BUY SMD OSCILLATING CRYSTALS CHEAP FOR RADIO APPLICATIONS
We provide you with inexpensive LOW ESR SMD crystals for all types of radio applications. The resistor-optimized resonator designs have been specially designed for very fast and reliable transient response, even if the negative input resistances of the oscillator stages of the radio ICs or SOCs used are low or vary greatly. Of course, we have reference designs for many radio ICs and SOCs on the market. Typical applications in which our SMD oscillating crystals have been used successfully for many years include all end products that use the DECT, LoRa, USB, Bluetooth, ZigBee, Z-Wave, KNX, ISM band, WLAN (WiFi), NFC and BidCos radio standards. Of course, we also have oscillating crystals and crystal oscillators for 5G and IoT applications. The most widely used miniaturized ceramic housing of our SMD crystals in radio applications has the dimensions 3.2x2.5mm with 4 solder pads - our SMD03025/4 series.
In order to meet the demand for further miniaturization, our very extensive product range naturally also includes LOW ESR crystals in the ceramic packages 2.5x2.0mm/4pads - our SMD02502/4 series - 2.0x1.6mm/4pads - our SMD02016/4 series - and 1.6x1.2mm/4pads - our SMD01612/4 series. Depending on the package size, the frequency spectrum from 8 - 285 MHz is covered in the fundamental tone. There is therefore a high-quality product solution for every crystal frequency used in the radio sector. This makes it very easy to implement circuits with two capacitors on ground (pierce-oscillator design).
Inexpensive SMD oscillating crystals from Petermann Technik
The frequency tolerance at +25°C is ±10 ppm max. The most accurate temperature stabilities are ±10ppm above -20/+70°C, ±15ppm above -40/+85°C, ±30ppm above -40/+105°C, and ±50 ppm above -40/+125°C. Ageing after 10 years is ±10 ppm max.
We recommend the 3.2x2.5mm/4pad housing for design-in. If this hermetically sealed ceramic housing is too large, then our next design-in recommendation is the 2.0x1.6mm/4pad housing, or the LOW ESR radio crystals in the 1.6x1.2mm/4pad, if the 2.0x1.6mm/4pad housing is also too large. In addition to a very extensive 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 simply contact us via our website info(at)petermann-technik.de, 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 crystals and oscillators.
Of course, we also offer 32.768 kHz crystals with the dimensions 3.2x1.5mm, 2.0x1.2mm and 1.6x1.0mm.
How do we ensure the product performance of our entire product range, including our oscillating crystals for radio applications? Not through simple AQL tests, but through 100% testing, so that our components can be used for years with excellent performance and quality.

FAQs
What are LOW ESR SMD crystals and why are they particularly suitable for radio applications?
LOW ESR SMD resonant crystals are resistance-optimized resonators that have been specially developed for fast and reliable transient response. They are particularly suitable for radio applications if the negative input resistances of the radio ICs or SoCs used are low or highly scattering. As a result, stable oscillator circuits can be reliably realized even in demanding RF applications. PETERMANN-TECHNIK offers these crystals for numerous radio standards such as Bluetooth, LoRa, ZigBee, Z-Wave, WLAN, NFC or DECT. Suitable oscillating crystals and crystal oscillators are also available for modern 5G and IoT applications.
What housing sizes are available for SMD oscillating crystals for wireless applications?
PETERMANN-TECHNIK offers several miniaturized ceramic housings for radio applications. The most commonly used format is 3.2x2.5 mm with 4 solder pads in the SMD03025/4 series. The range also includes LOW ESR crystals in 2.5x2.0 mm, 2.0x1.6 mm and 1.6x1.2 mm, each also with 4 pads. This allows developers to select the right size depending on space requirements and design objectives. The 3.2x2.5 mm housing is initially recommended for the design-in; alternatively, smaller designs are available for more miniaturized applications.
What frequency range do SMD quartz crystals cover in the fundamental tone?
Depending on the housing size, the SMD oscillating crystals cover a frequency range from 8 to 285 MHz in the fundamental tone. This means that a suitable product solution is available for practically every crystal frequency used in the radio sector. The crystals are designed in such a way that simple Pierce oscillator circuits with two capacitances against ground can be realized. In addition, 32.768 kHz crystals are also available in compact designs such as 3.2x1.5 mm, 2.0x1.2 mm and 1.6x1.0 mm. The wide range supports both classic radio applications and modern networked systems.
What tolerances and temperature stabilities do SMD oscillating crystals from PETERMANN-TECHNIK offer?
The frequency tolerance of the SMD oscillating crystals is a maximum of ±10 ppm at +25 °C. Depending on requirements, very precise variants are available for temperature stability, for example ±10 ppm over -20 to +70 °C or ±15 ppm over -40 to +85 °C. In addition, versions with ±30 ppm over -40 to +105 °C and ±50 ppm over -40 to +125 °C are also available. Ageing after 10 years is a maximum of ±10 ppm. This makes the crystals suitable for durable and reliable industrial radio applications.
How does PETERMANN-TECHNIK support the design-in of SMD oscillating crystals?
PETERMANN-TECHNIK supports customers with a comprehensive design-in service for SMD oscillating crystals for radio applications. This includes reference designs for many radio ICs and SoCs on the market, which makes integration into new developments much easier. In addition, the service includes very effective in-circuit tests to ensure the function of the crystals directly in the application. Customers can use the website to configure their desired product, make inquiries or request sample crystals immediately. This provides fast, reliable and practical support for development projects.
