Features |
| |
|
|
| • |
Small size and light weight. |
| • |
Excellent heat resistance and weather
resistance are ensured by the use of metal glaze thick film. |
| • |
High stability and high reliability with
the triple-layer structure of electrode. |
| • |
Applicable to various kinds of automatic
mounters for taping, etc. |
| • |
Suitable for both flow and reflow 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. |
