HS-420 Series
Description
The HS-420 Series of quartz crystal oscillators are resistance welded in an all metal package, offering RFI
shielding, and are designed to survive standard wave soldering operations without damage. Insulated
standoffs to enhance board cleaning are standard.
Features
• Wide frequency range–244.0Hz to 625.0kHz
• User specified tolerance available
• Will withstand vapor phase temperatures of 253°C
for 4 minutes maximum
• Space-saving alternative to discrete component
oscillators
• High shock resistance, to 3000g
• All metal, resistance weld, hermetically sealed
package
• Capable of driving 3TTL Loads
• Low Jitter
• High Q Crystal actively tuned oscillator circuit
• Power supply decoupling internal
• No internal PLL avoids cascading PLL problems
• Gold plated leads - Solder dipped leads available
upon request
• RoHS Compliant, Lead Free Construction
(unless solder dipped leads are supplied)
