220pf CERAMIC CAPACITOR

The 221 ceramic capacitor is a common type of capacitor used in electronics, defined by its small size, non-polarity, and low cost.

💎 221 Ceramic Capacitor Details

Decoding the Value

The designation 221 is a standard code that specifies the capacitor's capacitance and tolerance:¹

• 221 (Capacitance): This is a three-digit code where the first two digits are the significant figures, and the third digit is the multiplier (the number of zeros).
• 221 = 220pF
• J (Tolerance): The letter 'J' indicates a tolerance of pm 5%. This means the actual capacitance value is guaranteed to be within 5% of 220pF.

Core Characteristics

• Type: Multilayer Ceramic Capacitor (MLCC). It uses ceramic material as the dielectric.
• Polarity: It is non-polarized, meaning it can be connected in any direction in an AC or DC circuit.
• Frequency Response: It offers a good frequency response and is effective at bypassing high-frequency noise.
• Common Applications: Widely used for decoupling (or bypassing) the power supply line near integrated circuits (ICs) to filter out high-frequency noise, and for general-purpose timing or filtering circuits
