features
• Resistors meeting MIL-R-26E (U and
V characteristics) and surface temperature
(hot spot) 350°C max.
• Resistors with a wide range of 0.1Ω ~ 62kΩ,
covering applications from precision to power
• RW N type resistors are non-inductive wound
and can be used in high frequency applications.
• Marking: Black body color with alpha-numeric marking
• Products with lead-free terminations meet EU RoHS
and China RoHS requirements
