PCM1D681MCL1GS

The PCM1D681MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon's PCM series. It delivers 680 µF at 20 V in a compact surface-mount radial can package optimized for demanding, high-temperature environments.

Designed for high-reliability applications, this SMD capacitor combines low ESR and high ripple current capability with long-term stability — including AEC-Q200 qualification, RoHS compliance, and an 8000-hour rated life at 125°C — making it well suited to robust electronics and automotive systems.

Key Features

• Dielectric / Construction: Conductive polymer aluminum solid electrolyte in a chip-type SMD radial can package for compact, high-capacitance SMD designs.
• Capacitance & Voltage: 680 µF rated capacitance at 20 V with ±20% tolerance (at 120 Hz, 20°C), providing substantial bulk energy storage in a small footprint.
• Low ESR & High Ripple Capability: 14 mΩ ESR measured at 100 kHz and ripple current ratings of 3.5 A at 100 kHz and 1.75 A at 120 Hz, supporting high-frequency power stages and smoothing duties.
• Wide Temperature Range: Operates from −55°C to +125°C, with specified impedance stability across temperature (Z(+125°C)/Z(+20°C) ≤ 1.25 and Z(−55°C)/Z(+20°C) ≤ 1.25 at 100 kHz).
• Long Life & Endurance: Rated for 8000 hours at 125°C; endurance criteria include capacitance change within ±20%, tan δ ≤ 150% of initial, and ESR ≤ 200% of initial after endurance testing.
• Assembly & Soldering: Lead‑free reflow compatible with peak 260°C (reflow allowed up to two times at ≤260°C); pre‑heat and soldering heat resistance specified for robust assembly.
• Qualification & Compliance: AEC‑Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), supporting regulated and automotive-grade designs.
• Size & Land Pattern: Compact footprint: L 1.27 × D 1.00 cm, recommended surface mount land size L 1.03 × W 1.03 cm for PCB layout.

Typical Applications

• Automotive Electronics: AEC‑Q200 qualification and 8000-hour life at 125°C make this capacitor suitable for electronic control units and other automotive systems that demand high-temperature reliability.
• High-temperature Power Electronics: Low ESR and high ripple current ratings support DC‑DC converters, power stages, and voltage regulation in elevated-temperature assemblies.
• Surface-mount, Ruggedized Assemblies: Lead‑free reflow compatibility to 260°C and defined soldering heat resistance simplify integration into modern SMT production flows for rugged applications.

Unique Advantages

• High energy density in an SMD can: 680 µF at 20 V provides substantial capacitance for bulk storage while keeping PCB footprint compact.
• Lower losses at high frequency: 14 mΩ ESR at 100 kHz and 3.5 A ripple capability reduce thermal stress and improve power-stage efficiency.
• Designed for prolonged high‑temperature operation: 8000 hours life at 125°C with strict endurance limits ensures predictable performance over extended duty cycles.
• Automotive-grade qualification: AEC‑Q200 qualification and RoHS compliance support use in regulated automotive and industrial applications.
• Reflow-ready for modern assembly: Verified lead‑free reflow to 260°C (two passes maximum) and soldering heat resistance simplify manufacturing and rework processes.
