PCF1C331MCL1GS

The PCF1C331MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount radial can package. It provides 330 µF nominal capacitance at a 16 V rating with low ESR and high ripple capability for demanding power applications.

Designed for robust operation from -55°C to +105°C and qualified to AEC-Q200, this part targets applications that require high ripple current handling, compact SMD assembly, and endurance under elevated temperature conditions (2000 hours at 105°C).

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a tolerance of -20% to +20% at 16 V rated voltage.
• Low ESR / High Ripple Capability — ESR of 14 mΩ measured at 100 kHz and high-frequency ripple current rating of 5.0 A (100 kHz); low-frequency ripple current is 2.5 A (120 Hz), supporting high-current power stages.
• Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.12 measured at 20°C, 120 Hz, for predictable dissipation behavior.
• Temperature & Endurance — Rated for -55°C to +105°C operating range with a rated load life of 2000 hours at 105°C.
• Automotive Grade & Compliance — AEC-Q200 rated and RoHS compliant for regulated environments and automotive applications.
• SMD Packaging & Assembly — Surface-mount (radial, can - SMD) package sized φ10 × 12.7L with embossed carrier taping and moisture-proof packing; compatible with lead-free reflow soldering conditions up to a 260°C peak.
• Leakage Current — Specified leakage current of 1056 µA after application of rated voltage per datasheet conditions.

Typical Applications

• Automotive Power Electronics — Used on power rails, DC-DC converters and motor controller modules where AEC-Q200 qualification and high ripple endurance are required.
• Power Supply Filtering — Low ESR and high-frequency ripple capability make it suitable for output filtering and bulk decoupling in compact SMD power stages.
• Embedded Systems with Elevated Temperatures — The -55°C to +105°C range and 2000 h life at 105°C support designs exposed to wide temperature swings and continuous thermal stress.

Unique Advantages

• High ripple handling: 5.0 A (100 kHz) HF ripple current rating and 2.5 A at 120 Hz enable sustained current filtering in high-power circuits.
• Very low ESR: 14 mΩ at 100 kHz reduces loss and heat generation, improving efficiency in power conversion stages.
• Automotive-capable qualification: AEC-Q200 rating provides confidence for use in regulated automotive designs.
• Robust endurance: 2000 hours at 105°C load life supports long-term reliability under elevated temperature operation.
• SMD-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated assembly; compatible with lead-free reflow up to 260°C peak.
• Compact footprint: φ10 × 12.7L package size with recommended land size L: 1.03 × W: 1.03 cm saves board space while delivering high capacitance.
