OPPO newly introduces the A3 “Durability Champion” straight-screen smartphone, emphasizing durability and high performance. Renowned for its sleek design, the phone weighs just 178 grams and is as thin as 7.15 millimeters. It boasts a curved frame and ultra-narrow bezels, achieving a 93.7% screen-to-body ratio that balances both visual appeal and hand feel.
In terms of durability, the A3 has passed the Swiss SGS five-star drop resistance certification and military-grade tests. Leveraging Crystal Shield Glass technology, it enhances its drop resistance by 160% and scratch resistance by three times, ensuring resilience even in unexpected situations.
For the display, the A3 is equipped with an OLED bright screen supporting a 120Hz refresh rate and displaying 1.07 billion colors with a maximum brightness of 1200nits. Incorporating high-frequency PWM dimming and eye care technology, it offers users a smooth, detailed, and comfortable visual experience.
Powered by the Qualcomm Snapdragon 695 processor, the A3 packs a 5000mAh high-capacity battery with 45W fast charging technology. Officially, it promises to maintain over 80% battery health after 4 years, meeting users’ daily battery life needs.
Photography-wise, it sports a 50-megapixel main camera combined with advanced image processing algorithms, effortlessly capturing life’s beautiful moments in crisp, detailed images.
Furthermore, the A3 offers three fashionable color options: Mountain Stream Green, Aurora Purple, and Still Sea Black. Notably, the Mountain Stream Green variant utilizes a super-durable diamond-cut process, enhancing scratch and abrasion resistance while showcasing individuality and taste.
What are ESD components, and what is their importance in mobile phones? The significance of built-in ESD components.
ESD components are specialized electronic components designed to protect electronic devices from the effects of electrostatic discharge (ESD). Electrostatic discharge is a sudden release of electrical charge that can potentially damage electronic devices, leading to device malfunctions or a shortened lifespan. ESD components are designed to absorb, conduct, or dissipate electrostatic discharges to prevent damage caused by static electricity.
In mobile phones, the primary role of ESD components is to protect the internal electronic components from the harm caused by electrostatic discharge. Various circuits and components inside the phone are highly sensitive to ESD, which is why multiple ESD components are typically used in the phone’s design to provide protection. These components may include diodes, ESD diode, MOSFET and more.
Specifically, ESD components in a mobile phone may serve the following purposes:
Interface Protection: Various interfaces of the phone, such as the charging port and headphone jack, may require ESD components to prevent damage from electrostatic discharge.
RF Circuit Protection: RF circuits in mobile phones are highly sensitive to ESD and require ESD components to safeguard these critical circuits.
Processor and Memory Protection: Processors, memory, and other crucial components in the phone also require ESD protection to ensure the device’s normal operation.
Touchscreen and Display Protection: The touchscreen and display are integral parts of a mobile phone that also require ESD components to prevent static electricity damage.
In summary, ESD components play a crucial role in protecting the internal electronic components of a mobile phone from damage caused by electrostatic discharge, ensuring the phone’s proper operation and longevity.
Say goodbye to static troubles! A well-known brand in Shenzhen, Crystal Electronics, has developed the TT0311SA-Fx ultra-low capacitance component. It can quickly react within nanoseconds when electrostatic discharge occurs, suppressing surge voltage instantly, ensuring that the phone’s internal RF circuits and/or baseband circuits are not affected by electrostatic discharge. Its low capacitance feature also guarantees interference-free signals, preventing data packet loss and improving call quality.”
