• Low Equivalent Series Resistance (ESR) — 19 mΩ measured at 20 °C / 100 kHz, helping reduce power loss and heating under AC ripple conditions.
• High-Temperature Endurance — Rated endurance of 3000 hours at elevated temperatures (125 °C and 135 °C for 25–50 V units), enabling sustained operation in hot environments.
• Wide Operating Temperature — −40 °C to 135 °C operation for reliability across automotive thermal ranges.
• Physical & Mounting — Radial lead can package, size φ18 × 35.5 mm L, lead spacing 7.5 mm (±0.5 mm), supplied in bulk or bag packing for through‑hole assembly.
• Electrical Loss Characteristics — Measured tangent of loss angle (tan δ) of 0.32 at 20 °C, 120 Hz (device-specific measurement condition).
• Leakage Current — Specified leakage current of 7500 µA (with generic datasheet guidance of 0.03CV after 1 minute at 20 °C).
• Compliance & Qualification — RoHS compliant and AEC-Q200 qualified for automotive application support.

Typical Applications

• Automotive control modules — Suitable for control circuits in vehicles where high capacitance and elevated ripple handling are required.
• Electric power steering systems — Used in power electronics and control circuits that demand bulk energy storage and reliable high-temperature performance.
