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
•Easy soldering fillet inspection
•Suitable for an image recognition mounter due to square
corner design
•Marking: Black body color
•Products with lead-free termination meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
