The 32.768 kHz clock crystal in a 3.2x1.5mm/2pad ceramic housing is our most affordable 32.768 kHz MINI crystal ever!
The 3.2x1.5mm/2pad SMD crystals of the M3215RR series feature our highly innovative LRT crystal resonators (LOW ESR Resonator Design) with a maximum resistance of 50 kOhm. Each of our products is 100% tested, so we can offer outstanding product quality, maximum lifetime and a very reliable partnership with competent support. Based on our own mold, we can also supply the SMD clock crystals of the M3215RR series at very competitive prices.
We therefore do not necessarily recommend our customers to use 32,768 kHz crystals in smaller housings with the dimensions 2.0x1.2mm or 1.6x1.2mm. This is because these smaller 32.768kHz crystals have a significantly higher resistance (90kOhm), which can lead to massive oscillation problems in many 32.768kHz oscillator stages. In addition, these small clock crystals are significantly more expensive than the 3.2x1.5mm/2pad 50 kOhm LOW ESR crystal of the M3215RR series.
Even if the requirement for miniaturization of the circuit boards is often very high, it is extremely worthwhile to stay with the 32.768kHz crystal in the 3.2x1.5mm/2pad ceramic housing. Also in automotive applications, for which there are also corresponding M3215RR solutions.
M3215RR 32.768 kHz crystals are available with load capacities of 4, 6, 7, 9 or 12.5 pF. Normally from stock.

Why is PETERMANN-TECHNIK the right partner for vibrating quartz crystals?
PETERMANN-TECHNIK GmbH is the right partner for oscillating crystals because we not only supply the component, but also support customers in the correct selection, design and integration into the respective circuit. A quartz crystal is a key frequency-determining component. Its quality, its resistance, its load capacity, its frequency stability and its behaviour in the real circuit directly influence the functional reliability of the end product.
Many electronic applications only function reliably if the crystal oscillator resonates reliably and operates stably over the long term. This applies to microcontroller circuits, wireless modules, smart meters, sensors, industrial electronics, automotive applications, medical technology and many other devices. This is why choosing the right crystal is not just a purchasing decision, but an important technical design decision.
PETERMANN-TECHNIK offers customers a wide range of SMD oscillating crystals, THT crystals, LRT oscillating crystals and crystal oscillators. With our technical advice, our product configurators, our cross-reference function and our design-in service, we help developers to quickly and reliably find the right oscillating crystal for a reliable electronics solution.
