PCG1C681MCL1GS

The PCG1C681MCL1GS is a conductive polymer aluminum solid electrolytic capacitor from Nichicon's PCG series, designed as a compact surface-mount chip with higher capacitance in a radial can SMD package. It delivers a combination of high capacitance (680 µF), low ESR and substantial ripple-current capability for demanding power applications.

Targeted for applications that require robust electrical performance across a wide temperature range, this part carries an AEC-Q200 rating and is specified for endurance under elevated temperature conditions, making it suitable for automotive and other high-reliability systems.

Key Features

• Capacitance & Tolerance — 680 µF nominal with ±20% tolerance at 120 Hz, 20°C, providing bulk energy storage in a compact SMD form factor.
• Rated Voltage — 16 V DC rated voltage suitable for common low-voltage power rails.
• Low ESR — 18 mΩ equivalent series resistance measured at 100 kHz, 20°C, enabling low-loss operation in high-frequency circuits.
• High Ripple Current Capability — 2.05 A at 120 Hz (low frequency) and 4.1 A at 100 kHz (high frequency), supporting applications with significant AC stress on capacitors.
• Leakage Current — Specified leakage current of 2176 µA.
• Temperature Range — Rated for operation from −55°C to +105°C to withstand wide thermal environments.
• Endurance / Reliability — Life specification of 2000 hours at 105°C; endurance performance criteria include defined limits for capacitance change, tan δ and ESR after the test period.
• Package & Assembly — Radial can, SMD chip package (φ10 × 12.7 mm), supplied in embossed carrier taping and moisture-proof packing for automated surface-mount assembly; surface-mount land size 1.03 × 1.03 cm.

Typical Applications

• Automotive power electronics — AEC-Q200-rated SMD capacitor for automotive subsystems where wide temperature range and endurance are required.
• DC‑DC converter output filtering — High capacitance and high-frequency ripple-current capability make it suitable for smoothing outputs in compact power modules.
• High-ripple power rails — Low ESR (18 mΩ) and high ripple current ratings support use in circuits with sustained AC stress on bulk capacitors.

Unique Advantages

• High ripple-current handling: 4.1 A at 100 kHz and 2.05 A at 120 Hz reduce thermal stress and improve reliability in high‑duty power circuits.
• Low-loss operation: 18 mΩ ESR at 100 kHz, 20°C minimizes voltage drop and heat generation under dynamic load.
• Automotive-capable: AEC-Q200 rating provides an explicit qualification path for automotive system integration.
• Wide operating temperature: −55°C to +105°C rating supports deployment across harsh thermal environments.
• Durability at elevated temperature: 2000-hour endurance at 105°C with defined limits on capacitance, tan δ and ESR ensures predictable long-term performance.
• Production-ready packaging: Embossed carrier taping and moisture-proof packing streamline automated placement and inventory handling in volume manufacturing.
