Features
|
| |
|
|
|
| • |
Transponder coil that is arranged it’s electrode in the long side of the part, and is covered with molding resin. |
 |
| • |
Excellent high Q and high sensitivity, because neither the electrode nor the land pattern disturb the coil flux. |
| • |
Strong to vibration, shock and substrate bend test by 4 electrode terminals structure and the molded resin. |
| • |
Small inductance change to environmental temperature change. |
| • |
Suitable for reflow soldering. |
| • |
Products meets EU-RoHS requirements. |
|
