Chip Attenuator PAT0510S |
|
YDS's thin film fixed chip attenuator consists of high precision thin films and is very small with high performance. It has the attenuation circuit in an element, especially PAT0510s is much smaller. Also, the form of wrap-round electrode as well as chip resistors, makes it much easier to mount, and available when the strength after mounting is needed. |
