CHARACTERISTICS
Description:
Axial leaded conformal coated inductor
Applications:
Used in less harsh environments. Ideal for less
critical RFL/EMI applications.
Operating Temperature:
-40°C to +125°C
Inductance Tolerance:
±5%, ±10%, ±20%
Testing:
Inductance and Q are tested on an HP4285A at
specified frequency
Packaging:
Bulk pack or Tape & Reel, 5,000 parts per reel
Marking:
Parts are EIA color banded which indicates inductance
code and tolerance
Material:
Magnetic core (ferrite or iron) except for values 0.10 µH
to 0.82 µH (phenolic) treated with epoxy resin for protection and
longer reliability
Miscellaneous:
RoHS Compliant.
Additional Information:
Additional electrical & physical
information available upon request
Samples available. See website for ordering information.
