ILSI America offers crystals matching Raltron crystals in price and performance, including both industry standards HC49US, HC49USM leaded devices, as well as, ultra small surface mount ceramic packages, both 2 pad and 4 pad designs. Our crystals are also equivalent to the Pb free Raltron crystals. We achieve price parity by manufacturing our quartz crystals on high volume lines in our China facilities, which are certified to ISO 9002 standards. We also can design crystals to meet custom specifications of Raltron crystals for either the fundamental or overtone resonant modes. In addition to Raltron crystals, we have Raltron equivalent oscillators and ceramic resonators.
