UPW1H121MPD6

The UPW1H121MPD6 is a miniature, radial-lead aluminum electrolytic capacitor designed for low-impedance, high-reliability power applications. It delivers 120 µF at 50 V in a compact φ10 × 12.5 mm can optimized for applications that require robust ripple handling and long-term endurance.

Its combination of low impedance, specified ripple current ratings, wide operating temperature range and AEC‑Q200 qualification make it suitable for switching power supplies and demanding electronic systems including automotive applications.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance rated for 50 V operation with a tolerance of -20% to +20%.
• Low Loss Tangent — tanδ 0.1 (measured at 20°C, 120 Hz), supporting efficient filtering and decoupling in power circuits.
• Low Impedance — Rated impedance of 324 mΩ, helping reduce voltage ripple under dynamic load conditions.
• Ripple Current Performance — Low-frequency ripple current 403 mA (120 Hz) and high-frequency ripple current 620 mA (10 kHz) for effective power smoothing across frequencies.
• Leakage and Endurance — Specified leakage current of 180 µA and a rated life of 5000 hours at 105°C for sustained reliability.
• Robust Operating Range — Wide temperature capability from -55°C to +105°C for use in harsh environments.
• Package and Mounting — Radial lead can (φ10 × 12.5 mm) with 5 mm lead spacing; available in bulk (no terminal forming) and bag packing. Product is in mass production.
• AEC‑Q200 Rated — Qualified to AEC‑Q200, supporting use in automotive-grade and other high-reliability systems.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current capability make this capacitor suitable for output and smoothing stages in switch-mode power supplies.
• Automotive Electronic Modules — AEC‑Q200 qualification and a -55°C to +105°C operating range support use in vehicle electronics and power conditioning.
• High-Ripple Power Filtering — High-frequency ripple current rating (620 mA at 10 kHz) and low tanδ help maintain stable voltage under dynamic loads.

Unique Advantages

• Compact, high-capacitance form factor — 120 µF in a φ10 × 12.5 mm radial can saves board area while providing needed bulk capacitance.
• Improved ripple handling across frequencies — Distinct low- and high-frequency ripple current ratings enable reliable filtering from 120 Hz up through 10 kHz.
• Long-term stability at elevated temperature — 5000 hours endurance at 105°C for dependable lifetime in heated enclosures.
• Automotive-grade qualification — AEC‑Q200 rating provides an established reliability baseline for automotive and similarly demanding applications.
• Low leakage and controlled loss — 180 µA leakage and tanδ of 0.1 (20°C, 120 Hz) support efficient power delivery and minimize self-heating.
• Production-ready packaging — Available in bulk and bag packing and currently in mass production to support volume manufacturing.
