PCF1C181MCL4GS

The PCF1C181MCL4GS is a surface-mount conductive polymer aluminum electrolytic capacitor in Nichicon's PCF series, rated 180 µF at 16 V. Engineered for applications that require low equivalent series resistance (ESR), high ripple handling and long endurance, it supports robust operation across a wide temperature range.

Key value propositions include low ESR (16 mΩ at 100 kHz), high ripple current capability (2.2 A at 120 Hz and 4.4 A at 100 kHz), and a 2000 hour life at 105°C, making it suitable where reliable power filtering and stability under thermal stress are required.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with ±20% tolerance and a rated voltage of 16 V.
• Low ESR — ESR of 16 mΩ measured at 20°C / 100 kHz, supporting low-loss power delivery and efficient decoupling.
• High Ripple Current — Handles 2.2 A at 120 Hz (low frequency) and 4.4 A at 100 kHz (high frequency), enabling effective smoothing under significant AC stress.
• Thermal Performance & Endurance — Rated operating range of −55°C to +105°C with a rated load life of 2000 hours at 105°C.
• Tangent of Loss Angle (tan δ) — Specified tan δ of 0.12 (measured at 20°C, 120 Hz), supporting predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 576 µA after standard conditioning.
• Package & Mounting — SMD radial can package, size φ8 × 12L (L: 1.2 × D: 0.8 cm), surface-mount with recommended land size 8.3 × 8.3 mm; supplied in embossed carrier taping with moisture-proof packing.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, supporting automotive-grade reliability and environmental compliance.

Typical Applications

• Automotive Electronics — Suited for automotive electronic modules that require AEC-Q200 qualification, wide temperature range, and 2000 h endurance at 105°C.
• Power Supply Filtering — Effective for smoothing and decoupling on 16 V rails where low ESR and high ripple current capacity reduce voltage ripple and thermal stress.
• Embedded Power Systems — Use in compact surface-mount power delivery circuits where high ripple handling and a small φ8 × 12L footprint are beneficial.

Unique Advantages

• Low-loss operation: The 16 mΩ ESR at 100 kHz minimizes voltage drop and heat generation in high-frequency power stages.
• High ripple tolerance: 2.2 A (120 Hz) and 4.4 A (100 kHz) ripple ratings support aggressive switching and high-current transient environments.
• Automotive-capable qualification: AEC-Q200 qualification and a −55°C to +105°C operating range enable deployment in automotive-grade electronic systems.
• Long operational life: 2000 hours at 105°C provides predictable aging characteristics for designs requiring durable performance over time.
• Surface-mount convenience: SMD radial can and embossed carrier taping with moisture-proof packing simplify automated assembly and inventory handling.
