Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 25 V with ±20% tolerance, suitable where high bulk capacitance is required in a compact footprint.
• Low ESR — ESR of 16 mΩ measured at 100 kHz (20 °C), reducing losses and heat generation in high-frequency power circuits.
• High Ripple Current Capability — Supports 3.5 A ripple at 100 kHz and 525 mA at 120 Hz, enabling efficient smoothing in high-ripple designs.
• High-Temperature Reliability — Rated for -55 °C to 125 °C operation with a proven endurance of 4000 hours at 125 °C under DC bias plus rated ripple current.
• AEC-Q200 Qualified — Designed to meet automotive-grade reliability requirements; suitable for automotive electronics and other demanding industries.
• SMD Radial Can Package — Chip-type surface-mount radial can (L: 1.25 × D: 1.0 cm) for compact board-level placement; polarized device.
• Leakage & Endurance Characteristics — Leakage current: ≤0.01CV (µA) after 2 minutes at 20 °C; endurance limits include capacitance change within ±30% and ESR/tan δ within specified multipliers after life test per datasheet.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Battery Management Systems (BMS) — High ripple capability and high-temperature endurance make this capacitor suitable for BMS power conditioning and decoupling.
• Automotive Power Electronics — AEC-Q200 qualification and 125 °C endurance support use in automotive control modules and power subsystems.
