What is the storage validity period of common electronic components?

Electronic componentsThe storage validity period varies depending on factors such as type, material, and environmental conditions. Here is an overview of the storage expiration dates for some common electronic components:

1. Integrated Circuit（IC）

· General validity periodUsually:1 to 5 years, depending on the manufacturer's specifications and storage conditions.

· matters needing attentionAvoid adverse environments such as high temperature, high humidity, and static electricity.

2. capacitor

· Aluminum electrolytic capacitorThe usual validity period is2 to 10 years, depending on the rated voltage and storage conditions.

· Ceramic capacitors: Generally storableMore than 10 years, but long-term storage may affect its performance.

3. resistor

· term of validityThere is usually no strict expiration date, but it is recommended toUse within 5 years to ensure stable performance.

4. Diode and transistor

· term of validityGenerally, it is5 to 10 years, depending on storage conditions.

5. Connectors and switches

· term of validityUsually:10 years or longer, depending on the material and environment.

6. Other special components

· Such as sensors, relays, etcThe validity period may beBetween 5 and 10 years, depending on the material and usage conditions.

Storage conditions

· temperatureIt should be stored in a dry and cool place, avoiding high temperature and humidity.

· humidityThe relative humidity should be controlled withinBetween 30% and 70%.

· static electricityAnti static measures should be taken to avoid electrostatic damage.

To ensure the performance and reliability of electronic components, it is recommended to follow the manufacturer's storage guidelines and regularly check the status of the components.
