UPW2A101MHD

The UPW2A101MHD is a radial-lead aluminum electrolytic capacitor offering 100 µF capacitance at a 100 V rating in a compact φ12.5 × 20 mm can. It is designed for low impedance and long-term reliability in power applications, with an extended endurance rating of 7000 hours at 105°C.

Targeted uses include switching power supplies and power-dense electronic modules where compact size, high voltage handling and robust ripple performance are required. The part combines measurable low impedance, defined ripple-current capability and an automotive AEC-Q200 rating for demanding environments.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable for high-voltage filtering and energy storage in compact assemblies.
• Low Impedance — Specified impedance of 360 mΩ and tanδ 0.08 (measured at 20°C, 120 Hz), providing reduced ripple voltage in power rails.
• Ripple Current Capability — Rated ripple current of 377 mA at 120 Hz and 580 mA at 10 kHz, enabling reliable handling of both low- and high-frequency ripple in switching supplies.
• Long Endurance at Elevated Temperature — Life rating of 7000 hours at 105°C under rated bias plus ripple current, supporting prolonged operation in thermally stressed systems.
• Wide Operating Temperature Range — Operates from −55°C to +105°C to cover a broad set of environmental conditions.
• Compact Radial Package — φ12.5 × 20 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies and easy board placement.
• Leakage Current — Specified leakage current of 300 µA, useful for design margining in power-hold and standby circuits.
• AEC-Q200 Rated — Automotive-oriented qualification indicated in the product data, supporting use in demanding vehicle electronics and related applications.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing and listed as in mass production.

Typical Applications

• Switching Power Supplies — Bulk and output filtering for DC‑DC converters, leveraging low impedance and defined ripple-current specs to reduce output ripple and heat.
• Automotive Power Modules — Energy storage and smoothing in vehicle electronics where AEC-Q200 qualification and high-temperature endurance are required.
• Industrial Power Electronics — Filtering and decoupling in industrial converters and motor-drive electronics operating across wide temperature ranges.
• High-Voltage DC Circuits — Applications requiring 100 V rated capacitors in a compact radial form for board-level energy buffering and transient suppression.

Unique Advantages

• Proven High-Temperature Durability: 7000 hours endurance at 105°C under rated conditions provides predictable lifetime behavior in hot enclosures.
• Low-Impedance Performance: 360 mΩ impedance and tanδ of 0.08 at 20°C/120 Hz reduce ESR-related losses and improve voltage stability under load.
• Frequency-Resilient Ripple Handling: Separate ripple-current specs for 120 Hz (377 mA) and 10 kHz (580 mA) clarify performance across switching frequencies.
• Compact Through-Hole Form Factor: φ12.5 × 20 mm radial can with 5 mm lead spacing simplifies retrofits and through-hole board designs without sacrificing rated voltage.
• Automotive-Grade Qualification: AEC‑Q200 listing supports deployment in vehicle electronics and other demanding systems requiring higher reliability.
• Clear Leakage and Loss Metrics: 300 µA leakage and defined tanδ measurement conditions (20°C, 120 Hz) make it easier to model standby and AC-loss behavior.
