-core architecture delivers low core losses at typical switching-frequencies used in mobile and embedded power supplies, while the ferrite shield minimizes flux leakage. TDK publishes an equivalent circuit model (TVCL) for the VLS201610CX-1 series, supporting accurate SPICE-level simulation of DC-DC converter ripple and transient behavior before layout.
Typical applications include the output or switching stage of buck converters in smartphones, tablets and wearables, power rails for WLAN and Bluetooth RF modules where shielded magnetics prevent coupling into sensitive receive paths, and general-purpose point-of-load regulation in industrial and consumer electronics. The 1 uH value with 2.14 A saturation covers common 1.8 V to 3.3 V point-of-load designs.
For design, verify that peak inductor current including ripple stays below the 2.14 A saturation rating, and note the Mouser-listed 1.76 A current rating for thermal margin; DC bias reduces effective inductance near saturation, so derating headroom of 20-30% is recommended in continuous-conduction-mode converters.

Typical Applications
VLS201610CX-1R0M-1 is suitable for 6 applications: Point-of-Load Buck Converter, Smartphone and Wearable Power Rails, WLAN / Bluetooth RF Module Supply, Industrial Control and Automation, IoT Sensor Nodes and Smart Home Devices, Display and Camera Module Power.
Point-of-Load Buck Converter
The VLS201610CX-1R0M-1's 1 uH inductance and 2.14 A saturation current make it a natural fit for the output energy-storage stage of 1.8 V to 3.3 V point-of-load buck regulators in embedded systems. Placed between the converter switch node and the output capacitor bank, it smooths the square-wave switching waveform into a DC rail; its 66 mOhm typical DC resistance limits conduction loss to roughly 0.19 W at a 1.7 A load. Because effective inductance rolls off near saturation, designers should keep peak current below 2.14 A and verify behavior under load transients using TDK's published equivalent circuit model.

Smartphone and Wearable Power Rails
In smartphones, tablets and wearables, board area is the scarcest resource, and the VLS201610CX-1R0M-1's compact 2.0 x 1.6 mm (0806/2016 metric) shielded footprint directly addresses that constraint while delivering 2.14 A capability. The ferrite magnetic shield suppresses stray flux that would otherwise couple into neighboring microphone, sensor or display-driver circuits, allowing placement closer to sensitive blocks than unshielded drum-core inductors permit. Its -40C to +105C range covers enclosed battery-powered devices with limited airflow, and the wirewound construction keeps DC resistance low enough for battery-runtime-sensitive rails.
Recommended
WLAN / Bluetooth RF Module Supply
RF transceiver modules such as WLAN and Bluetooth chipsets require clean, ripple-free supply rails, and the switching converter feeding them is a major noise source. The VLS201610CX-1R0M-1's magnetically shielded ferrite construction contains the switching-stage flux, preventing magnetic coupling into the 2.4 GHz receive path that would raise the noise floor and degrade sensitivity. With 1 uH inductance and 79 mOhm maximum Rdc, it forms a compact LC filter with output ceramics to attenuate switching ripple before the module's LDO or supply pin, making it a standard choice for high-density wireless PCB layouts.
Recommended
Industrial Control and Automation
Industrial controllers, PLC I/O modules and sensor nodes run 24/7 in electrically noisy environments, demanding robust power magnetics. The VLS201610CX-1R0M-1 suits 1-2 A point-of-load rails derived from 5 V or 24 V intermediate buses via downstream buck converters. Its shielded construction resists coupling with adjacent motor-driver or relay-switching circuits, and the -40C to +105C operating range covers unconditioned cabinets. At a 1.5 A continuous load the estimated conduction loss is about 0.15 W (I^2 x R using 66 mOhm typical), keeping thermal rise manageable in sealed enclosures without forced airflow.
Recommended
IoT Sensor Nodes and Smart Home Devices
Battery-powered and mains-adaptor-powered IoT nodes need efficient compact power conversion with low EMI near radios and MEMS sensors. The VLS201610CX-1R0M-1 supplies the 1 uH energy-storage element for 1-2 A burst-mode buck stages that charge supercapacitors or battery packs, while its shielding prevents magnetic interference with magnetometers and compass functions commonly integrated in smart home devices. The low 66 mOhm typical DC resistance maximizes conversion efficiency at light loads, and the 2.0 x 1.6 mm outline fits the dense multi-rail layouts typical of smart plugs, door locks and environmental sensor hubs.
Recommended
Display and Camera Module Power
Display drivers and camera module power trees combine several point-of-load rails generated near sensitive analog front ends. The VLS201610CX-1R0M-1's magnetic shield minimizes flux leakage into image-sensor bias lines and display gamma-correction circuitry, where coupled switching harmonics would appear as visible artifacts or banding. With 1 uH inductance at up to 2.14 A saturation, it supports backlight LED driver stages and AVDD rails of 1.2-2.8 V. Designers should place it with the shield oriented as recommended in TDK's datasheet and keep the switch-node loop short to contain radiated EMI.

Key Differentiators

- Simulation-ready equivalent circuit model (vs Comparable parts without published ECM)
Design Notes
Distinguish the two current ratings when sizing this inductor: 2.14 A is the saturation current (inductance droop limit) and 1.76 A is the thermal rating per the Mouser listing. In a continuous-conduction-mode buck converter, peak inductor current equals load current plus half the ripple; keep that sum below 2.14 A with margin. Estimated conduction loss at 1.7 A DC is I^2 x R = 1.7^2 x 0.066 = 0.19 W using the 66 mOhm typical Rdc - account for this in thermal budgets.
Follow the land pattern in TDK's VLS201610CX-1 datasheet exactly: the 2.0 x 1.6 mm terminations need pads sized for self-alignment during reflow. Keep the inductor in the tightest possible loop with the converter IC switch node and output capacitor to minimize radiated area. Although the ferrite shield reduces stray flux, avoid placing unsensitive magnetometers or high-impedance analog traces directly adjacent to the winding axis.
TDK's datasheet warns that post-mount soldering correction must stay within specified conditions - overheating during rework can cause short circuits, performance deterioration or lifespan shortening. Also note DC bias derating: effective inductance falls as current approaches the 2.14 A saturation point, so a converter sized at exactly the rating may show higher ripple than calculated. Verify with TDK's TVCL equivalent circuit model (published for this series) in SPICE before finalizing magnetics.
Compliance Information
Compliance data was not present in the verified web data. TDK commercial-grade power inductors are typically RoHS compliant, but this must be confirmed on TDK's product page before procurement. The series is designated commercial grade for power circuits, not automotive (not AEC-Q100 relevant).
