PCH1E331MCL1GS

The PCH1E331MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package, delivering 330 µF at 25 V. It combines low ESR and high ripple-current capability with a wide operating temperature range and long high-temperature endurance, making it suitable for demanding electronic power applications.

Built to series-level specifications that include AEC-Q200 qualification and RoHS compliance, this part targets environments that require reliable, high-temperature operation and robust power filtering in compact surface-mount form factors.

Key Features

• Capacitance & Voltage: 330 µF rated at 25 V with a tolerance of ±20% at 120 Hz, 20°C, providing bulk energy storage for power rails.
• Conductive Polymer Dielectric: Solid electrolyte construction for low ESR and improved ripple handling versus traditional wet electrolytics.
• Low ESR & High Ripple Current: ESR of 20 mΩ at 100 kHz and ripple current ratings of 1.1 A at 120 Hz and 2.2 A at 100 kHz for effective smoothing and decoupling in high-frequency power circuits.
• High-Temperature Endurance: Rated operating range of −55°C to +135°C with a guaranteed lifetime of 4000 hours at 135°C under rated voltage.
• SMD Can Package & Reflow Compatible: Chip-type radial can in an SMD package designed for lead-free reflow soldering with a 260°C peak soldering condition.
• Reliability & Compliance: AEC-Q200 qualified and RoHS compliant (2011/65/EU, (EU)2015/863), with leakage current specified at not more than 0.03CV after 2 minutes’ application of rated voltage.
• Compact Footprint: Package dimensions approximately 1.0 cm × 1.0 cm with a recommended land size of 1.03 cm × 1.03 cm to support dense PCB layouts.

Typical Applications

• Automotive Electronic Modules — Use in control units and power electronics where AEC-Q200 qualification and high-temperature endurance (4000 h at 135°C) are required.
• DC–DC Converters and Power Supplies — Low ESR and high ripple-current capability support output filtering and bulk decoupling in high-frequency power stages.
• Industrial Power Electronics — Compact SMD can package and wide temperature range make it suitable for harsh industrial environments that demand long-term stability.

Unique Advantages

• High-Temperature Reliability: 4000 hours endurance at 135°C under rated voltage preserves capacitance and performance in elevated-temperature applications.
• Superior Ripple Handling: Low ESR (20 mΩ at 100 kHz) and measured ripple currents (1.1 A at 120 Hz, 2.2 A at 100 kHz) reduce voltage ripple on power rails.
• Automotive-Grade Qualification: AEC-Q200 qualification supports deployment in automotive-grade designs that require component-level reliability evidence.
• Assembly-Ready SMD Design: Chip-type can and compatibility with lead-free reflow up to 260°C simplify surface-mount assembly and reflow processes.
• Regulatory Compliance: RoHS compliance ensures the part meets current restricted-substance requirements for commercial and automotive programs.
• Compact, PCB-Friendly Size: Approximately 1.0 cm × 1.0 cm body and a 1.03 × 1.03 cm recommended land pattern allow high-density placement on multilayer boards.
