PCW0G561MCO1GS

The PCW0G561MCO1GS is a conductive polymer aluminum solid electrolytic chip capacitor designed for surface-mount applications that demand high temperature capability and long ripple-load life. Built for demanding environments, this SMD can withstand service temperatures from -55°C to +125°C and is qualified to meet AEC-Q200 requirements.

With low ESR and elevated ripple-current ratings, the device is targeted at designs that require robust power decoupling and smoothing under sustained thermal and electrical stress, while supporting lead‑free reflow assembly (260°C peak soldering condition).

Key Features

• Conductive polymer aluminum construction — Solid electrolyte design for reliable performance at elevated temperatures and improved stability compared with traditional electrolytics.
• Rated capacitance and voltage — 560 µF nominal capacitance at a 4 V rating with ±20% tolerance, suitable for low-voltage power rail applications.
• Low ESR and high ripple capability — 15 mΩ ESR measured at 100 kHz and ripple current ratings of 1.075 A (120 Hz) and 2.15 A (100 kHz) enable efficient power smoothing and reduced thermal loss.
• High-temperature endurance — Ripple-load life of 2000 hours at 125°C; designed to meet endurance criteria with capacitance, tan δ and ESR retention after test.
• Automotive-grade qualification — AEC-Q200 qualified to support automotive system requirements where that qualification is requested.
• Surface-mount, reflow-compatible packaging — Chip-type radial can SMD package (L: 7 × D: 8 mm) with a recommended land pattern of 8.3 × 8.3 mm, compatible with lead‑free reflow (260°C peak as specified).
• Wide operating temperature range — Specified for -55°C to +125°C operation to support high-temperature environments.
• Regulatory compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power systems — Energy buffering and power-rail smoothing in modules where AEC-Q200 qualification and 125°C endurance are required.
• Power supply decoupling — Low ESR and high ripple current capability support stable operation of DC–DC converters and local regulators.
• High-reliability electronics — Long ripple-load life and thermal endurance make it suitable for control electronics and modules exposed to elevated temperatures.

Unique Advantages

• Durable high-temperature operation: 2000 hours ripple-load life at 125°C provides predictable long-term behavior in hot environments.
• Efficient power handling: Low 15 mΩ ESR and high ripple-current ratings reduce losses and heat generation on power rails.
• Automotive-capable qualification: AEC-Q200 status supports use in automotive electronic designs that require component-level qualification.
• Assembly-ready SMD form factor: Chip-type radial can with specified land pattern and lead‑free reflow compatibility simplifies PCB integration and manufacturing flow.
• Regulatory assurance: RoHS compliance supports deployment in products requiring restricted-substance conformity.
