402F37433 Crystals and their Applications in the Automotive Industry

Crystals are an essential component of modern technology, used in both electronics and automotive engineering. They are employed in everything from cellular phones and laptop computers, to car engines and suspension systems. A particular crystal, the 402F37433, is renowned for its use in car components and its application range is vast.The 402F37433 is an AT-cut crystal made from silica, specifically designed for use in the automotive industry. AT cuts are unique in that they provide a greater frequency stability than other cuts offered from a single-element crystal. This makes them ideal for applications which require a crystal oscillator to continually generate accurate and consistent frequencies, such as in vehicle powertrains and engine control systems.This crystal is composed of a quartz resonator, attached to a lead frame, then housed in an epoxy package. It is often accompanied by a P-CAD for ease of installation on board. The package is designed in such a way that it minimises vibration and environmental noise, allowing for one of the most reliable crystallised frequencies available. Coupled with its durability, this makes it well suited to current automotive electronics standards.The 402F37433 contains a number of features which make it particularly ideal for automotive applications. It operates from 0-100°C and is able to make use of the recently released 5V power supply standard, a new automotive du jour. With this particular crystal’s range of operating temperatures, it can endure the full scope of extreme temperatures often encountered in the motor world.This AT-cut crystal is further customised for car use through its robustness. Its trimmer is designed to take up less space and offer better performance in automobiles. It also takes the form of a low-profile package, making it more appealing to release engineers and designers.In terms of usage, the 402F37433 is employed in a variety of automotive industry applications. It can be used as a frequency standard in various powertrain controls and other components such as throttle position sensors, ignition controls, engine management systems, and even in noise- tolerant sensors. It can also be used in advanced driver assistance systems, anti-lock brakes, and in the newest era of automotive control modules.The use of the 402F37433 crystal oscillator in the motor world is testimony to the advances in automotive technology and engineering. Its accuracy and stability combined with its low profile make it the ideal choice for a vast range of applications in the automobile and transportation field. Its growth in popularity will not be hindered, as its capabilities have proved unrivaled in the automotive industry, so manufacturers and engineers alike can be sure that this crystal will continue to offer reliable and robust solutions for years to come.
