radial metal film leaded resistors
EU
features
• Lead frame construction
• High density assembly and excellent self-standing strength
• Marking: Blue body color with color dot marking
for resistance and tolerance values
• Products with lead-free terminations meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
