You can find more information on this in our TOP SELLER section or under the heading SEARCH FOR REFERENCE DESIGN (IC) FOR SMD QUARCIES.
We recommend the following SMD crystals for new developments:
32.768 kHz in 3.2x1.5mm/2pad ceramic housing with load capacitance of 4, 6, 7, 9 or 12.5 pF
- preferred, as they are the cheapest available
32.768 kHz in 2.0x1.2mm/2pad ceramic housing with load capacitance of 9 and 12.5pF
32.768 kHz in 1.6x1.0mm/2pad ceramic housing with load capacitance of 4, 6, 7, 9 or 12.5 pF
Check available stock quantities in our webshop or send us your enquiry directly from one of these items generated via the corresponding product generator.
Please note that we only recommend SMD crystals that can be sourced from us over a very long period of time, more than 10 years, with consistently excellent performance and quality.

Why is PETERMANN-TECHNIK the right partner for selecting the optimum kHz SMD oscillating quartz crystal?
PETERMANN-TECHNIK GmbH is the right partner if you are looking for a kHz SMD oscillating crystal and have no fixed specifications for the housing. In this case, it is not just the smallest design that counts, but the best combination of oscillation stability, power consumption, price, availability and long-term performance.
Particularly with 32,768 kHz clock crystals, the choice of housing can have a major influence on the behaviour of the oscillator circuit. Smaller designs are not automatically the better solution, as they can often have higher resistances. A lower resistance, on the other hand, supports a safer oscillation and can improve the functional reliability of the circuit. This is why PETERMANN-TECHNIK recommends the 32.768 kHz SMD clock crystal in the 3.2x1.5 mm/2 pad ceramic housing of the M3215RR series (50 kOhm max. as standard) as an economically attractive and technically safe solution for many applications.
With our experience, our LRT resonators, 100% testing and practical design-in support, we help customers to select the kHz SMD oscillating crystal that not only works today, but is also safely available and reliable for long-term use in series production.
