SURFCOIL® SMT Chip Inductors

(This bulletin is also available as a pdf file.)

Features:

• High Q
• High self-resonant frequency including nonmagnetic models in microwave range
• Shielded series use ferrite filled encapsulation to reduce external magnetic coupling
• Low DC resistance
• Carrier and reel packaging is standard
• Seven case sizes

Specifications:

• Inductance & Q, etc. - See tables
• Temperature range -20°C to +85°C, except GLY, GLYC, GLTZ, GLZ and GLZP Models are -40°C to +85°C
  • Change of L = ± 10% max, except GLX, GLY, GLYC, GLTZ, GLZ and GLZP Models are ± 5%
    
  • Change of Q = ± 20% max, except GLY, GLYC, GLTZ, GLZ and GLZP Models are ± 25%
• Rated Current: See tables. Current rating is determined by either or both of the following conditions:
  1. Self heating raises SURFCOIL temperature 20°C
  2. Inductance value reduced by 10% from saturation effect

   Mechanical

• Suitable for wave flow soldering, and infrared and vapor phase reflow. (Typically over 90% coverage)
• Withstands soldering temperatures without damage
• Fully encapsulated and thermally cycled for stability and highest reliability

(View applies to molded bobbin wound types)

Encapsulation: Epoxy resin all series; GLC, GLD and GLW have ferrite filler for closed magnetic circuit. Core: Ferrite (except high frequency GLA and GLU series, which are nonmagnetic) Coil: Polyurethane enameled copper wire Terminal: Phosphor-Bronze solder plated
