MQ Series  (160 k bytes)
5x7x1.2 mm - Surface Mount Crystals
 |
- RoHS compliant, Pb free product
- 1.2 mm height. Best suited for space constraint applications such as PCMCIA.
- Fine product due to our expertise in miniaturization.
- To minimize the EMI the whole package can be grounded
- through the kovar lid and the two non-crystal pads.
- ±10ppm tight tolerance is available for telecommunication applications.
