WORLD'S THINNEST SURFACE MOUNT
OSCILLATOR RUNS ON 3.3 VOLTS.

Miami FL, May 17, 1999 — Raltron Electronics Corp here announces a revolutionary new fully integrated surface
mount quartz crystal oscillator that operates on 3.3 V. is just 2.0 mm thin, and uses no damaging heat in its
manufacturing process
New model CO-4810/4910 is a super-miniature SMT clock oscillator for today's smallest computers and
peripherals. 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.
