PCX1D181MCL1GS

The PCX1D181MCL1GS is a conductive polymer aluminum solid electrolytic capacitor in a surface-mount can package, rated 180 µF at 20 V. Designed for demanding environments, it combines low ESR, high ripple current capability and long-life endurance for robust power decoupling and bulk storage in electronics.

Targeted use cases include automotive electronic systems and other temperature-challenged designs that require AEC-Q200 qualification, wide operating range and extended high-temperature life without sacrificing power-handling performance.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a 20 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Conductive Polymer Construction: Solid polymer electrolyte for improved reliability and stable electrical characteristics versus conventional electrolytes.
• Low ESR: 28 mΩ ESR specified at 100 kHz, supporting low-loss performance in high-frequency power applications.
• High Ripple Current: 400 mA at 120 Hz and 800 mA at 100 kHz ratings for effective smoothing and decoupling under heavy switching loads.
• Long Life at Elevated Temperature: Endurance specified to 3000 hours at 125°C, supporting prolonged operation in high-temperature environments.
• Automotive-Grade Reliability: AEC-Q200 qualification and an operating temperature range of −55°C to +125°C for automotive and industrial use.
• Surface-Mount Can Package: Radial can SMD package suitable for automated assembly; compatible with lead-free reflow soldering to a 260°C peak.
• Compact Footprint: Component dimensions approximately 1.0 × 1.0 cm with recommended land pattern ~1.03 × 1.03 cm for PCB layout.
• Polarized Device: Polar capacitor; orientation must be observed in PCB assembly and system design.

Typical Applications

• Automotive Power Rails: Bulk decoupling and smoothing for ECU power supplies and onboard converters where AEC-Q200 qualification and high-temperature endurance are required.
• DC–DC Converters: Input/output filtering and energy buffering in high-frequency switch-mode power supplies that benefit from low ESR and high ripple capability.
• Infotainment & Gateway Modules: Power stability and transient handling in vehicle or industrial communication modules operating across wide temperature ranges.
• Industrial Power Electronics: Local energy storage and filtering in motor drives, sensors and control modules exposed to thermal stress and vibration-prone environments.

Unique Advantages

• Long High‑Temperature Endurance: 3000 hours at 125°C reduces maintenance and replacement frequency in elevated-temperature applications.
• Improved Power Efficiency: Low ESR (28 mΩ at 100 kHz) lowers conduction losses and improves regulator stability under switching loads.
• High Ripple Handling: Rated ripple currents (400 mA @120 Hz, 800 mA @100 kHz) enable reliable operation with high switching activity.
• Automotive-Qualified: AEC-Q200 rating and −55°C to +125°C operating range simplify qualification for vehicle electronics and other demanding systems.
• SMT Compatibility: Surface-mount can format and lead-free reflow compatibility streamline automated assembly and high-volume production.
• Compact PCB Footprint: 1.0 × 1.0 cm component size with ~1.03 × 1.03 cm recommended land pattern conserves board space while providing substantial capacitance.
