UNI-PAC™ 0.4C
Low Cost, Low Profile
Power Inductors (Surface Mount)
Description
RoHS
2002/95/EC
• Miniature size and rugged construction
• Designed for high shock environments
• Suited for IR and vapor reflow solder
• Frequency range 1kHz to 2MHz
• Ferrite core material
Applications
• Computer, pager and battery powered equipment
Environmental Data
• Storage temperature range: -40°C to +125°C
• Operating ambient temperature range: -40°C to +85°C
range is application specific. Temperature rise is
approximately 40°C at rated RMS current. Maximum
operating temperature is 125°C including ambient.
• Solder reflow temperature: +260°C max. for 10 seconds
max.
