PCW0G122MCO1GS

The PCW0G122MCO1GS is a conductive polymer aluminum solid electrolytic chip capacitor from Nichicon's PCW series. It combines high capacitance (1200 µF) at a 4 V rating with low ESR and elevated-temperature endurance, targeting designs that require reliable power smoothing in demanding thermal environments.

Designed for surface-mount assembly in a compact φ8 × 10 mm can, this part delivers high ripple-current capability and long-life performance (2000 hours at 125°C), making it suitable for automotive-grade and high-reliability electronics.

Key Features

• Capacitance & Voltage — 1200 µF nominal capacitance at a 4 V rated voltage with ±20% tolerance for bulk energy storage and decoupling.
• High-temperature reliability — Endurance rating of 2000 hours at 125°C, with stable capacitance, tan δ and ESR after the endurance test.
• Low ESR & high ripple handling — ESR specified at 14 mΩ (100 kHz) and ripple current ratings of 1.15 A (120 Hz) and 2.3 A (100 kHz) to reduce power loss and improve thermal performance under AC loading.
• Leakage and loss characteristics — Leakage current specified at 1440 µA and tan δ of 0.08, providing predictable behavior in biased circuits.
• Automotive-grade qualification — AEC-Q200 qualified for use in automotive designs requiring component-level reliability validation.
• SMD can package & reflow compatible — Chip-type radial can (φ8 × 10 mm) supplied in embossed carrier taping with moisture-proof packing and compatibility with lead-free reflow conditions (260°C peak per datasheet guidance).
• Wide operating temperature — Specified for −55°C to +125°C operation to support designs across harsh thermal ranges.

Typical Applications

• Automotive electronics — Bulk smoothing and power stability in control modules and electronic subsystems that must meet automotive temperature and reliability demands.
• Communication equipment — Power rail decoupling and ripple attenuation in high-reliability communications hardware operating at elevated temperatures.
• Power supply filtering — Output filtering and energy storage where low ESR and high ripple current reduce losses and improve regulator stability.
• High-temperature electronics — Electronics and modules exposed to extended elevated-temperature conditions up to 125°C where long-life endurance is required.

Unique Advantages

• Proven high-temperature endurance: Rated for 2000 hours at 125°C, offering predictable long-term performance in hot operating environments.
• Improved thermal and ripple performance: Low ESR (14 mΩ at 100 kHz) and specified high-frequency/low-frequency ripple currents help minimize heat generation under AC stress.
• Automotive-ready qualification: AEC-Q200 rating supports integration into automotive and similarly demanding applications that require component-level qualification.
• Compact SMD can format: φ8 × 10 mm radial SMD package provides high capacitance density for space-constrained power modules.
• Manufacturing-ready packaging: Supplied in embossed carrier taping with moisture-proof packing and compatible with lead-free reflow profiles up to 260°C peak as specified.
• Regulatory compliance: RoHS compliant for use in regulated product designs.
