Features |
| |
|
|
| • |
Superior to RK73 series chip resistors in surge withstanding voltage and pulse withstanding voltage. |
| • |
SG73S (for surge) and SG73P (for pulse) are able to select resistance tolerance from  0.5%. |
| • |
Suitable for both reflow and flow solderings. |
| • |
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. |
