Leveraging advanced ferrite, powdered iron, and winding technologies, TDK’s inductors cover a comprehensive range of form factors and specifications, tailored to the rigorous demands of automotive electrification, industrial automation, 5G telecommunications, consumer electronics, and renewable energy systems. By integrating TDK inductors, engineers can optimize system efficiency, reduce energy loss, and ensure compliance with global industry standards.

Core Product Series of TDK Inductors (Coils)

TDK’s inductor lineup spans specialized series for power, high-frequency, EMI suppression, and industry-specific applications, each optimized for key performance metrics:

1. Power Inductors (for DC-DC Conversion)

Flagship series designed for high-efficiency power conversion in automotive, industrial, and consumer electronics. The TDK EPCOS B82472 series (power inductors) features inductance ranges from 0.1µH–1000µH, current handling up to 100A (saturation current), and ultra-low DCR (down to 0.3mΩ). Automotive-grade variants (AEC-Q200 compliant) like the B82477 series withstand extreme temperatures (-40°C–150°C) and vibration, ideal for EV powertrains, battery management systems (BMS), and on-board chargers (OBC). Miniature surface-mount (SMD) power inductors (e.g.,B82593 series) offer compact footprints (2.0mm×1.6mm) for consumer electronics (smartphones, laptops) and IoT devices.

2. High-Frequency RF Coils & Inductors

Optimized for 5G, Wi-Fi 6/6E, and wireless communication applications, with stable inductance up to 10GHz. The TDK MLK series (high-frequency chip inductors) offers inductance from 0.1nH–10µH, Q-factor ≥60 (at 1GHz), and low parasitic capacitance, suitable for 5G base stations, RF front-end modules, and satellite communication devices. Air-core RF coils (e.g., B82150 series) provide high linearity and low loss, ideal for high-precision wireless signal processing.

3. EMI Suppression Inductors & Common-Mode Chokes

Specialized solutions for reducing electromagnetic interference in power lines and signal circuits. The TDK EPCOS B82720 series (common-mode chokes) supports voltage ratings up to 600V AC/DC, current up to 50A, and offers high attenuation of common-mode noise (≥40dB at 100MHz). Suitable for industrial motor drives, renewable energy inverters, and medical devices (compliant with IEC 60601). Differential-mode chokes (e.g., B82730 series) suppress differential noise in power supplies and data lines.

4. Automotive-Specific Inductors

Customized for vehicle electrification and ADAS (Advanced Driver Assistance Systems). This includes power inductors for EV DC-DC converters (ISO 26262 ASIL B compliant), common-mode chokes for in-vehicle Ethernet (compliant with IEEE 802.3bw), and RF coils for V2X (Vehicle-to-Everything) communication. All automotive inductors meet AEC-Q200, automotive EMC (CISPR 25), and vibration (ISO 16750) standards, ensuring reliability in harsh vehicle environments.

5. Industrial & Renewable Energy Inductors

Heavy-duty inductors for industrial automation and renewable energy systems. The B82446 series (industrial power inductors) features IP67 protection, inductance up to 10mH, and current handling up to 80A, suitable for factory robotics, motor drives, and solar/wind inverters. High-voltage inductors (up to 1500V DC) support grid-connected renewable energy conversion, with stable performance under dynamic load conditions.

Key Features of TDK Inductors (Coils)

TDK’s inductors stand out for their technical superiority, addressing critical pain points in power and signal processing applications:

• High Current Handling & Low DCR：Saturation current up to 100A and DCR as low as 0.3mΩ minimize power loss, improving system efficiency (up to 98% for DC-DC converters).

• Stable Inductance Over Temperature：Advanced core materials (ferrite, powdered iron) ensure inductance drift ≤±10% across -40°C–150°C, maintaining performance in extreme environments.

• EMI Suppression Capability：Common-mode and differential-mode chokes offer high noise attenuation, complying with global EMC standards (IEC 61000-4-2, CISPR 22).

• Industry Compliance & Reliability：AEC-Q200 (automotive), ISO 26262 (functional safety), IEC 60601 (medical), and UL/cUL certifications ensure compatibility with sector-specific regulations. Long operational lifespan (≥10,000 hours at 105°C) reduces maintenance costs.

• Versatile Form Factors：Available in surface-mount (SMD), through-hole, and custom winding designs, with footprints from 2.0mm×1.6mm (miniature) to 30mm×30mm (industrial), supporting diverse PCB design requirements.

Application Fields

TDK Inductors (Coils) are integral to power and signal processing systems across high-demand sectors:

• Automotive & Transportation：EV powertrains, BMS, OBC, ADAS sensors, in-vehicle infotainment, and V2X communication systems.

• Industrial Automation：Factory robotics, motor drives, PLCs (Programmable Logic Controllers), industrial power supplies, and smart manufacturing IoT devices.

• Telecommunications & 5G：5G base stations, RF front-end modules, network routers, data center servers, and satellite communication devices.

• Consumer Electronics：Smartphones, laptops, wearables (smartwatches, earbuds), gaming consoles, and home appliances (air conditioners, refrigerators).

• Renewable Energy：Solar/wind inverters, energy storage systems, and grid-connected power distribution modules.

Source Genuine TDK Inductors (Coils) via Authorized Distributors

To guarantee inductance stability, current handling performance, and system reliability, sourcing genuine TDK Inductors (Coils) from official authorized distributors is critical. Counterfeit inductors often have inconsistent inductance, high DCR, and poor temperature resistance—risking system overheating, efficiency loss, and catastrophic failure, especially in automotive and medical applications.
