Resonant crystals with low ESR offer particularly low resistances and therefore enable the oscillator to start up quickly and reliably. This is particularly important in low-power designs and in critical applications where a stable start of the clock source is crucial. The LRT technology described on this page has been specially developed for excellent performance and high frequency stability. For industrial applications, this means a robust and process-safe solution with high reliability. At the same time, the optimized oscillation behaviour helps to avoid unstable operating states and the resulting field returns.

The range includes both THT and SMD oscillating crystals and therefore covers a wide variety of design requirements. Designs ranging from compact 1.2 × 1.0 mm NANO crystals to classic THT HC-49/U or HC-49/US-SMD packages are available. Resistance-optimized NANO and MICRO-SMD crystals such as SMD01210/4, SMD01612/4 and SMD02016/4 are available for very small applications. The SMD03025/4 MINI SMD crystal is suitable for universal and cost-effective designs, allowing both space-critical and classic layouts to be designed with suitable oscillating crystals.

Numerous oscillating crystals from the range are suitable for demanding automotive and medical applications. The website explicitly states that many products are automotive-ready and that AEC-Q200-qualified variants are available. These include several SMD oscillating crystals and selected 32,768 kHz clock crystals. Fast transient response, high stability and reliable long-term performance are particularly important in these areas. The combination of low ESR, tested quality and suitable designs supports their use in demanding electronic systems.

For 32,768 kHz applications, several SMD clock crystals are available for different space requirements. The M3215 is a very frequently used SMD clock crystal and is also available as a reduced resistance version with a maximum of 50 kOhm for low-power designs and automotive applications. If the M3215 is too large, the M2012 offers a cost-effective alternative with a smaller design. The M1610, which is also available as a reduced resistance version with a maximum of 60 kOhm, is intended for particularly compact applications. This allows reliable real-time clock solutions to be implemented even in very small devices.

PETERMANN-TECHNIK offers a wide and deep range of vibrating quartz crystals, so that suitable solutions are immediately available for many applications. Many products are available directly from stock, while other variants can be provided within a very short time. Using the product configurators, desired parameters can be defined quickly and suitable quartz crystals can be requested directly. Samples can also be ordered with just a few clicks, which simplifies evaluation during the development process. Suitable quartz solutions can also be offered for existing designs or as an EOL alternative.

PETERMANN-TECHNIK is a strong choice for quartz crystals because the range combines cost-effective product solutions with excellent quality, performance and long-term availability. The quartz crystals are based on the in-house developed LRT technology and are manufactured with in-house manufactured quartz resonators and 100% tested. This ensures immediate, reliable transient response, high frequency stability and a component quality that minimizes field returns. In addition, there is a very wide range of designs, fast delivery and numerous variants suitable for the automotive industry. For developers and purchasers in the industry, this means high security of supply, technical reliability and efficient product selection.
