Mastering Standard Capacitance Values: A Guide to Capacitor

Standard capacitance values are crucial in electronics as they streamline capacitor selection and ensure circuit stability. Preferred values, typically determined by the E series (a geometric progression), simplify capacitor choice. Tolerance, expressed as a percentage, allows for allowable variations in capacitance. Tolerance codes, such as "E6" or

6 FAQs about [Capacitor mandrel inspection standards]

What are the quality standards for chip capacitors?

In addition to the external visual characteristics, quality standards for internal microstructure of the chip capacitor are also applicable, as viewed on polished cross sections of capacitor samples. Units are sectioned along the long and short dimension of the capacitor to provide two edge views of the internal electrodes and terminals.

What are the visual standards for chip capacitors?

After describing high reliability testing in our previous article, let’s discuss visual standards for chip capacitors. Multilayer ceramic capacitors (MLCCs) must possess fine workmanship and physical integrity, so visual inspection of the product is performed at 20X magnification to check for defects in the capacitor body and end metallization.

How to test a capacitor?

Unless otherwise stated in the detail specification, the test shall be carried out with non-activated flux. Capacitors shall be subjected to Test Ta of IEC 60068-2-20 either using the solder bath method (method 1), or the soldering iron method (method 2) as prescribed be the detail specification.

What are the test severities for a capacitor?

Test severities for capacitor volumes above 12,000 mm3 are under consideration. Unless otherwise specified in the detail specification, DC voltage of an amplitude necessary to produce a current of 10 mA/F or more shall be applied to the capacitor in the forward direction.

What is the test UC for a capacitor?

The capacitors shall be subjected to IEC 60068-2-21, Test Uc, as applicable. Method A, severity 2 (two successive rotations of 180°) shall be used. This test shall not apply is in the detail specification the terminations are described as rigid and to components with unidirectional terminations designed for printed wiring applications.

What is capacitor fundamentals?

Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.
