features
•
Excellent anti-sulfuration characteristic
due to using high sulfuration-proof inner
top electrode material
•
More advancement in the mounting density than
individual chip resistors
•
Mounting cost reduction by decreasing the number
of parts mounting times
•
Higher self-alignment effect in reflow-soldering process
•
Suitable for an image recognition mounter due to
square corner design
•
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.
