Packaging Tape & reel (12mm): 7" reel, 650 pieces max.;
13" reel, 2500 pieces max.
Made In the U.S.A.
Mechanical Configuration Inductors are encapsulated in a Surface Mount
package, using an epoxy molded case. Leads are pretinned. A high resistivity
ferrite core allows for high inductance with low DC resistance.
