CN-KRT
anti sulfuration chip networks
(convex termination)
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 to mount
•
Easy soldering fillet inspection
•
Suitable for an image recognition mounter due to square
corner design
•
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.
