Key Features

• Electrical Performance — 560 µF nominal capacitance at 20 V with ±20% tolerance; low equivalent series resistance of 20 mΩ measured at 100 kHz for improved transient response and lower dissipation.
• High Ripple Current — Rated ripple current of 2.2 A at 100 kHz and 1.1 A at 120 Hz, enabling effective smoothing and filtering in switching power stages.
• Thermal and Reliability — Rated for operation from −55 °C to +135 °C with a specified life of 4000 hours at 135 °C, supporting sustained high-temperature use.
• AEC-Q200 Qualification & RoHS Compliance — AEC-Q200 qualified for automotive-system level reliability and compliant with RoHS directives (2011/65/EU, (EU)2015/863).
• Surface-Mount Can Package — Chip-type radial can SMD with compact dimensions (L: 1 cm × D: 1 cm) and recommended land pattern (L: 1.03 cm × W: 1.03 cm) for PCB space efficiency.
• Assembly Compatibility — Designed for lead-free reflow soldering with a peak temperature capability of 260 °C, supporting modern SMT assembly processes.
• Endurance Characteristics — Meets datasheet endurance criteria: capacitance, tan δ, ESR and leakage limits after 4000 hours at 135 °C and specified damp-heat and soldering conditions per the PCH series datasheet.

Typical Applications

• Automotive power electronics — Suitable for engine control modules, in-vehicle DC-DC converters and other automotive power circuits where AEC-Q200 qualification and high-temperature tolerance are required.
• DC-DC converter output filtering — Low ESR and high ripple-current rating make it effective for output smoothing and energy-storage in switching regulators.
• Industrial power supplies — Long life at elevated temperature and robust damp-heat performance support continuous operation in industrial environments.
• Power modules and battery systems — Compact SMD can and high ripple capability aid in bulk decoupling and transient handling in battery-management and power distribution subsystems.

Unique Advantages

• High-temperature endurance: 4000 hours at 135 °C provides predictable lifetime performance in elevated-temperature designs.
• Low-loss power handling: 20 mΩ ESR at 100 kHz and 2.2 A ripple rating reduce thermal stress and enable higher efficiency in switching applications.
• Automotive-grade qualification: AEC-Q200 status supports inclusion in vehicle systems with defined reliability expectations.
• Compact SMD footprint: 1 cm × 1 cm package and defined land pattern enable dense PCB layouts without sacrificing capacitance.
• Assembly-ready: Compatible with lead-free reflow up to 260 °C for modern manufacturing flows.
