1. The filters are mountable by automatic placers.
2. The filters can be reflow soldered and withstand
washing.
(in mm)
3. They are slim, at only 4.0mm maximum thickness,
and have a small mounting area (7.5x6.0mm)
enabling flexible PCB design.
4. The bandwidth ranges from A to E.
5. Operating temperature range : -20 to +80 (degree C)
Storage temperature range: -40 to +85 (degree C)
