UPW2F101MRD6

The UPW2F101MRD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series designed for low-impedance power applications. It is a radial-lead, polarized capacitor specified at 100 µF and 315 V, optimized for use in switching power supplies and automotive power electronics where sustained performance at elevated temperature and ripple conditions is required.

Key Features

• Capacitance & Voltage — 100 µF rated capacitance with a 315 V DC rating and a capacitance tolerance of -20% to +20%.
• Low-loss Performance — Tangent of loss angle (tan δ) 0.2 measured at 20°C and 120 Hz, supporting stable behavior under AC excitation.
• Ripple Current Handling — Low-frequency ripple current 285 mA at 120 Hz and high-frequency ripple current 456 mA at 10 kHz to accommodate switching ripple in power converters.
• Leakage Current — Specified leakage current of 1,360 µA after application of rated voltage, useful for designing bias and standby conditions.
• High Temperature Endurance — Rated for operation from -40°C to +105°C with an endurance/lifetime of 8,000 hours at 105°C.
• Package & Mounting — Radial, can-style package (φ20 × 35 mm) with 10 mm lead spacing (±0.5 mm) for through-hole mounting and robust mechanical retention.
• AEC Qualification — AEC-Q200 rating for designs requiring recognized reliability standards in demanding environments.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit assembly and storage needs.

Typical Applications

• Automotive Power Electronics — Energy storage and smoothing on high-voltage rails in automotive systems where AEC-Q200 qualification and high-temperature endurance are required.
• Switching Power Supplies — Low-impedance filtering and decoupling for SMPS where the series’ miniature, low-impedance characteristics are beneficial.
• High-Voltage DC Filtering — Bulk and ripple filtering on 315 V DC rails for industrial or commercial power modules.

Unique Advantages

• High Voltage Capability: 315 V rating enables use on elevated DC rails without requiring multiple lower-voltage capacitors in series.
• Compact, Through-Hole Form Factor: φ20 × 35 mm can-style body with radial leads and 10 mm spacing provides a space-efficient solution for board-level power filtering while maintaining mechanical strength.
• Designed for Switching Environments: Low impedance and specified high-frequency ripple current (456 mA at 10 kHz) address the needs of switching regulators and converters.
• Long-Term Thermal Reliability: 8,000-hour endurance at 105°C supports sustained operation in high-temperature ambient conditions.
• Automotive-Grade Reliability: AEC-Q200 rating provides a qualification baseline suitable for automotive and other demanding applications.
