Film Capacitors (CL23B Series) | Lighting systems, power supplies, motor drives | - Material: Polypropylene film (IEC 60252) - Rated Voltage: 100V (Base) ▲ 150V (Advanced) (IEC 60252) - Tolerance: ±5% (Base) ▲ ±2% (Advanced) (IEC 60068-2-5) - Breakdown Voltage: Equal to rated voltage (IEC 60384-14) | - High pulse/overload endurance - Stable over temperature ranges - Long lifespan (20+ years) | - Higher cost vs ceramics/tantalum - Bulky compared to multilayer ceramics |
Ceramic Capacitors | High-frequency circuits, decoupling | - Material: Class X7R/Y5V ceramic (IEC 60384-8) - Voltage: Up to 100V (IEC 60384-8) - Tolerance: ±10% (IEC 60068-2-5) | - Compact size - Low Equivalent Series Resistance (ESR) - Cost-effective for low-voltage apps | - Capacitance drift with temperature/voltage - Limited voltage rating (max 100V) |
Tantalum Electrolytic | IC decoupling, audio filtering | - Material: Tantalum oxide (IEC 60384-4) - Voltage: 10V–100V (IEC 60384-4) - Tolerance: ±10% (IEC 60068-2-5) | - High capacitance/volume ratio - Stable in high-temperature environments | - Catastrophic failure risk (overvoltage) - Voltage-sensitive (requires protection) |
Aluminum Electrolytic | Power supplies, audio smoothing | - Material: Aluminum oxide (IEC 60384-4) - Voltage: 16V–450V (IEC 60384-4) - Tolerance: ±20% (IEC 60068-2-5) | - High capacitance at low cost - Suitable for high-voltage applications | - Polarized (DC only) - Shorter lifespan (5–10 years) - Bulky for high capacitance |
Polyester Capacitors | Audio crossover networks, RF applications | - Material: Polyester film (IEC 60384-11) - Voltage: Up to 200V (IEC 60384-11) - Tolerance: ±5% (IEC 60068-2-5) | - Low dissipation factor - Stable over wide temperature ranges | - Less robust than polypropylene film - Limited voltage for high-frequency use |
Ceramic Multilayer | High-density PCB decoupling | - Material: Multilayer X5R ceramic (IEC 60384-8) - Voltage: 16V–100V (IEC 60384-8) - Tolerance: ±10% (IEC 60068-2-5) | - Tiny footprint (0402–1206 packages) - Low Equivalent Series Inductance (ESL) | - Capacitance drift with temperature - Voltage rating drops with capacitance |
