Engineered for immediate integration into consumer devices, smart cabins, and industrial hardware. Certified pathways compatible with ANATEL regulations.
An authoritative analysis of regulatory requirements, application paradigms, and industrial growth in Latin America's largest economy.
The demand for high-efficiency wireless power transfer (WPT) systems in the Brazilian market is undergoing exponential growth. Driven by the digitization of public infrastructure, automotive design evolution in regions like São Paulo and Minas Gerais, and the continuous expansion of the Manaus Free Trade Zone (Zona Franca de Manaus), local manufacturers require robust, high-grade semiconductor integrations. However, implementing wireless charging modules in Brazil is not without unique regional complexities.
Unlike less-regulated markets, Brazil requires strict conformity to electrical safety standards and electromagnetic compatibility (EMC). Wireless power modules must comply with the National Telecommunications Agency (ANATEL) guidelines, specifically addressing restricted radiation radio communication devices under Act 14448. Without precise circuit topologies, low-resistance MOSFET switching, and microcontrollers optimized for thermal stability, obtaining local certification can be a prolonged, capital-intensive process.
As a leading developer and distributor, OLUKEY INDUSTRY CO., LIMITED, along with our proprietary line of WINSOK MOSFETs and Cmsemicon MCUs, bridges this gap. We supply verified, industry-ready PCBA solution developments that minimize electromagnetic interference (EMI) and power loss. This allows Brazilian hardware engineers to confidently meet ANATEL standards while accelerating time-to-market.
Thermal mitigation is critical for wireless charging devices operating in high ambient temperature regions like Northern and Northeastern Brazil. Under tropical operating conditions, standard silicon MOSFETs experience thermal runaway due to increased drain-source on-resistance (RDS(on)). Our WINSOK MOSFET ranges (ranging from 15V to 650V in advanced packages like DFN5X6-8L and DFN3X3-8) are engineered with exceptionally low gate charge (Qg) and thermal resistances, ensuring they operate well within safety margins even at 85°C ambient temperatures.
Using optimized WINSOK N-channel MOSFET configurations in active clamp forward converters, our modules achieve industry-leading efficiency levels, reducing thermal dissipation under continuous high-power loads.
Where high-performance wireless power transfer meets Brazilian commercial, automotive, and industrial infrastructure.
Brazil is the largest automotive producer in South America. Modern vehicle models built in São Bernardo do Campo and Porto Real require integrated Qi-standard wireless charging compartments. Using low-to-medium voltage WINSOK MOSFETs (e.g., 30V to 40V N-Channel MOSFETs with DFN5X6-8L packages), automotive Tier-1 suppliers can build ultra-compact, high-efficiency transmitters. These components are designed to withstand vehicle battery load-dump transitions and high voltage spikes.
In agribusiness hubs like Mato Grosso and Paraná, IoT sensors and data collection systems are subject to harsh environmental conditions, including mud, humidity, and chemical exposure. Sealed enclosures with physical ports often fail due to corrosion. Wireless power charging solutions offer a reliable alternative, enabling hermetically sealed industrial devices to recharge inductively. Our robust MCU solutions ensure stable power delivery even through thick plastic or glass housings.
For Brazilian manufacturers importing components or modules, complying with the following international standards ensures smoother ANATEL approval pathways:
We provide full layout reference files and BOM transparency. By selecting OLUKEY's highly integrated controllers and low-EMI WINSOK MOSFETs, engineers can significantly reduce harmonics, passing ANATEL's strict emissions testing on the first run.
Hong Kong Olukey Industry Co., Limited — Your strategic semiconductor and PCBA solution partner.
HONGKONG OLUKEY INDUSTRY CO., LIMITED is a premier global solution provider focusing on overall electronic product component strategies. Our core business spans three primary product lines:
Olukey Industry products are widely used in critical sectors including automotive electronics, aerospace/military applications, smart industrial control systems, new energy solutions, smart medical devices, 5G infrastructure, IoT networks, smart homes, and diverse consumer electronics. Based in the Asia-Pacific market and leveraging strong partnerships with top global component factories, we deliver high-tech electronic components to manufacturers worldwide.
We combine the advantages of global component sourcing with local technical support. This allows us to offer optimized supply chain logistics, helping Brazilian importers mitigate high import duties and customs complexities.
How our technical strengths translate to lower R&D costs and superior manufacturing quality for Brazilian clients.
For decades, Olukey Industry has prioritized quality and client service. Through close cooperation with global high-tech enterprises and semiconductor foundries, we have developed a robust distribution network. For the Brazilian market, we deliver critical advantages that help streamline development processes:
In high-frequency resonant inductive charging circuits, switching losses can exceed conduction losses. By utilizing WINSOK's proprietary gate trench designs, our MOSFETs significantly lower gate-to-drain charge (Qgd). This enables faster transitions, less energy dissipation, and cooler operating temperatures during active power transmission.
Select WINSOK MOSFETs and control hardware optimized for high-power wireless transmitters, industrial converters, and automotive systems.
Managing local tariffs, customs processes, and quality standards for hardware components.
Importing electronic components into Brazil involves navigating complex regulatory requirements, including high import tariffs (IPI, ICMS, and PIS/COFINS taxes). This complex tax environment, often referred to as the "Custo Brasil", can significantly impact supply chain overheads if logistics are mismanaged. Additionally, shipments held in customs (Receita Federal) due to incomplete compliance documents can cause critical production delays.
OLUKEY INDUSTRY simplifies these import processes for Brazilian OEMs, automotive manufacturers, and system integrators. We support flexible shipping strategies, offering complete product documentation, HS code alignment, and packaging that meets all import standards. Whether you are assembling locally in the Manaus Free Trade Zone (Zona Franca de Manaus) to access regional tax incentives, or shipping directly to southern industrial hubs, we help optimize your supply chain.
By purchasing complete wireless charging PCBA modules directly from our factories, you reduce the need to manage multiple component vendors. This consolidation lowers assembly complexity and reduces testing overheads, ensuring high-quality, factory-tested products arrive at your production lines in Brazil.
We supply trace documents, raw material certifications, and electrical testing certificates with each shipment. Our manufacturing partners adhere to ISO 9001 and ISO 14001 certification frameworks, ensuring reliable, repeatable performance across production runs.
