Understanding Vishay Tantalum Capacitor Date Codes

Tantalum capacitors are widely used in electronic circuits due to their high reliability, long lifespan, and stability. Vishay is a well-known brand in the industry, and their tantalum capacitors are popular among engineers and designers. One important aspect of Vishay tantalum capacitors is their date code, which provides crucial information about the component's manufacturing date and other relevant details.

What is a Date Code?

A date code is a series of alphanumeric characters printed on the capacitor's body, which identifies the part number, manufacturing date, and other relevant information. The date code is usually composed of a combination of letters and numbers, and it's essential to understand its meaning to ensure the correct selection and application of the capacitor.

Vishay Tantalum Capacitor Date Code Structure

The Vishay tantalum capacitor date code consists of four parts: the part number, the manufacturing site code, the year and week code, and the batch code.

Part Number

The part number is a unique identifier assigned to each product by Vishay. It typically starts with a "T" or "293" followed by a series of numbers and letters. The part number specifies the capacitor's characteristics, such as its capacitance, voltage rating, and ESR.

Manufacturing Site Code

The manufacturing site code is a two-digit code that indicates the location where the capacitor was manufactured. For example, "01" represents the Vishay facility in Columbus, Ohio, USA.

Year and Week Code

The year and week code is a four-digit code that specifies the capacitor's manufacturing date. The first two digits represent the year (e.g., "20" for 2020), and the last two digits represent the week of the year (e.g., "14" for the 14th week of the year).

Batch Code

The batch code is a unique identifier assigned to each production batch. It typically consists of a single letter or a combination of letters and numbers.

Interpreting the Date Code

To interpret the date code, you need to decode each part of the code. Let's take an example:

TAj 155 2014 01

  • Part Number: TAJ 155
  • Manufacturing Site Code: 01 (Columbus, Ohio, USA)
  • Year and Week Code: 2014 (Year 2020, Week 14)
  • Batch Code: 01 (Production batch identifier)

Conclusion

Understanding the Vishay tantalum capacitor date code is crucial for ensuring the correct selection and application of the component. By decoding the date code, you can determine the capacitor's manufacturing date, manufacturing site, and other relevant information. This knowledge helps you make informed decisions about component selection, inventory management, and quality control.

Remember

  • Always verify the date code with the capacitor's datasheet or manufacturer's documentation.
  • Ensure that you're using the correct capacitor for your application to avoid any potential issues or failures.
  • Properly store and handle tantalum capacitors to prevent damage and maintain their reliability.
