Key Features

• Capacitance & Voltage — 82 µF nominal capacitance with a 100 V rated voltage and tolerance ±20% at 120 Hz, 20 °C.
• Low Loss — tanδ 0.08 measured at 20 °C, 120 Hz, delivering low dissipation for efficient power filtering.
• Low Impedance — specified impedance of 500 mΩ, helping to reduce voltage ripple and improve transient response in power rails.
• Ripple Current Capability — Low frequency ripple current 351 mA at 120 Hz and high frequency ripple current 540 mA at 10 kHz for effective AC stress handling.
• Leakage Current — Leakage current specified as 246 µA for predictable standby behavior.
• Thermal & Lifetime — Operating range −55 °C to +105 °C with rated endurance of 5000 hours at 105 °C.
• Package & Mounting — Radial lead (through-hole) can, size φ10 × 25 mm with 5.0 mm lead spacing (±0.5 mm). Packaging available in bulk (no terminal forming) or bag packing.
• Qualification — AEC-Q200 rated, aligning the part to reliability expectations for automotive electronic use.

Typical Applications

• Switching Power Supplies — Compact footprint and low impedance make this capacitor suitable for output filtering and decoupling in switching regulators.
• Automotive Electronic Systems — AEC-Q200 rating and 5000 h endurance at 105 °C support use in vehicle electronics requiring reliable high-voltage capacitance.
• Compact Through-Hole Power Modules — Radial-lead form and small φ10 × 25 mm can enable dense board layouts where robust bulk capacitance is required.

Unique Advantages

• High-voltage bulk capacitance: 82 µF at 100 V provides substantial energy storage in a small can for high-voltage applications.
• Defined ripple performance: Specified ripple currents at 120 Hz and 10 kHz, plus low impedance, deliver predictable filtering under AC load.
• Long high-temperature endurance: Rated for 5000 hours at 105 °C, helping to extend service life in elevated-temperature environments.
• Automotive-grade qualification: AEC-Q200 rating provides a qualification baseline for vehicle electronics and other reliability-focused designs.
• Through-hole simplicity: Radial leads with 5.0 mm spacing simplify mounting and rework in prototyping and production.
• Consistent electrical characteristics: Low tanδ (0.08) and specified leakage current support stable performance in power filtering roles.
