UPW1H121MPD

The UPW1H121MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, designed for miniature, low-impedance, high-reliability power applications. It delivers 120 µF capacitance at a 50 V rating in a compact φ8 × 15 mm can with 3.5 mm lead spacing.

Targeted at power supply and board-level filtering uses, the UPW1H121MPD offers measurable ripple handling, long endurance at elevated temperature, and AEC‑Q200 qualification for automotive applications.

Key Features

• Capacitance and Tolerance — 120 µF nominal capacitance with tolerance of −20% to +20% (measured at 20°C, 120 Hz).
• Rated Voltage — 50 V DC rated voltage for mid-voltage power rails.
• Low Loss Characteristics — tanδ (DF) 0.1 measured at 20°C, 120 Hz, supporting stable performance in AC ripple environments.
• Impedance — 310 mΩ impedance for reduced voltage ripple under load.
• Ripple Current Ratings — 412.8 mA at 120 Hz (low frequency) and 635 mA at 10 kHz (high frequency), providing frequency-aware ripple capability.
• Leakage Current — 180 µA specified leakage current after application of rated voltage at 20°C.
• High-Temperature Endurance — 3000 hours life rating at 105°C with DC bias plus rated ripple current.
• Package and Mounting — Radial lead, polarized aluminum can (φ8 × 15L) with 3.5 mm lead spacing and pressure relief vent; available in bulk (no terminal forming) or bag packing.
• Automotive Grade — AEC‑Q200 rating included in product specifications for automotive suitability where specified.
• Operating Temperature Range — −55°C to +105°C, suitable for a wide range of ambient conditions.

Typical Applications

• Switching Power Supplies — Designed for miniature, low-impedance filtering in switching power supply outputs and snubber networks.
• Automotive Electronics — AEC‑Q200 rating and extended temperature endurance make it appropriate for vehicle power modules and control electronics.
• Board-Level Power Filtering — Compact radial can and defined ripple current specs support bulk decoupling and smoothing on PCB power rails.

Unique Advantages

• Measured Low Impedance — 310 mΩ impedance contributes to improved ripple voltage attenuation compared to higher-impedance alternatives.
• Frequency-Aware Ripple Performance — Specified ripple currents at 120 Hz and 10 kHz give clear guidance for both low- and high-frequency filtering needs.
• Compact, Board-Friendly Form — φ8 × 15 mm radial can with 3.5 mm lead spacing saves board area while keeping through-hole mounting simplicity.
• Proven High-Temperature Endurance — 3000 hours at 105°C under bias supports long-term reliability in elevated-temperature environments.
• Automotive-Grade Reliability — Inclusion of AEC‑Q200 in the product data supports use in automotive system designs where that qualification is required.
• Flexible Packaging Options — Available in bulk (no terminal forming) or bag packing to match production handling and assembly workflows.
