VLS201610CX-2R2M-1 Overview
A power inductor is a passive energy-storage component that stores energy in a magnetic field when current flows through its winding. Within the passive-component hierarchy (inductor -> coil -> magnetic component), power inductors sit at the heart of every switching regulator, where they smooth current ripple, transfer energy between switching cycles, and filter high-frequency noise. The VLS-CX-1 series from TDK is optimized for these DC-DC conversion roles.
Key features of the VLS201610CX-2R2M-1 include a magnetically shielded drum-core construction that contains flux and minimizes crosstalk with neighboring components, enabling high-density mounting; ferrite-core wirewound architecture delivering low core losses at the 1 MHz test frequency; and optimized ferrite core geometry that, according to TDK, achieves larger current capability and lower Rdc compared with earlier VLS generations.
The inductance is measured at 1 MHz with a 20% tolerance band, and the saturation current specification (1.31 A per distributor parametric data) defines the point where inductance begins to fall due to core saturation. The wirewound construction provides predictable, stable DCR of 163 mOhm max, which directly determines conduction losses: Estimated: at a 1 A DC load, copper loss is approximately I^2 x DCR = 1 A x 1 A x 0.163 Ohm = 163 mW, which drives both efficiency and temperature-rise calculations.
Typical applications include output chokes and energy-storage inductors in buck converters for FPGAs, MCUs and SoC power rails (including Intel/Altera and Xilinx power trees), point-of-load converters in networking and server equipment, and RF or audio bias-feed filtering where a shielded construction prevents magnetic coupling into sensitive signal paths.
Design consideration: verify that the peak current (load current plus half the inductor ripple current) remains below the saturation rating rather than the thermal rating, and keep the part away from unshielded inductors to avoid mutual coupling.

Typical Applications
VLS201610CX-2R2M-1 is suitable for 6 applications: FPGA / SoC Point-of-Load Buck Converter, Portable and Wearable DC-DC Power, Networking and Telecom Equipment, RF and Precision Analog Bias Filtering, Consumer Electronics Power Rails, IoT Sensor Nodes and Smart Home Modules.
FPGA / SoC Point-of-Load Buck Converter
The VLS201610CX-2R2M-1 serves as the energy-storage or output inductor in low-power buck regulators feeding FPGA and SoC core or I/O rails. Its 2.2 uH inductance at 1 MHz and 1.53 A rated current suit rails drawing up to roughly 1 A, while the 163 mOhm max DCR keeps conduction losses below 163 mW at 1 A. The shielded construction prevents magnetic coupling into adjacent high-speed FPGA signal routing, which matters in dense 2.0 x 1.6 mm layouts. Place the inductor between the switch node and the output capacitor bank with short, wide copper to minimize parasitic ringing, and confirm peak current (load plus half ripple) stays below the 1.31 A saturation rating.
Recommended
Portable and Wearable DC-DC Power
In battery-powered portable devices, the VLS201610CX-2R2M-1 provides compact power conversion with its 2.0 x 1.6 mm, low-profile shielded package suited to space-constrained wearables and handheld electronics. The 2.2 uH value supports switching frequencies around 1 to 4 MHz, enabling small output capacitors and further size reduction. Its ferrite wirewound core delivers predictable losses at 1 MHz, and the 163 mOhm DCR limits quiescent heating that would drain battery life. Designers should budget the 20% inductance tolerance into ripple calculations and keep load peaks below 1.31 A saturation to avoid inductance roll-off during transmit or burst modes.
Recommended
Networking and Telecom Equipment
The VLS201610CX-2R2M-1 filters supply rails and serves as a buck choke in switches, routers and optical modules, where many 1 to 2 A rails coexist in tight quarters. TDK designed the VLS-CX series for high-density mounting, and the high magnetic-shield construction documented on Mouser's product page minimizes crosstalk between neighboring inductors on the same board. At 1 MHz test frequency the ferrite core shows low losses appropriate for MHz-class converters. Place shielded inductors with terminations oriented away from sensitive SerDes or PHY supplies; the shield contains most flux but leakage at the winding ends still warrants spacing in dense multi-rail layouts.
