UPW2A6R8MDD

The UPW2A6R8MDD is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon’s UPW series, designed for low‑impedance applications such as switching power supplies. This polarized, radial‑lead component delivers 6.8 µF of capacitance at a 100 V rating in a compact φ5 × 11 mm can, targeting compact power modules and automotive electronics that require a robust, high‑voltage decoupling solution.

Key Features

• Capacitance & Voltage — 6.8 µF rated capacitance with a 100 V rated voltage, suitable for higher‑voltage rails within compact power designs.
• Low impedance / loss — Specified tanδ of 0.08 (measured at 20°C, 120 Hz) for lower AC loss and improved performance in high‑frequency environments.
• Ripple and leakage characteristics — Low‑frequency ripple current of 28.5 mA (120 Hz) and high‑frequency ripple current of 95 mA (10 kHz), with a leakage current of 20.4 µA.
• High reliability & endurance — Life/endurance rating of 2000 hours at 105°C and AEC‑Q200 qualification for stress‑test reliability in demanding applications.
• Wide operating temperature — Operating range from −55°C to +105°C for stable performance across automotive and industrial temperature extremes.
• Compact radial package — φ5 × 11 mm can, radial lead mounting with 2 mm lead spacing (±0.5 mm), available in bulk or bag packing for flexible assembly workflows.

Typical Applications

• Switching power supplies — Low impedance and compact size make this capacitor suitable for output filtering and smoothing in compact switching regulators.
• Automotive electronics — AEC‑Q200 qualification and −55°C to +105°C operating range support use in vehicle control modules and power electronics.
• Compact power modules — Small φ5 × 11 mm footprint and radial lead form factor enable high‑density board layouts and space‑constrained designs.

Unique Advantages

• High‑voltage capability: 100 V rating provides headroom for higher‑voltage rails without increasing capacitor size significantly.
• Designed for low AC loss: tanδ = 0.08 at 20°C/120 Hz supports improved efficiency in AC and switching environments.
• Automotive‑grade reliability: AEC‑Q200 rating and 2000 h endurance at 105°C address long‑term reliability requirements.
• Measured ripple performance: Specified ripple current ratings at both low and high frequencies (120 Hz / 10 kHz) enable predictable thermal and lifetime planning.
• Space‑saving form factor: φ5 × 11 mm can and 2 mm lead spacing simplify integration into dense PCBs and compact modules.
