PCL1C391MCL1GS

The PCL1C391MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a chip-type SMD package designed for high-reliability power applications. It delivers high capacitance (390 µF) at a 16 V rating with low equivalent series resistance and elevated ripple-current capability.

Built for demanding environments, this part offers a long operational life of 20000 hours at 105°C, AEC‑Q200 qualification, and RoHS compliance—making it suitable for automotive and other reliability-focused designs that require compact, high-performance bulk capacitance.

Key Features

• Capacitance & Voltage — 390 µF rated capacitance at 16 V with ±20% tolerance (specified at 120 Hz, 20°C).
• Low ESR — 18 mΩ ESR measured at 100 kHz, enabling improved power delivery and reduced losses on high-frequency rails.
• High Ripple Current — 1.95 A at 120 Hz and 3.9 A at 100 kHz, supporting heavy AC stress and switching-power applications.
• Long-Life Endurance — Rated for 20000 hours at 105°C with defined limits for capacitance, tan δ, ESR and leakage current after endurance testing.
• Temperature Range — Operates from −55°C to +105°C, suitable for wide environmental conditions.
• Automotive-Grade Qualification — AEC‑Q200 qualified to meet automotive reliability requirements.
• SMD Package & Assembly — Chip-type radial can SMD package; compatible with lead-free reflow soldering with a 260°C peak condition (single reflow at ≤260°C allowed).
• Compact Footprint — Component dimensions L: 1.2 × D: 0.8 cm with recommended land size 8.3 × 8.3 mm, enabling high-density board layouts.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Power Rails — Bulk decoupling and smoothing for ECU and power distribution circuits where long life at elevated temperature and AEC‑Q200 qualification are required.
• DC–DC Converters — Input/output filtering on converters and voltage regulators benefitting from low ESR and high ripple-current capability at both low and high frequencies.
• Infotainment & HVAC Systems — Power conditioning for in-vehicle electronics that demand stable capacitance over extended thermal stress.
• Sensor and Actuator Power Supply — Local energy storage and transient suppression for sensors and actuators in harsh-temperature environments.

Unique Advantages

• Extended high-temperature life: 20000 hours at 105°C ensures retained capacitance and controlled ESR/tan δ after long-term thermal stress.
• High AC performance: Low 18 mΩ ESR and multi-frequency ripple-current ratings support both switching and low-frequency power demands.
• Automotive-grade reliability: AEC‑Q200 qualification provides an assurance level aligned to automotive component requirements.
• Assembly-friendly SMD form factor: Chip-type radial can SMD enables compact board placement and lead-free reflow soldering up to a 260°C peak (single reflow allowed at ≤260°C).
• RoHS compliance: Meets applicable environmental directives for lead-free design and manufacturing.