Recommended
RF and Precision Analog Bias Filtering
Shielded construction makes the VLS201610CX-2R2M-1 suitable as an RF choke or bias-feed inductor feeding PLLs, VCOs and low-noise amplifier supply pins, where an unshielded inductor's stray field would couple into adjacent signal lines and degrade phase noise or noise figure. The ferrite core's behavior at 1 MHz and the wirewound topology give a predictable impedance profile for low-frequency supply filtering, while the 163 mOhm DCR introduces only modest DC drop at sub-amp bias currents. Pair with ferrite beads or pi-filter capacitors for wider-band attenuation, and verify self-resonant behavior at your operating frequency from the full impedance curves in the TDK datasheet.
Recommended
Consumer Electronics Power Rails
In consumer products such as set-top boxes, displays and smart-home hubs, the VLS201610CX-2R2M-1 provides cost-effective 2.2 uH power inductance for mainstream buck converters. Its RoHS-compliant, lead-free termination (Pb under 0.1% per JEDEC JESD97) satisfies global environmental regulations, and availability from LCSC at $0.0459 as of 2026-09-06 plus multi-distributor stock (over 22,000 pieces across Arrow channels) secures supply for volume production. The 20% tolerance is adequate for non-critical rails; for precision core rails, budget the tolerance band into worst-case ripple and loop-gain simulations. JLCPCB assembly support simplifies prototype bring-up.
Recommended
IoT Sensor Nodes and Smart Home Modules
The VLS201610CX-2R2M-1 fits IoT sensor nodes, wireless modules and smart-home controllers that run from single-cell Li-ion or USB supplies and need small, efficient buck conversion. At sub-500 mA average loads the 163 mOhm DCR dissipates only about 40 mW, preserving battery runtime, and the 1.53 A rating leaves headroom for radio transmit bursts. The magnetically shielded drum core prevents interference with nearby antennas and crystal circuits in tight RF module layouts. Designers should verify that burst-mode peak currents plus ripple remain under the 1.31 A saturation specification and select the 2.2 uH value with the converter's recommended inductance range for the target switching frequency.

Key Differentiators
- Verified transparent parametrics (vs Cross-brand 2016-size equivalents)
- High magnetic shielding in 2.0 x 1.6 mm (vs VLS201610CX-2R2M (identical))
- Supply-chain flexibility via ordering-code variants (vs VLS201610CX-2R2M)
Design Notes
Size the inductor by saturation, not just thermal rating: peak current equals load current plus half the ripple current, and the VLS201610CX-2R2M-1 saturates at 1.31 A even though its thermal rating is 1.53 A. Estimated: in a 3.3 V to 1.8 V, 1 MHz buck at 0.8 A load with 20% ripple, peak current is 0.88 A - comfortably below 1.31 A, leaving margin for transient overshoot. If your converter allows load transients above 1.2 A peak, step up to a larger VLS series size to avoid inductance collapse and ripple runaway.
Follow TDK's recommended 2016 land pattern exactly; the wide end terminations of this drum-core wirewound part need adequate pad area for reliable reflow fillets. Place the inductor at the switching node with short, wide traces to the converter IC and output capacitors to reduce parasitic inductance and EMI. Although the part is magnetically shielded, route feedback and analog traces away from the body - leakage flux at the winding ends can still couple noise. Provide thermal copper pour connected to the pads since heat exits through the terminations.
Do not assume the -1 suffix changes electrical behavior - it is a taping/ordering code, so VLS201610CX-2R2M and VLS201610CX-2R2M-1 are interchangeable. Also, the 20% inductance tolerance means worst-case value spans 1.76 to 2.64 uH; run loop compensation and ripple calculations across this band. Finally, verify the datasheet self-resonant frequency at your operating conditions before using the part as a filter element above its intended power-conversion frequency range.
