Ohmite HS250F20R Aluminum housed axial terminal wirewound, industrial/commercial grade Datasheet

The HS/HSN Series offers
greater power capacity (100
and 250 watts) in the same
design format as Ohmite’s 89
Series.
HS/HSN Series maintains
the same construction, materials, and manufacturing techniques as the 89 Series. As
a made-to-order product, it is
recommended for higher volume applications.
Features
• Standard winding (Model HS)
• Non-inductive winding (Model
HSN)
• Molded construction for total
environmental protection
• Complete welded construction
• Mounts on chassis to utilize
heat-sink effect
• High stability at conventional
power ratings
• Flat marking surface for easy
identification
• RoHS compliant; add “E” suffix
to part number to specify.
