PCW0E821MCO1GS

The PCW0E821MCO1GS is a surface-mount conductive polymer aluminum solid electrolytic capacitor designed for high-temperature reliability and low-ESR power filtering on 2.5 V rails. As a chip-type SMD can with AEC-Q200 qualification and RoHS compliance, it targets applications that require sustained ripple handling and stable capacitance up to 125°C.

Key value propositions include low equivalent series resistance, high ripple-current capability, and a rated ripple-load lifetime of 2000 hours at 125°C, making it suitable for demanding electronic power stages in automotive and industrial designs.

Key Features

• Capacitance & Voltage — 820 µF at a rated voltage of 2.5 V for bulk decoupling and energy storage on low-voltage power rails.
• High Temperature Reliability — Specified operating range −55°C to +125°C with endurance tested to 2000 hours at 125°C under rated ripple and DC bias.
• Low ESR — 14 mΩ (measured at 100 kHz, 20°C), minimizing losses and improving converter efficiency.
• High Ripple Current — 1.05 A at 120 Hz and 2.1 A at 100 kHz to support switching regulator and power-stage demands.
• Package & Mounting — Chip-type SMD (radial, can) designed for surface-mount assembly; recommended land size 8.3 mm × 8.3 mm with part dimensions L: 7 mm × D: 8 mm.
• Reflow & RoHS — Lead-free reflow profile compliant up to a 260°C peak; fully RoHS compliant (2011/65/EU, (EU)2015/863).
• AEC-Q200 Qualified — Meets AEC-Q200 designation for component-level reliability requirements.

Typical Applications

• Automotive electronic control modules — Bulk decoupling and energy buffering for 2.5 V power rails in AEC-Q200 qualified modules operating at elevated temperatures.
• DC–DC converters and power supplies — Low ESR and high ripple-current capability for switching regulators and point-of-load filtering.
• Industrial power electronics — Reliable smoothing and transient energy support where sustained performance to 125°C is required.

Unique Advantages

• Endurance at elevated temperature — Rated endurance of 2000 hours at 125°C under specified ripple and bias helps maintain capacitance and ESR stability in high-heat environments.
• Measured low ESR — 14 mΩ at 100 kHz reduces conduction losses and thermal build-up in high-frequency applications.
• High ripple handling — Specified ripple currents (1.05 A at 120 Hz, 2.1 A at 100 kHz) enable reliable operation with modern switching topologies.
• Surface-mount can format — Chip-type SMD package simplifies PCB placement and supports automated assembly with lead-free reflow up to 260°C.
• Quality and compliance — AEC-Q200 qualification and RoHS compliance provide traceable reliability and environmental conformity for regulated markets.
