PCR1C681MCL1GS

The PCR1C681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in Nichicon’s PCR series. It combines low equivalent series resistance (ESR) and high ripple-current capability in a compact surface-mount radial can package.

Designed for demanding environments, this device targets automotive and other high-reliability electronics where extended life at elevated temperatures and lead‑free reflow compatibility are required.

Key Features

• Core Technology Conductive polymer aluminum solid electrolytic construction for inherently low ESR and stable performance.
• Capacitance & Rated Voltage 680 µF rated capacitance at 16 V for bulk energy storage and decoupling in compact designs.
• Low ESR & High Ripple Current ESR 19 mΩ at 100 kHz (20°C) with ripple current ratings of 1.6 A at 120 Hz and 3.2 A at 100 kHz, enabling efficient power delivery and reduced losses.
• Extended High‑Temperature Life 4,000 hours at 125°C endurance rating, with capacitance and ESR retention specified after endurance.
• Wide Operating Temperature Rated for −55°C to +125°C operation to support harsh-condition electronics.
• Surface‑Mount Package & Reflow Chip (radial, can - SMD) package with surface mount land size 1.03 × 1.03 cm and qualified for lead‑free reflow soldering to a 260°C peak.
• Automotive Qualification & Environmental Compliance AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronics — Suited for in-vehicle power modules and control units that require AEC‑Q200 qualification and reliable operation at elevated temperatures.
• Power supply filtering and decoupling — Low ESR and high ripple-current capability make it suitable for smoothing and decoupling on DC‑DC converters and power rails.
• Harsh‑environment electronics — The −55°C to +125°C operating range and 4,000‑hour high‑temperature endurance support systems exposed to wide temperature swings.

Unique Advantages

• Low-loss power handling: 19 mΩ ESR at 100 kHz and high ripple-current ratings reduce dissipation and improve converter efficiency.
• Proven high‑temperature endurance: 4,000 hours at 125°C provides extended lifetime for designs that must tolerate sustained elevated temperatures.
• Automotive-grade qualification: AEC‑Q200 status supports use in applications demanding automotive reliability standards.
• Lead‑free reflow compatibility: SMD construction and 260°C peak reflow support modern lead‑free assembly processes.
• Compact footprint: 1.0 × 1.0 cm nominal size and defined land pattern simplify board layout for space‑constrained designs.
• ESR stability after endurance: ESR limits are specified to remain within defined bounds after endurance and at −40°C, aiding predictable long-term performance.
