Crystals are ubiquitous components in the fields of electronics, communication, navigation and navigation systems. CA-301 50.1900M-K, or simply called ‘PB Free’, is a type of crystal technology developed specifically to reduce electromagnetic interference (EMI). The specific components of this technology are composed of substrate material and two different active layers.

The substrate material of the PB Free is a combination of quartz and gallium arsenide, making it extremely resilient and reliable. This technology also features two active layers composed of different types of crystals; one is a low-leakage layer, while the other is a high-sensitivity layer. This structure improves the efficiency and the overall performance of the crystals.

PB Free crystals are specifically used for applications requiring low EMI. This is because the high-sensitivity layer reduces the amount of unwanted noise from near-by electrical sources, while the low-leakage layer blocks out most of the external interference. As a result, PB Free crystals are ideal for low EMI applications such as automotive electronics, consumer electronics, industrial electronics, medical electronics, and telecommunications.

The working principle of PB Free crystals is based on the use of highly-stable quartz di-electric materials. This material’s natural electrical properties allow it to filter out unwanted frequencies, while simultaneously providing enough power to the active two-layer structure. This two-layer structure is then used to generate a specific signal frequency. The signal is then transmitted through the quartz material and detected by the receiver.

In addition to having improved EMI performance, PB Free crystals also feature excellent temperature stability, low cost, and high output power. Furthermore, these crystals are available in both surface mount and through-hole packages, making them suitable for a wide range of applications.

Overall, PB Free crystals provide a cost-effective, reliable and efficient solution to reduce electromagnetic interference in a variety of applications. Their unique two-layer structure combined with the highly-durable quartz substrate material makes them an ideal choice for any application that requires EMI protection.
