PCL1C681MCL1GS

The PCL1C681MCL1GS is a surface-mount conductive polymer aluminum electrolytic capacitor designed for automotive and other high-reliability power applications. It delivers high capacitance (680 µF) in a compact SMD can package (φ10 × 12.7 mm) with low ESR and high ripple-current capability for power smoothing and decoupling on compact PCBs.

Engineered for long-term operation, this device is specified for 20,000 hours at 105°C and is AEC‑Q200 qualified. It combines low loss (tanδ) and robust leakage/ripple performance to support demanding operating environments.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 16 V, with a capacitance tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Low ESR — ESR of 14 mΩ measured at 20°C, 100 kHz, supporting efficient high-frequency decoupling and reduced power loss.
• High Ripple Current — Low-frequency ripple current 2.35 A (120 Hz) and high-frequency ripple current 4.7 A (100 kHz) for robust smoothing in switching power stages.
• Long Life Endurance — Rated for 20,000 hours at 105°C, providing durability for extended-duty applications.
• Wide Temperature Range — Operational from −55°C to +105°C, suitable for harsh thermal environments.
• Solid Conductive Polymer — Combines the reliability of solid electrolytic construction with low loss (tanδ 0.12 at 20°C, 120 Hz) and predictable electrical characteristics.
• Automotive Grade — AEC‑Q200 qualified for use in automotive systems where AEC validation is required.
• SMD Package & Packaging — Radial can SMD (chip type) in φ10 × 12.7L format; supplied in embossed carrier taping with moisture-proof packing for pick-and-place assembly.
• RoHS Compliant — Meets RoHS directive requirements.

Typical Applications

• Automotive power systems — Bulk smoothing and decoupling in automotive power rails where high ripple-current handling and long life at elevated temperature are required.
• On-board DC‑DC converters — Output filtering and transient suppression for converters operating up to 16 V, leveraging low ESR and high-frequency ripple capability.
• Power supply modules — Local energy storage and smoothing in compact SMD power modules that benefit from high capacitance density and robust endurance.

Unique Advantages

• High capacitance in a compact footprint: 680 µF in a φ10 × 12.7 mm SMD can reduces board area while maintaining energy storage capacity.
• Low-loss operation: tanδ of 0.12 (20°C, 120 Hz) and 14 mΩ ESR at 100 kHz minimize dissipation and improve converter efficiency.
• High ripple capability: Rated ripple currents of 2.35 A (120 Hz) and 4.7 A (100 kHz) support demanding switching environments and lower temperature rise.
• Long thermal endurance: 20,000 hours at 105°C provides predictable long-term performance in high-temperature applications.
• AEC‑Q200 qualification: Enables use in automotive-grade designs that require AEC validation and higher reliability assurance.
• Production-friendly packaging: Embossed carrier taping with moisture-proof packing supports automated assembly and storage handling.
