PCA1H181MCL1GS

The PCA1H181MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for high-reliability applications. As a surface-mount, low-ESR capacitor it targets systems that require robust ripple-current handling, extended high-temperature endurance and AEC-Q200 qualification for automotive use.

Key value propositions include low equivalent series resistance for improved power delivery, guaranteed ripple-current performance across frequencies, and a long rated life of 4000 hours at 125°C for demanding thermal environments.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 50 V nominal.
• Low ESR & Ripple Handling — 19 mΩ ESR measured at 100 kHz and rated ripple currents of 4.6 A at 100 kHz and 2.3 A at 120 Hz, enabling effective high-frequency power filtering.
• High-Temperature Endurance — Rated life of 4000 hours at 125°C with endurance specifications for capacitance, ESR and leakage current defined after DC bias plus rated ripple current.
• Temperature Range — Operates from −55°C to +125°C with controlled impedance characteristics across temperature extremes.
• Surface-Mount Package — Chip-type, radial can SMD package with compact dimensions (L: 1.27 × D: 1.00 cm) and recommended land size of 1.03 × 1.03 cm for PCB layout.
• Assembly & Environmental Compliance — Compatible with lead-free reflow soldering peak of 260°C and RoHS compliant (2011/65/EU, (EU)2015/863).
• Automotive Qualification — AEC-Q200 compliant for use in automotive applications requiring component-level qualification.
• Post-Endurance Performance — ESR specification includes measurement after endurance at −40°C, ensuring low-temperature performance is characterized after stress.

Typical Applications

• Automotive electronics — For automotive control modules and electronic subsystems where AEC-Q200 qualification, high ripple tolerance and elevated temperature endurance are required.
• High-reliability power systems — Suitable for power-supply filtering and decoupling in electronics that demand long-life performance at elevated temperatures.
• Surface-mount assemblies — Designed for SMD production flows with lead-free reflow compatibility (260°C peak) to support modern PCB assembly processes.

Unique Advantages

• High ripple-current capability: Rated ripple currents of 4.6 A (100 kHz) and 2.3 A (120 Hz) reduce thermal stress in high-frequency power rails.
• Low ESR: 19 mΩ at 100 kHz provides improved voltage stability and power delivery for sensitive electronics.
• Extended high-temperature life: 4000 hours at 125°C gives predictable long-term performance in thermally demanding environments.
• Automotive-ready qualification: AEC-Q200 compliance supports use in automotive applications where component-level qualification is required.
• Reflow and RoHS compliant: Lead-free reflow to 260°C and RoHS conformity enable modern assembly and environmental standards.
• Characterized post-endurance performance: ESR and other parameters are specified after endurance and at −40°C, aiding reliable low-temperature behavior assessments.
