Jastech EMC Consulting, LLC

Mission and Services

• Jastech-EMC Consulting LLC core competency is our system engineering approach to EMC compliance, design, and training.

Systems Engineering Approach to EMC

• Services we offer includes filter designs, product reviews, EMC test plans and EMC training seminars tailored to customer products and industry requirements.

• Our area of expertise includes new product designs and product retrofits that require EMC regulatory compliance or functional needs for:
  • All types of motors (AC or DC, brushed commutated or electrically commutated)
  • Printed circuit boards
  • Connectors
  • Integrated circuits
  • Component evaluation and characterization
  • Complex electro-mechanical assemblies


• We have INARTE certified ESD and EMC engineers with 60+ years of specialized EMC experience in automotive, military, consumer and industrial markets.
