PCW0G181MCO1GS

The PCW0G181MCO1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for high-reliability applications. It pairs low ESR and high ripple-current capability with a compact SMD can package to support demanding power-conditioning and decoupling tasks.

Targeted at automotive and other high-temperature environments, this AEC‑Q200 qualified part delivers stable performance across −55°C to 125°C and is compatible with lead‑free reflow processes up to a 260°C peak.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance at a rated voltage of 4 V with ±20% tolerance for bulk decoupling and energy storage.
• Low ESR — 17 mΩ ESR measured at 100 kHz, supporting efficient power delivery and reduced heat generation under load.
• High Ripple Current — 1.72 A at 100 kHz and 860 mA at 120 Hz, enabling reliable handling of switching and ripple currents in power circuits.
• High‑Temperature Endurance — Ripple load life of 2000 hours at 125°C, with endurance specifications that limit capacitance, tan δ and ESR changes after test.
• Automotive Qualification — AEC‑Q200 qualified for designs requiring industry-recognized reliability validation.
• Surface-Mount, Reflow Compatible — Chip‑type SMD can package sized L: 6 × D: 5 mm, compatible with lead‑free reflow soldering up to a 260°C peak (single reflow at 260°C).
• Wide Operating Temperature — Specified for −55°C to +125°C to cover extended temperature ranges common in rugged electronics.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Automotive power conditioning — Bulk decoupling and smoothing in ECUs, sensor modules, and DC‑DC converters where AEC‑Q200 qualification and high-temperature endurance are required.
• Power supply filtering — Output filtering for switching regulators and converters that demand low ESR and high ripple‑current capability.
• Embedded and industrial electronics — Local energy storage and transient suppression in systems exposed to wide temperature ranges and continuous ripple stress.

Unique Advantages

• High ripple-handling capacity: Low ESR (17 mΩ at 100 kHz) and rated ripple currents (1.72 A at 100 kHz) reduce thermal stress and improve regulator stability.
• Designed for high-temperature operation: 2000 h ripple load life at 125°C provides proven endurance for demanding thermal environments.
• Automotive-grade reliability: AEC‑Q200 qualification supports use in automotive systems requiring standardized reliability screening.
• Reflow-friendly SMD form factor: Chip can package with lead‑free reflow compatibility (260°C peak, single reflow) simplifies PCB assembly for modern manufacturing flows.
• Compact footprint: Small L: 6 × D: 5 mm package and recommended land size (5.3 × 5.3 mm) enable high-density board layouts while providing substantial capacitance.
