Inductors
Epoxy Conformal Coated
Uniform Roll Coated
FEATURES
• Flame-retardant coating
• Color band identification
• Excellent environmental characteristics
• Uniform coating is excellent for automatic RoHS
insertion
COMPLIANT
• Comparable in quality to molded chokes at a lower price
• Epoxy coating is more durable than lacquer coated
models, yet is priced comparably
