PCG0G181MCL1GS

The PCG0G181MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD radial can package, optimized for higher capacitance in compact footprints. It delivers 180 µF at 4 V with low ESR and rated ripple current characteristics suitable for demanding power applications.

Designed for automotive-class environments (AEC-Q200 rated), this part targets power smoothing, decoupling and energy-storage roles where low impedance, wide temperature span and endurance are required.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 4 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Low ESR & High Ripple Capability — ESR of 32 mΩ at 100 kHz and ripple current ratings of 950 mA at 120 Hz and 1.9 A at 100 kHz support high-frequency decoupling and power stabilization.
• Automotive Qualification — AEC-Q200 rating indicates suitability for automotive system use as specified in the product data.
• Temperature & Endurance — Operates from −55°C to +105°C with an endurance rating of 2000 hours at 105°C under applied rated voltage.
• Stable Impedance Across Temperature — Temperature characteristics specify Z(+105°C)/Z(+20°C) ≤ 1.25 and Z(−55°C)/Z(+20°C) ≤ 1.25 at 100 kHz, supporting consistent performance over the operating range.
• Surface-Mount Can Package — Chip-type radial can SMD package with compact dimensions (L: 6 × D: 5 mm) and recommended land pattern L: 5.3 × W: 5.3 mm for PCB implementation.

Typical Applications

• Automotive Power Modules — Bulk smoothing and decoupling for control modules and power distribution networks where AEC-Q200-rated components are required.
• DC–DC Converter Output — Output filtering and energy storage for converters that benefit from low ESR and high ripple current capability.
• Infotainment and ECU Systems — Local decoupling near sensitive regulators and ICs to stabilize supply rails across temperature and long service life.

Unique Advantages

• Compact, High Capacitance Footprint: 180 µF in a 6 × 5 mm chip can reduces PCB area while providing substantial energy storage.
• Low-Frequency and High-Frequency Ripple Support: Specified ripple currents at 120 Hz and 100 kHz combined with 32 mΩ ESR enable both bulk smoothing and high-frequency decoupling.
• Automotive-Grade Reliability: AEC-Q200 rating and 2000-hour endurance at 105°C demonstrate suitability for automotive system lifecycles.
• Wide Operating Temperature: −55°C to +105°C range maintains performance across harsh thermal environments common in vehicle and industrial applications.
• Predictable Thermal Impedance Behavior: Tight impedance ratios across −55°C to +105°C at 100 kHz support consistent design margins for temperature-sensitive power rails.
