👉 Rainproof is a technical term in the field of electronics and electrical engineering. It refers to an electronic component or device that has been designed to withstand extreme weather conditions such as heavy rainfall, which can cause damage to the component. Rainproof components are typically made from materials that resist water and other liquids, and they often have special features, such as a high resistance rating or a low capacitance, to prevent moisture from entering the circuit. Rainproof components are commonly used in electronic devices like smartphones,
