SAMSUNG Multilayer Ceramic Capacitors (MLCC)

The capacitance of a Multilayer Ceramic Capacitor (MLCC)

The capacitance of a Multilayer Ceramic Capacitor (MLCC) can vary widely depending on the specific capacitor’s construction and intended use. MLCCs are available in a wide range of capacitance values, from picofarads (pF) to microfarads (µF) and beyond. They are commonly used in electronic circuits for their high capacitance density and reliability. The capacitance value of an MLCC is typically indicated by a three-digit code, where the first two digits are the significant figures and the third digit is the multiplier. For example, a code of “104” indicates a capacitance of 10 x 10^4 pF, or 100,000 pF (100 nF).

The tolerance of a Multilayer Ceramic Capacitor (MLCC)

The tolerance of a Multilayer Ceramic Capacitor (MLCC) refers to the range within which the actual capacitance of the capacitor is expected to fall relative to its rated capacitance value. MLCCs are available in different tolerance ratings, which are typically expressed as a percentage.

Common tolerance values for MLCCs include:

• ±1%
• ±2%
• ±5%
• ±10%
• ±20%

For example, if you have an MLCC with a rated capacitance of 10 µF and a tolerance of ±10%, its actual capacitance could range from 9 µF to 11 µF. Tolerance is an important consideration when selecting capacitors for precision applications where the accuracy of the capacitance value is critical.

The voltage rating of a Multilayer Ceramic Capacitor (MLCC)

The voltage rating of a Multilayer Ceramic Capacitor (MLCC) indicates the maximum voltage that the capacitor can safely withstand across its terminals. Exceeding this voltage rating can lead to capacitor failure, including short circuits or even explosion in extreme cases.

MLCCs are available in a wide range of voltage ratings to suit different applications. Common voltage ratings for MLCCs include:

• 6.3V
• 16V
• 25V
• 50V
• 100V
• 250V
• 500V
• 1000V

When selecting an MLCC for a specific application, it is important to choose a capacitor with a voltage rating that is higher than the maximum voltage expected in the circuit to ensure reliable operation and avoid damage to the capacitor.

The temperature coefficient of a Multilayer Ceramic Capacitor (MLCC)

The temperature coefficient of a Multilayer Ceramic Capacitor (MLCC) refers to how the capacitance of the capacitor changes with temperature. It is typically expressed in parts per million per degree Celsius (ppm/°C). The temperature coefficient indicates the rate of change of capacitance over a specified temperature range.

MLCCs are available with different temperature coefficients, which include:

• X7R: This is a common temperature coefficient for MLCCs and indicates that the capacitance will change by ±15% over the specified temperature range, typically -55°C to +125°C.
• X5R: This temperature coefficient indicates that the capacitance will change by ±15% over a wider temperature range, typically -55°C to +85°C.
• C0G (NP0): This is a temperature coefficient of nearly zero, meaning that the capacitance change with temperature is minimal over a wide temperature range, typically -55°C to +125°C. C0G MLCCs are often used in applications where temperature stability is critical.

The temperature coefficient is an important consideration when selecting MLCCs for applications where the capacitance must remain stable over a wide temperature range.
