PCG1A331MCL1GS

The PCG1A331MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a compact surface-mount can package. It provides 330 µF capacitance with a 10 V rating and is designed for applications requiring low ESR, high ripple handling and stable performance across a wide temperature range.

Targeted for automotive and other demanding electronic systems, this part combines a small φ8 × 7 mm footprint with AEC‑Q200 qualification and long endurance to support robust power filtering and decoupling in space-constrained designs.

Key Features

• Capacitance & voltage — 330 µF nominal capacitance with ±20% tolerance, rated for 10 V operation.
• Conductive polymer construction — Solid electrolytic architecture for stable performance and electrical characteristics consistent with polymer technology.
• Low ESR — 23 mΩ equivalent series resistance measured at 100 kHz and 20°C, enabling lower loss and improved transient response on power rails.
• High ripple current capability — Supports 1.55 A at 120 Hz (low frequency) and 3.1 A at 100 kHz (high frequency), suitable for demanding switching environments.
• Leakage current — Specified leakage current of 660 µA after rated voltage application, supporting predictable standby and bias behavior.
• Temperature and endurance — Rated for operation from −55°C to +105°C with endurance of 2000 hours at 105°C per the series specification.
• Compact SMD package — φ8 × 7 mm radial can SMD (chip type) with recommended land size of 8.3 × 8.3 mm for PCB integration.
• Packaging and production — Supplied in embossed carrier taping with moisture-proof packing; part is in mass production.

Typical Applications

• Automotive electronics — AEC‑Q200 rated component for use in vehicle electronic modules requiring durable decoupling and filtering under temperature and vibration stress.
• DC‑DC converters — Low ESR and high ripple current capability make it suitable for output smoothing and bulk decoupling in switching power stages.
• On-board power rails — Compact footprint and stable leakage characteristics support local rail stabilization on space-constrained PCBs.

Unique Advantages

• Designed for high ripple environments: Specified 1.55 A (120 Hz) and 3.1 A (100 kHz) ripple currents reduce voltage ripple and thermal stress in switching applications.
• Low-loss performance: 23 mΩ ESR at 100 kHz (20°C) improves efficiency and transient response compared with higher‑ESR alternatives.
• Wide operating range: −55°C to +105°C rating supports use across diverse thermal environments.
• Automotive-capable qualification: AEC‑Q200 rating aligns the part with automotive system requirements where that qualification is required.
• Small SMD form factor: φ8 × 7 mm package and SMD mounting simplify board layout and enable high-density assemblies.
• Production-ready packaging: Embossed carrier taping with moisture-proof packing supports automated assembly and inventory handling.
