EMI/EMC Filter

EMC Filter is an electronic component that prevents malfunction and damage to other devices by removing unnecessary electromagnetic waves generated inside devices such as motors, electronic control devices, power supplies, microprocessors, and inverters. Furthermore, EMC Filter is expanding its use areas such as electric vehicle chargers, renewable energy, data centers, and automation equipment. EMC regulations are being established to efficiently suppress electromagnetic waves generated from electronic devices in power systems. Accordingly, The Dongil Technology obtained major national standard certifications, has optimized price competitiveness, and can develop customized products for customers. 

Main use and Related Business

There are automation facilities, electric vehicle chargers, machine tools, solar power, and ESS facility companies that require electromagnetic wave certification. In addition, there are manufacturers of SMPS power supplies, communication networks, medical devices, and home appliances, which are all companies that require electromagnetic certification.
