The application advantages of HOSONIC E3SB8 automotive-grade crystal oscillator in the connector of new energy vehicles

With the development trend of intelligence and high reliability in new energy vehicles, the connector, as a key hub for charging and communication, requires its core components to meet stringent automotive-grade standards. The HOSONIC E3SB8E crystal oscillator, with its AEC-Q200 certification and outstanding performance, provides comprehensive protection for the stable operation of the connector in complex automotive environments.

I. Automotive - grade certification endorsement ensures a high - reliability foundation

The HOSONIC E3SB8E crystal oscillator, which has passed the AEC - Q200 certification, has undergone numerous extreme tests. In the test of storing at 125℃ for 1,000 hours, the frequency stability of the crystal oscillator remains unaffected, ensuring that the connector can accurately output clock signals in the high - temperature environment of the engine compartment and charging pile of new energy vehicles. The 1,000 - cycle temperature cycling test between - 55℃ and 125℃ simulates the scenario of vehicles being frequently used in extreme climates, and the crystal oscillator frequency fluctuation is always controlled within ± 50ppm, effectively avoiding charging protocol communication interruption caused by drastic temperature changes. This high reliability lays a solid foundation for the long - term stable operation of the connector, which is in line with the automotive industry's strict requirement of "zero - failure" for components.

II. Strong vibration and shock resistance, adaptable to dynamic automotive working conditions

During the driving process of new energy vehicles, the connector has to withstand mechanical stress such as road bumps and engine vibrations. The crystal oscillator has passed the vibration test of 10Hz - 2000Hz, 1.5mm amplitude or 20G acceleration, as well as the mechanical shock test of 100g peak acceleration and 6ms half - sine wave. It ensures that the internal structure of the crystal oscillator is not damaged and continues to provide a stable frequency for the connector when the vehicle accelerates or decelerates sharply or passes through rugged roads. For example, in new energy vehicles equipped with autonomous driving functions, a stable crystal oscillator frequency can ensure that the connector accurately transmits sensor data and control commands during vehicle dynamic driving, enhancing the safety and reliability of the intelligent driving system.

III. Low failure risk, meeting long - life - cycle requirements

The annual aging rate of the crystal oscillator is controlled within ± 2ppm. Combined with the 1,000 - hour bias humidity test under conditions of 85℃, 80% - 85% humidity, and the 1,000 - hour working life test at 125℃, it effectively reduces the failure risk of the connector throughout the vehicle's life cycle. For new energy vehicle manufacturers, this means that there is no need to frequently replace the crystal oscillator inside the connector, greatly reducing after - sales maintenance costs. For users, the long - term stable performance of the connector can ensure the efficiency and safety of the charging process and reduce charging abnormalities caused by crystal oscillator aging.

IV. Enhanced electrical performance, matching automotive system requirements

With a high insulation resistance of 500MΩ and a shunt capacitance of ≤3pF, the crystal oscillator can effectively resist strong electromagnetic interference generated by the vehicle's motor and battery pack. This ensures zero - error data transmission in the connector during CAN - bus communication and charging protocol interaction scenarios. The low - power design of 8pF load capacitance and 100 - 200μW drive level not only meets the energy - saving requirements of new energy vehicles but also reduces the load on the vehicle's power supply, indirectly improving the vehicle's range. These electrical characteristics have been verified by automotive - grade standards and are highly compatible with the high - voltage, high - frequency, and high - integration characteristics of new energy vehicle systems.

V. Compact packaging and process optimization, compatible with automotive production standards

The 3225 surface - mount package meets the compact layout requirements of automotive space while being compatible with the JEDEC standard reflow soldering process (peak temperature 260℃, 3 reflows), ensuring high yield and good consistency of crystal oscillator soldering on the automotive parts automated production line. The miniaturized design can also reduce the weight of the connector, helping new energy vehicles achieve weight - reduction goals and in line with the industry's cost - reduction and efficiency - improvement development trend.

The HOSONIC E3SB8E automotive - grade crystal oscillator, with its automotive - grade reliability, stability, and compatibility, has become the core preferred component for new energy vehicle connectors. From high - temperature resistance and aging to strong vibration resistance, from low - power design to process optimization, it fully meets the requirements of automotive applications and provides key technical support for the safe and reliable operation of new energy vehicle charging and communication systems.
