Temperature-Compensated 32 kHz Oscillators from Seiko Instruments

Do you need a solution that is more accurate than traditional quartz oscillators?

The SH-32R and SN-20S temperature compensated 32 kHz oscillators from Seiko Instruments are calibrated to an impressive +/-3 ppm at 25 °C. These high performance oscillators are the perfect answer to applications where conventional 32 kHz crystal oscillators reach their limits.

Why you should opt for these oscillator solutions:

• Increased precision:
  Eliminate the inaccuracies that can reach +/-37ppm with uncalibrated crystal oscillators - that's almost 98 seconds per month!
  
  
• Robust for all environments:
  Specially designed to compensate for temperature drift - this is especially important for outdoor applications where conditions are extreme.
  
  
• Easy integration:
  With the plug-n-play feature, you can easily install the oscillator without having to design an oscillation circuit. Fewer components are required on the printed circuit board (PCB), which simplifies the design considerably.

Two product variants for every need:

• SH-32R:
  A front runner for temperature compensated precision.
  Ideal for critical applications where every second counts.
  
  
• SN-20S:
  An affordable option that is extremely power efficient.
  Ideally suited for projects where temperature compensation plays a subordinate role.

Whether for improving the accuracy of real-time clocks in microcontrollers or for precise time measurement in your electronics application:
Seiko Instruments offers you one of the most advanced solutions on the market.
