UNI-PAC™
Power Inductors
(Surface Mount)
Description
RoHS
2002/95/EC
• Miniature surface mount design
• Inductance range from 0.470uH to 1000uH
• Current range from 19.2 to .47 Amps
• Maximum power density
• Ideal for applications requiring low inductance and high
current in a miniature package
• Modified standard products are available
• Protective case eliminates core breakage
• Meets UL 94V-0 flammability standard
• Ferrite core material
Applications
• DC-DC converters on board level and industrial
products
Packaging
Environmental Data
