features
• Miniature construction endurable to high voltage
and high power
• Resistors excellent in anti-surge characteristics
• Wide resistance range of 0.5MΩ - 10GΩ and small T.C.R.
• Marking: Brown body color with alpha/numeric marking
• 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.
