PCG0G681MCL1GS

The PCG0G681MCL1GS is a Nichicon conductive polymer aluminum solid electrolytic capacitor in a chip-type surface-mount can. It delivers 680 µF capacitance at a 4 V rating in a compact φ8 × 7 mm package optimized for high-capacitance, low-ESR power decoupling and smoothing.

Designed for demanding operating conditions, this part combines low ESR (21 mΩ at 100 kHz), high ripple current capability, an extended temperature range of -55°C to 105°C, and AEC-Q200 rating to address automotive and other high-reliability power applications.

Key Features

• Capacitance and Tolerance — 680 µF nominal capacitance with ±20% tolerance (120 Hz, 20°C) for bulk energy storage and decoupling on low-voltage rails.
• Rated Voltage — 4 V DC rated voltage suitable for low-voltage power rails.
• Low ESR — 21 mΩ ESR measured at 100 kHz and 20°C, enabling efficient high-frequency filtering and reduced power loss.
• High Ripple Current — 1.6 A at 120 Hz (low frequency) and 3.2 A at 100 kHz (high frequency) to support switching regulators and transient loads.
• Tangent of Loss Angle (tan δ) — 0.12 specified at 20°C, 120 Hz to characterize dielectric losses.
• Leakage Current — 544 µA initial leakage current measured after rated voltage application conditions.
• Endurance and Temperature Range — 2000 hours at 105°C endurance rating and an operating temperature range of -55°C to 105°C for extended reliability in elevated-temperature environments.
• Package and Assembly — Chip-type radial can SMD in φ8 × 7 mm size with embossed carrier taping and moisture-proof packing for automated surface-mount assembly.
• Qualification — AEC-Q200 rated for use in applications requiring automotive-grade component qualification.

Typical Applications

• Automotive electronics — Suitable for automotive systems that require AEC-Q200-rated components and a wide operating temperature range.
• Automotive power rails — Use on low-voltage power rails where 680 µF bulk capacitance, low ESR, and high ripple current capability help stabilize DC-DC converter outputs and suppress ripple.
• Compact surface-mount power designs — The φ8 × 7 mm chip-type SMD package enables high-capacitance placement in space-constrained boards.
• High-temperature environments — Rated to operate from -55°C to 105°C with 2000 hours endurance at 105°C for sustained thermal reliability.

Unique Advantages

• High capacitance in a small SMD can — 680 µF in a φ8 × 7 mm package reduces board area for bulk energy storage compared with larger through-hole alternatives.
• Low ESR and strong ripple handling — 21 mΩ ESR and up to 3.2 A high-frequency ripple current minimize losses and improve regulator stability under dynamic loads.
• Automotive-grade qualification — AEC-Q200 rating and wide temperature range make the part suitable for automotive and other reliability-focused designs.
• Endurance at elevated temperature — 2000-hour life at 105°C supports long-term performance in sustained high-temperature operation.
• Assembly-ready packaging — Embossed carrier taping with moisture-proof packing simplifies surface-mount manufacturing and handling.
• Low loss characteristics — tan δ of 0.12 (20°C, 120 Hz) supports predictable AC loss behavior in filtering applications.
