Series 50 Surface Mount
Power Inductors
Manufactured to meet the environmental requirements of MIL-T-27, these power inductors cover an
inductance range of 1.0 to 1000 µH. Standard inductance tolerances are listed, other tolerances are
available. The standard termination finish is tin-lead solder, plated over hard copper, and a gold plated
finish is also available. Two termination options are provided, with tabs and without, to allow different
mounting methods. Each unit has two windings that are connected in series or parallel, by the user, to
yield the listed characteristics.
Key characteristics:
Low profile, transfer molded, surface mount package
Four sizes; leaded and leadless configurations
Ideal for automatic insertion
Weight of 0.5 to 5 grams
Meets MIL-T-27, Grade 5, Class S
Operating temperature range: -55°C to 130°C
Maximum temperature rise (@90°C): 30°C
Part Numbering System:
50 - 005 - 20 - T
