60 Series
Two Terminal Metal Element
Current Sense
These non-inductive, 3-piece welded element resis-
tors offer a reliable low-cost alternative to conven-
tional current sense products. With resistance values
as low as 0.005Ω, and wattages from 0.1w to 3w,
the 60 Series offers a wide variety of design choices.
F e at u r e S
• Low inductance
• Low cost
• Wirewound performance
• Flameproof
