Micrometals has been a leading global manufacturer of inductor cores for over 65 years. Founded in Southern California in 1951, Micrometals maintains their headquarters and primary manufacturing facility in Anaheim, California, and have additional manufacturing facilities in China. Micrometals cores are found in thousands of applications worldwide, from cutting-edge flat-screen TVs and power conditioning systems to electric vehicles and the engines powering offshore oil rigs. Micrometals’ cores have been the gold standard in the industry since their inception, and Micrometals continues to lead in quality and innovation.
Micrometals’ 200C and Alloy powder core offerings are well-suited for high-temperature applications. Micrometals’ 200C materials do not exhibit thermal aging up to 200°C, while Micrometals’ Alloy offerings do not experience thermal aging effects. Unlike ferrites, powdered iron and alloys have higher and much more stable saturation flux density that does not decrease at elevated temperatures. Typical applications for our inductive components include:
- Flyback Transformer – Ignition Coils
- DC Inductor – 12V to 48V DC-DC Battery Converter
- DC Inductor – 12V-5V/1.2V DC-DC Converters for lighting, vehicle sensing and safety systems, and power management
- AC Inductor – DC-AC Inverter for motor drive and regenerative braking, Output Filter
- AC Inductor – AC-DC Onboard Charger, Differential Mode Input Filter
- PFC Inductor – AC-DC Onboard Charger
Typical applications for inductive components within internal combustion and mild hybrid engines include ignition coils, 12V to 48V converters, DC-DC converters for lighting, vehicle sensing and safety systems, and power management. One of the most unique aspects of Micrometals’ distributed gap powder cores is their versatility, allowing them to be pressed into complex shapes to optimize EMI shielding, space constraints, or weight.
