Features |
| |
|
|
| • |
Excellent anti-sulfuration characteristic due to using high sulfuration-proof inner top electrode material. |
| • |
Superior to RK73 series chip resistors in pulse withstanding voltage. |
| • |
Suitable for both flow and reflow solderings. |
| • |
This products meet EU-RoHS requirements. EU-RoHS regulation is not intended for Pb-glass contained in electrode, resistor element and glass. |
