UPW2A181MHD6

The UPW2A181MHD6 is a radial‑lead aluminum electrolytic capacitor from Nichicon’s UPW series, offering a compact, low‑impedance solution for power electronics. It provides 180 µF capacitance at a 100 V rating and is designed for high‑reliability applications, including switching power supplies and automotive power systems.

Key engineering attributes include low impedance (260 mΩ), measured loss tangent (tanδ) of 0.08 at 20°C/120 Hz, high ripple current capability, and long endurance rated to 8,000 hours at 105°C, all in a φ16 × 20 mm can with 7.5 mm lead spacing.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable where higher DC voltage headroom is required.
• Low Impedance & Loss Angle — Specified impedance of 260 mΩ and tanδ of 0.08 (20°C, 120 Hz) for reduced AC voltage drop and improved performance in dynamic power rails.
• High Ripple Current Capability — Rated ripple current of 487.5 mA at 120 Hz and 750 mA at 10 kHz, supporting switching converter environments and higher frequency filtering demands.
• Long Endurance — Life rating of 8,000 hours at 105°C, designed for extended operation under elevated temperature and DC bias conditions.
• Wide Operating Temperature — Specified for −55°C to +105°C operation to accommodate a broad range of environmental conditions.
• Radial Lead Package — φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Automotive‑Grade Reliability — AEC‑Q200 rating for applications requiring industry recognized component reliability standards.
• Leakage Current — Specified leakage current of 540 µA after voltage application, useful for budgeted power loss and standby calculations.

Typical Applications

• Switching Power Supplies — Compact low‑impedance capacitance for energy buffering and stability in DC‑DC converters and SMPS designs.
• Automotive Power Electronics — AEC‑Q200 rated component for vehicle power subsystems that require 100 V capability and high endurance at elevated temperatures.
• Industrial Power Modules — Filter and bulk storage in industrial converters and control power supplies where long life and high ripple tolerance are needed.

Unique Advantages

• High‑Voltage, High‑Capacitance in a Small Footprint: 180 µF at 100 V in a φ16 × 20 mm can minimizes board area for high‑voltage energy storage.
• Designed for High‑Frequency Loading: Ripple current ratings up to 750 mA at 10 kHz and a low tanδ support demanding switching environments.
• Durability at Elevated Temperatures: 8,000‑hour endurance at 105°C provides predictable long‑term performance under sustained thermal stress.
• Automotive Reliability Standard: AEC‑Q200 rating aligns the part with reliability expectations for automotive and similarly demanding applications.
• Practical Mounting and Packaging: Radial lead form factor with 7.5 mm lead spacing and bulk/bag packing options simplify assembly and handling choices.
