Frequently Ask Questions

No official FAQ for this specific product has been found. However, some common questions about MLCCs are as follows:

• How to measure insulation resistance? When applying a DC voltage to an MLCC, a small leakage current will flow through it, and the corresponding resistance value is called the insulation resistance. During measurement, the rated voltage needs to be applied to the MLCC, and the resistance value is measured when the leakage current stabilizes (60 seconds or longer).
• What are ESR and ESL? In an actual MLCC, in addition to capacitance, there are parasitic components (resistance and inductance). The resistance component of the dielectric or electrode is called Equivalent Series Resistance (ESR), and the inductance component of the electrode or lead is called Equivalent Series Inductance (ESL).
• How to measure DC bias characteristics? MLCC (Class II) products have the characteristic of capacitance reduction when a DC voltage is applied, and it can be measured using a typical LCR meter. Pay attention to following specific test conditions during measurement, including frequency, AC voltage, DC voltage, and ambient temperature.
