5pcs 100pf ceramic capacitor

🔹 5PCS 100pF Ceramic Capacitor – Multilayer Ceramic Chip (MLCC)

High-quality multilayer ceramic capacitors (MLCCs) with a capacitance of 100 picofarads. Essential components for high-frequency filtering, RF coupling, oscillator timing, and noise suppression in digital and analog circuits. A fundamental value for tuning, resonant circuits, and EMI reduction.

✅ Specifications:

• Capacitance: 100 Picofarads (pF) / 0.1 Nanofarads (nF) / 0.0001 Microfarads (µF)

• Tolerance: Typically ±5% (J), ±10% (K), or ±20% (M)

• Voltage Rating: Commonly 50V DC (Check code on component)

• Dielectric Type: Class 1 (COG/NP0) for high stability or Class 2 (X7R, X5R) for general use.

• Package / Size: 0805 (2.0mm x 1.25mm) is common. Other sizes: 0603, 1206.

• Temperature Coefficient:

  • COG/NP0: ±30ppm/°C (Excellent stability, near-zero drift)

  • X7R: ±15% from -55°C to +125°C

• Marking Code: Often marked “101” (10 x 10¹ pF = 100 pF)

• Quantity: 5 pieces

⚙️ Key Features:

• Non-Polarized: Can be installed in either direction.

• Low ESR & High Q: Excellent for high-frequency and resonant circuit applications.

• Stable (COG/NP0): Minimal change in capacitance with voltage, temperature, or time. Ideal for precise timing.

• Compact & Reliable: Ceramic construction offers long life in a tiny package.

• Wide Applications: A standard capacitor value used in RF, digital, and analog circuits.

📦 Typical Applications:

• RF & High-Frequency Circuits: Coupling and decoupling in RF amplifiers, filters, and antenna matching networks.

• Oscillator & Timing Circuits: In crystal oscillator load capacitors (e.g., for 16MHz crystals, two 18-22pF caps are typical; 100pF may be used in specific LC or RC oscillators).

• Snubber Networks: Across switch contacts (relays, triacs) to suppress high-frequency noise and arcing.

• EMI Filtering: In combination with ferrite beads to filter high-frequency noise on power or signal lines.

• Digital Logic Decoupling: High-speed decoupling close to IC power pins to suppress very high-frequency noise (often used alongside bulk 0.1µF caps).

🔧 Identification & Usage Notes:

• Marking: Ceramic capacitors often have a 3-digit code. 101 is the code for 100pF:

  • First two digits (10): Significant figures

  • Third digit (1): Multiplier (number of zeros) → 10 x 10¹ pF = 100 pF

• SMD Soldering: Use reflow, solder paste, or careful hand soldering with a fine tip.

• Voltage Rating: Ensure the capacitor’s voltage rating exceeds your circuit’s maximum. A 50V rating is safe for most low-voltage circuits.

⚠️ Important Considerations:

• Dielectric Choice Matters:

  • For timing, tuning, or filters, use COG/NP0.

  • For general bypass/decoupling, X7R is fine.

• DC Bias Effect: Class 2 ceramics (X7R, X5R) lose significant capacitance when DC voltage is applied. For critical applications, use COG/NP0 or derate heavily.

• Microphonics: Ceramic capacitors can be piezoelectric, potentially converting vibration into electrical noise in sensitive audio circuits.

• Not for High-Precision Analog: Unless using COG/NP0, tolerance and drift can be significant. For precision analog filters, use film capacitors.
