It's also available in 5.0 Volt versions. At 2.0 mm maximum height (1.8 mm typical), 4810/4910 sets a new world standard for crystal oscillators. Model 4910 is the higher performance of the two — maximum rise and fall times are 7 nsec (vs. 10 nsec), and output drive is 16 mA (vs. 4 mA). Model 4810's output frequency runs from 1.8432 MHz to 50 MHz; 4910 outputs up to 67 MHz. "What's more, we've been able to eliminate the heat associated with conventional glass-sealing," explains Raltron's President Alexander Wolloch. "Other devices are typically subjected to high temperatures — 400 deg C and more. But our new 4810/4910 family never gets above 100 degrees C. This helps assure high stability and long term reliability." Raltron's new Model CO-4810/4910 family of integrated crystal oscillators priced at $3.00 each in 10,000s quantity Delivery is quoted at 8 weeks ARO. Established in 1983, Raltron Electronics Corp offers a wide variety of time, frequency and resistive components for computer logic, radio, telecommunications and consumer electronics, including quartz crystals and oscillators, filters, ceramic resonators and resistive networks for through-hole and SMT uses.
