SMD QUARZ 3.2x2.5mm is the low-cost MHz SMD oscillating crystal with excellent performance and durability
The MHz SMD crystal in a 3.2x2.5mm/4pad ceramic housing is a very inexpensive SMD crystal and has become the favorite of all applications in which inexpensive SMD clock generators with excellent performance, quality and durability are used, partly due to its LOW ESR resonator design. Thanks to the resistance-optimized resonator design, the SMD oscillating crystals in the SMD03025/4 series oscillating crystals oscillate very reliably and very quickly, even if the negative input resistances of the oscillator stages of the ICs and SOCs used are low or vary greatly. The SMD03025/4 series crystal, which is available in the frequency range from 8 - 285 MHz (oscillation mode: AT fundamental), is available with a frequency tolerance at +25°C of max. ±10 ppm. The temperature range extends from 0/+70°C to -40/+125°C. The temperature stability over the temperature range from 0/+70°C to -20/+70°C is ±10ppm, at -40/+85°C ±15ppm, at -40/+105°C ±30ppm and -40/+125°C ±50ppm. The ageing can be dimensioned to a maximum of ±10 ppm after 10 years, which means that the SMD03025/4 series oscillating quartz crystal is also used extensively in radio applications. In addition to the low price, the very low resistance and high accuracy are highly valued in radio applications.
Due to the low resistance, system energy can also be saved in battery-operated applications. Of course, reference designs for all radio ICs and radio SOCs available on the market are also available from us. The radio applications are all end products that use the DECT, LoRa, USB, Bluetooth ZigBee, Z-Wave, KNX, ISM band, WLAN (WiFi), NFC and BidCos radio standard. Of course, we also have oscillating crystals and crystal oscillators for 5G and IoT applications. But this little all-rounder is also used in very large quantities in industrial, embedded, medical and automotive applications. It goes without saying that we only supply 100% tested quartz crystals - no AQL, so that our components can be used for years with excellent performance and quality. In addition to a very broad and deep product range, our range of services includes a comprehensive design-in service as a real added value, which also includes very effective in-circuit tests of our SMD crystals. You can not only contact us via our website contact us but also configure your desired product in each product group and make an inquiry via the corresponding menu items, or request sample crystals immediately. Everything is quick and easy, so that we can support our customers very quickly and reliably in the development of the corresponding applications. In the 26 years of our company history, we have established ourselves as the experts for quartz crystals and oscillators.

FAQs
What advantages does an SMD crystal 3.2x2.5mm offer for MHz applications?
The SMD crystal in 3.2x2.5mm format with 4-pad ceramic housing is a very economical solution for many MHz clock applications. The LOW ESR resonator design, which supports a safe and fast transient response, is particularly advantageous. This also makes the crystal suitable for circuits in which the negative input resistances of the ICs or SoCs used are low or highly scattering. At the same time, developers benefit from excellent performance, high quality and a long service life. This makes this design a proven standard in cost-critical and demanding electronic applications.
For which frequency ranges and temperature requirements is the SMD quartz 3.2x2.5mm suitable?
The SMD03025/4 series crystal is available in the frequency range from 8 to 285 MHz in the AT base tone. It can be supplied with a maximum frequency tolerance of ±10 ppm at +25°C and thus covers precise clock applications. Depending on the version, the temperature range extends from 0/+70°C to -40/+125°C. Depending on the temperature window, the temperature stability is ±10 ppm, ±15 ppm, ±30 ppm or ±50 ppm, for example. This makes the module suitable for standard applications as well as for extended industrial and automotive temperature requirements.
Why is a LOW ESR SMD crystal 3.2x2.5mm particularly interesting for radio applications?
Low series resistance, high accuracy and reliable transient response are particularly important in radio applications. This is precisely where the SMD quartz 3.2x2.5mm with LOW ESR resonator design shows its strengths. It is therefore frequently used in applications with DECT, LoRa, USB, Bluetooth, ZigBee, Z-Wave, KNX, ISM band, WLAN, NFC or BidCos. Suitable frequency-generating solutions are also available for 5G and IoT applications. In addition, the low resistance in battery-operated devices can help to save system energy.
How precise and durable is the MHz SMD crystal in the 3.2x2.5mm housing?
The MHz SMD crystal in a 3.2x2.5mm housing is designed for high accuracy and long-term stable performance. A frequency tolerance of up to ±10 ppm at +25°C enables use in precise clock and radio applications. Ageing is also very manageable and can be dimensioned with a maximum of ±10 ppm after 10 years. This long-term stability is an important advantage for products with a long service life. In combination with the robust design, the quartz is therefore suitable for industrial, embedded, medical and automotive applications.
Are there alternatives to the SMD quartz 3.2x2.5mm if even smaller designs are required?
If the 3.2x2.5mm crystal is too large for an application, smaller alternatives are available. These include the 2.0x1.6mm/4pad SMD02016/4 series crystal and the even more compact 1.6x1.2mm/4pad SMD01612/4 series crystal. These variants also feature the LOW ESR resonator design and are therefore suitable for demanding clock applications. In addition, 32.768 kHz crystals are available in the dimensions 3.2x1.5mm, 2.0x1.2mm and 1.6x1.0mm. This means that the right crystal solution can be specifically adapted to the space requirement, frequency requirement and application.
