As a global leader in passive electronic components and power conversion solutions, TDK delivers high-performance Transformers engineered for ultra-high efficiency, stable power transmission, and robust reliability in critical power conversion scenarios. Leveraging advanced core materials (ferrite, amorphous alloy), precision winding technology, and EMI (Electromagnetic Interference) shielding design, TDK’s transformers cover a comprehensive range of specifications—from miniature surface-mount variants for consumer electronics to heavy-duty industrial-grade models for renewable energy systems. Tailored to meet the rigorous demands of automotive electrification, industrial automation, 5G telecommunications, and medical devices, TDK transformers ensure efficient power conversion, electrical isolation, and compliance with global industry standards.

Core Product Series of TDK Transformers

TDK’s transformer lineup spans specialized series for power conversion, isolation, high-frequency, and industry-specific applications, each optimized for key performance metrics:

1. Power Transformers (for AC-DC/DC-DC Conversion)

Flagship series designed for efficient power conversion in industrial, automotive, and consumer electronics. The TDK EPCOS B82735 series (power transformers) supports input voltage ranges from 110V–480V AC, output power up to 5000VA, and conversion efficiency ≥95%, ideal for industrial power supplies, UPS systems, and renewable energy inverters. Automotive-grade variants (AEC-Q200 compliant) like the B82736 series withstand extreme temperatures (-40°C–150°C) and vibration, tailored for EV on-board chargers (OBC), DC-DC converters, and battery management systems (BMS). Miniature surface-mount (SMD) power transformers (e.g., B82738 series) offer compact footprints (8mm×6mm) for smartphones, wearables, and IoT devices, supporting low-power DC-DC conversion.

2. Isolation Transformers

Specialized for electrical isolation and safety protection in medical, industrial, and consumer applications. TheTDK EPCOS B82740 series (isolation transformers) provides isolation voltage up to 10kV AC, insulation resistance ≥100MΩ, and compliance with IEC 61558 and UL 60601 (medical grade). Medical-grade variants are ideal for portable diagnostic equipment, hospital monitoring systems, and implantable device power supplies, ensuring patient and equipment safety. Industrial isolation transformers (e.g., B82741 series) offer resistance to moisture and chemical corrosion, suitable for harsh factory environments and process control systems.

3. High-Frequency Transformers (for 5G & RF Applications)

Optimized for high-frequency power conversion and signal transmission in 5G, Wi-Fi 6/6E, and telecommunications systems. The TDK B82800 series (high-frequency transformers) operates at frequencies up to 1MHz, with low insertion loss (≤0.5dB) and stable impedance, suitable for 5G base stations, RF front-end modules, and satellite communication devices. Miniature high-frequency transformers (e.g., B82801 series) support surface-mount assembly, reducing PCB space for compact 5G CPE (Customer Premises Equipment) and industrial IoT gateways.

4. Automotive-Specific Transformers

Customized for vehicle electrification and ADAS (Advanced Driver Assistance Systems) requirements. This includes planar transformers for EV powertrains (supporting 400V–800V high-voltage platforms), isolation transformers for in-vehicle Ethernet (compliant with IEEE 802.3bw), and high-frequency transformers for V2X (Vehicle-to-Everything) communication. All automotive transformers meet AEC-Q200, automotive EMC (CISPR 25), and functional safety standards (ISO 26262 ASIL B), ensuring reliability in harsh vehicle environments.

5. Industrial & Renewable Energy Transformers

Heavy-duty models for industrial automation and renewable energy systems. The B82739 series (industrial transformers) features IP67 protection, output power up to 10kVA, and compatibility with 3-phase AC power systems, suitable for factory robotics, motor drives, and solar/wind inverters. Amorphous alloy core transformers (e.g.,B82742 series) offer ultra-low no-load loss (≤15W), ideal for large-scale energy storage systems and grid-connected power distribution.

Key Features of TDK Transformers

TDK’s transformers stand out for their technical superiority, addressing critical pain points in power conversion and electrical isolation applications:

• Ultra-High Conversion Efficiency：Conversion efficiency up to 98% for power transformers, minimizing energy loss and reducing system operating costs—critical for renewable energy and industrial 24/7 operations.

• Broad Temperature & Environmental Adaptability：Operates in extreme temperature ranges (-40°C–150°C), resists vibration (up to 50g peak) and moisture (IP67 protection for industrial models), adapting to automotive, industrial, and outdoor environments.

• Strong EMI Shielding：Integrated EMI shielding design (metal cans, ferrite cores) reduces electromagnetic radiation, complying with global EMC standards (IEC 61000-4-2, CISPR 22/25) and protecting sensitive electronic components.

• Global Industry Compliance：AEC-Q200 (automotive), ISO 61558 (power transformers), UL 60601 (medical), and RoHS/REACH certifications ensure compatibility with sector-specific regulations and global market access.

• Versatile Form Factors & Easy Integration：Available in surface-mount (SMD), through-hole, and planar designs, with footprints from 8mm×6mm (miniature) to 200mm×150mm (industrial), supporting diverse PCB and system integration requirements.

Application Fields

TDK Transformers are integral to power conversion and electrical isolation systems across high-demand sectors:

• Automotive & Transportation：EV on-board chargers (OBC), DC-DC converters, BMS, in-vehicle infotainment, and ADAS power modules.

• Industrial Automation：Factory robotics, motor drives, PLCs (Programmable Logic Controllers), industrial power supplies, and process control systems.

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

• Telecommunications & 5G：5G base stations, RF front-end modules, network routers, and data center power systems.

• Medical Devices：Portable diagnostic equipment (ultrasound, blood pressure monitors), hospital monitoring systems, and implantable medical device power supplies.

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

Source Genuine TDK Transformers via Authorized Distributors

To guarantee conversion efficiency, isolation performance, and system reliability, sourcing genuine TDK Transformers from official authorized distributors is critical. Counterfeit transformers often have inconsistent power transmission, poor heat dissipation, and non-compliant insulation—risking system overheating, electrical short circuits, and safety hazards, especially in automotive and medical applications.
