• Low Impedance — Specified impedance of 42 mΩ, supporting effective decoupling and energy storage in compact power designs.
• High Ripple Current Capability — Low-frequency ripple current of 870.4 mA (120 Hz) and high-frequency ripple current of 1.28 A (200 kHz) for handling both bulk and switching ripple components.
• Electrical Losses — Dissipation factor (tan δ) of 0.12 measured at 20°C and 120 Hz, providing predictable AC loss behavior.
• Leakage Current — Specified leakage current of 714 µA, enabling controlled standby loss characteristics.
• High Reliability & Endurance — Rated for 5000 hours at 105°C under load, meeting the UPM series’ long-life criteria for continuous operation at elevated temperature.
• Temperature Range — Operating range from –55°C to +105°C for a wide variety of environmental conditions.
• Package & Mounting — Radial-lead, polarized aluminum can in a compact φ18 × 15 mm footprint with 7.5 mm lead spacing; available in bulk or bag packing.
• Compliance & Qualification — RoHS-compliant and AEC-Q200 qualified for applications requiring automotive-grade component qualification.

Typical Applications

• Automotive Power Filtering — Bulk and decoupling capacitor for automotive power rails and electronic control modules, leveraging AEC-Q200 qualification and high-temperature endurance.
• DC–DC Converter Output — Output smoothing for switching regulators where low impedance and high ripple current capability reduce voltage ripple and heat rise.
• Industrial Control Electronics — Power rail stabilization in industrial controllers and driver boards operating across –55°C to +105°C.
• Sensor and Actuator Power — Local energy reservoir for sensors, actuators, and peripheral subsystems that demand reliable performance under temperature stress.

Unique Advantages

• Proven Endurance: 5000-hour rated life at 105°C gives designers a measurable reliability baseline for long-term deployments.
• High Ripple Handling: Combined low- and high-frequency ripple current specifications (870.4 mA at 120 Hz and 1.28 A at 200 kHz) support mixed-frequency power systems.
• Compact, Serviceable Form Factor: φ18 × 15 mm radial can with 7.5 mm lead spacing enables easy through-hole mounting and replacement in constrained assemblies.
• Automotive-Grade Qualification: AEC-Q200 qualification and a wide operating temperature range make it suitable for rigorous automotive and industrial environments.
• Predictable Electrical Performance: Low impedance (42 mΩ) and defined tan δ (0.12 at 20°C/120 Hz) allow accurate thermal and ripple-loss budgeting in designs.
• Regulatory Compliance: RoHS compliance supports environmental and supply-chain requirements.
