PFL2015-682MEC 개요
A shielded power inductor is a wire-wound passive component that stores energy in a magnetic field while providing low core losses and excellent EMI containment through a magnetic shield (typically a ferrite casing or core geometry). In modern power-supply design, shielded inductors sit between the discrete inductor and the integrated power module: they outperform unshielded wire-wound parts in EMI-sensitive layouts and offer a smaller footprint than toroidal equivalents. The PFL2015 family belongs to the broader molded-power-inductor category, which itself traces up the hypernym chain to power inductors → inductors → passive components.
Key features of the PFL2015-682MEC include a 20% inductance tolerance, soft saturation behavior that tolerates high peak currents, magnetic shielding for high-density PCB layouts, and an AEC-Q200 grade-1 automotive qualification (-40 °C to +125 °C) that suits under-hood and ADAS power trees. The molded construction eliminates audible buzzing under high-ripple conditions.
Architecturally, the PFL2015-682MEC uses a low-loss ferrite core geometry optimized for sub-100 MHz switching frequencies, with a single-wire-wound coil terminated to flat solderable pads. Compared to non-shielded inductors of equivalent rating, the magnetic shield reduces near-field coupling by more than 10 dB at 1 cm, eliminating the need for keep-out zones around noise-sensitive analog rails.
Typical applications include smartphone PMIC output filtering, IoT sensor-node buck converters, automotive infotainment power rails, USB-PD adapters, and wearable-device battery-management modules. The AEC-Q200 rating makes it especially attractive for ADAS camera modules and instrument-cluster power supplies.
When designing with this part, derate Irms by 30% above 85 °C ambient, and ensure the PCB land pattern matches Coilcraft's recommended 2.5 x 1.7 mm footprint with reflow profile per J-STD-020. The molded body tolerates standard lead-free reflow up to 260 °C peak for 30 seconds.

일반적인 애플리케이션
PFL2015-682MEC 적합 용도: 6 애플리케이션s: Automotive ADAS Camera Power Supply, Smartphone PMIC Output Filter, IoT Sensor Node DC-DC Converter, USB-PD Adapter Output Stage, Wearable Device Battery Management, Industrial Sensor Module Power Tree.
Automotive ADAS Camera Power Supply
The PFL2015-682MEC is well-suited for ADAS camera module buck converters where its 6.8 µH inductance, 680 mA saturation, and AEC-Q200 Grade 1 qualification directly meet automotive requirements. Typical designs operate at 2 MHz switching frequency with 3.3 V or 5 V output rails, where the inductor's 400 mΩ DCR limits conduction loss to 0.18 W at full load. The magnetic shield eliminates the need for keep-out zones around the CMOS image sensor's analog supply rail, reducing PCB area by approximately 15% compared to non-shielded alternatives. Coilcraft's molded construction prevents audible buzzing under high-ripple conditions, which is critical for in-cabin camera modules.

Smartphone PMIC Output Filter
In smartphone power management IC (PMIC) designs, the PFL2015-682MEC serves as the output filter for sub-regulators powering application processors, RF transceivers, and memory subsystems. The 2.2 x 1.4 mm package is among the smallest AEC-Q200 qualified inductors available, allowing designers to meet stringent board-area constraints in flagship handsets. At 680 mA continuous rating, it supports 1-2 A peak loads typical of CPU boost events, with the molded construction providing robust mechanical reliability during drop testing. The 6.8 µH value is ideal for 1-2 MHz switching frequencies common in modern PMIC architectures.

IoT Sensor Node DC-DC Converter
The PFL2015-682MEC fits IoT sensor-node designs where low quiescent current, small footprint, and AEC-Q200 grade are valued for industrial and smart-building applications. Battery-powered wireless sensor nodes operating from 3.6 V Li-SOCl2 cells typically draw 50-300 mA average load, well within the inductor's 680 mA rating. The 6.8 µH inductance supports 500 kHz to 2 MHz switching frequencies, enabling small external ceramic capacitors and reducing BOM cost. The shielded construction prevents coupling to nearby RF antennas, which is critical for sub-GHz and 2.4 GHz radio coexistence in dense sensor arrays.
추천
USB-PD Adapter Output Stage
USB Power Delivery (USB-PD) adapters operating at 5 V, 9 V, 12 V, and 15 V output levels benefit from the PFL2015-682MEC's 6.8 µH inductance and 680 mA continuous rating. While PD adapters typically require higher currents, the PFL2015 family supports auxiliary rails such as VCONN, CC communication supply, and standby power in travel adapters. The AEC-Q200 grade provides additional reliability margin in commercial adapters, and the magnetic shield reduces radiated EMI - helping designs meet EN 55022 Class B without complex shielding cans. The molded body tolerates the 260 °C reflow profile required for lead-free assembly.

Wearable Device Battery Management
Wearable health monitors and smartwatches require miniature power inductors for battery charging and step-down conversion in extremely space-constrained designs. The PFL2015-682MEC's 2.2 x 1.4 mm footprint is ideally suited for these applications, fitting alongside 0201 and 0402 passives on high-density wearable PCBs. The 6.8 µH value suits 1.8 V and 3.3 V rails for AMOLED displays, heart-rate sensors, and BLE radios. The molded construction withstands the mechanical stress of wearable use cases, and the soft saturation characteristic handles the current spikes of display refresh events without audible noise.

Industrial Sensor Module Power Tree
Industrial 4-20 mA sensor modules, isolated data acquisition systems, and PLC I/O subsystems benefit from the PFL2015-682MEC's wide -40 °C to +125 °C operating range and AEC-Q200 qualification. These systems often operate from 24 V industrial buses and require 3.3 V or 5 V rails for microcontrollers and analog front-ends. The 680 mA rating supports multi-rail configurations where a single buck converter powers multiple sensors. The magnetic shield prevents coupling to sensitive analog measurement circuits - critical for 16-bit and 24-bit ADC-based sensor designs where power-supply noise directly degrades measurement accuracy.

설계 노트
At the maximum 680 mA Irms rating, the PFL2015-682MEC dissipates approximately 0.18 W (I²R loss in the 400 mΩ DCR), causing a 40 °C temperature rise above 25 °C ambient per the Coilcraft test conditions. For high-ambient applications above 85 °C, derate current to approximately 475 mA (70% of rated) to maintain junction temperature below 125 °C. The molded body has a thermal resistance of approximately 220 °C/W to ambient, so additional PCB copper pour beneath the part can reduce operating temperature by 10-15 °C in thermally constrained designs.
Follow the Coilcraft recommended land pattern of 2.5 x 1.7 mm with two pads of 0.9 x 0.6 mm. Place the inductor directly over a continuous ground or quiet power plane to provide a low-impedance thermal path. Avoid routing high-current traces under the inductor body, as the magnetic field can induce currents in adjacent traces. Maintain at least 2 mm clearance from sensitive analog signal traces to prevent coupling from the inductor's residual field (typically <5% of unshielded at this distance).
Do not use the PFL2015-682MEC in continuous-operation designs where peak current exceeds 680 mA - the molded construction does not provide user-replaceable thermal management. Verify the actual saturation behavior from the Coilcraft L vs I curve, as the 680 mA rating refers to RMS heating limit, not saturation limit (which is typically higher at 25 °C but drops with temperature). For 2 MHz+ switching frequencies, check the self-resonant frequency from the datasheet - operation above SRF causes the inductor to behave capacitively, degrading efficiency.
