Dongguan Jansum Electronics Co., Ltd. (brand: JASN), as a national high-tech enterprise with 19 years of deep experience in the field of magnetic devices, has always focused on the dual main businesses of BMS signal isolation transformers and network transformers. It targets the automotive, industrial, and communication markets. Leveraging its full-chain technology strength, efficient delivery capabilities, and cost-effective solutions, it has become a benchmark in the second tier of domestic BMS transformers and a leading supplier in the energy storage and 400V vehicle-mounted fields. It continues to provide reliable signal isolation and transmission solutions for the new energy vehicle, energy storage, industrial control, and network communication industries.
1. Solid qualifications and production capacity lay a solid foundation for domestic substitution
Jianxu Electronics was established in Changping, Dongguan in 2007. It holds full system certifications such as IATF16949, ISO9001, RoHS, and UL. Its core products have all passed AEC-Q200 automotive-grade certification, fully meeting the stringent standards for automotive and industrial applications. The company‘s monthly production capacity for BMS transformers stands at 8 million to 12 million units, which is on par with the top domestic tier and significantly exceeds the delivery efficiency of international brands. Customized delivery times are only 2 to 4 weeks, a substantial reduction compared to the 16 to 20 weeks required by international brands. The price is only 1/2 to 2/3 of that of international brands, and the gross profit margin remains stable at 25% to 32%. With its "fast delivery, high cost-effectiveness, and strong customization capabilities," it has become the preferred choice for domestic substitution.
II. BMS Signal Transformer: Automotive-grade performance, adaptable to full-scenario new energy requirements
As the core business of the company, Jianxu BMS signal isolation transformers precisely meet the signal isolation and anti-interference requirements of new energy vehicles and energy storage systems, with core parameters fully benchmarked against the top industry standards:
Isolation voltage: 3750VAC–6000VDC, covering mainstream 400V platforms and adapting to 800V high-voltage platform iterations;
Operating temperature range: -40℃ to +125℃, meeting automotive-grade stable operation across the full temperature range;
Coupling capacitance: ≤12pF, ensuring CMTI anti-interference capability and ensuring zero packet loss and high reliability in BMS communication;
Product form: Single/dual/multi-channel patch type, perfectly compatible with mainstream BMS chips such as LTC6815, MC33771, and BQ79616. Supports basic insulation/enhanced insulation dual options, with priority given to the enhanced insulation solution for the 800V high-voltage platform.
Currently, the product has been fully adapted to 400V new energy vehicle-mounted systems and has achieved mass production and supply. The 800V high-voltage platform is undergoing accelerated certification and iteration, with small batches of samples being sent for testing. At the same time, it covers scenarios such as household storage/commercial and industrial energy storage, industrial control/photovoltaic BMS, etc., and can directly replace international brands such as Würth, Bourns, and TDK, offering significant cost-effective advantages.
III. Network magnetic devices: full-rate coverage, boosting the localization of communication equipment
Relying on the accumulated technology of magnetic devices, Jianxu has simultaneously entered the network transformer arena, creating a product matrix including 100M/Gigabit/2.5G/10G full-rate network transformers, POE filter transformers, common mode inductors, and other products. These products are widely used in switches, routers, industrial gateways, security systems, industrial control motherboards, and other devices. The mid-to-high-end network transformers have achieved mass production and can stably replace Taiwanese and Japanese brands, providing key support for the localization of communication equipment.
IV. Core Advantages: One-stop Support, Empowering Customers with Efficient Model Selection
Complete vehicle certification: AEC-Q200 mass production implementation, IATF16949 system support, quality benchmarking against international standards;
Delivery and customization advantages: short delivery time, rapid customization, and flexible response to customer iterative needs;
Dual-main business synergy: BMS + network magnetic components one-stop supporting, reducing customer selection and supply chain costs;
Market depth coverage: Main supplier of 400V vehicle-mounted and energy storage systems, with comprehensive penetration in industrial/communication fields.
V. Looking Ahead: Pushing the Boundaries of High-End Technology, Leading the Upgrade of Domestic Magnetic Devices
In response to the rapid development of the new energy and communication industries, Jianxu Electronics will continue to focus on three major directions: 800V high-voltage platform, high-end industrial BMS, and 10G+ high-speed network transformers. It will accelerate technological iteration and market expansion, continuously enhancing its brand influence and market share in specific segments. In the future, the company will position itself as "automotive-grade quality, pioneer in domestic substitution," and work with global customers to contribute core strength to the safe, efficient, and domestically-developed development of the new energy and communication industries.
