UPW1H181MPD6

The UPW1H181MPD6 is a radial‑lead aluminum electrolytic capacitor from Nichicon's UPW series, sized for compact power designs. It delivers 180 µF capacitance at a 50 V rating with low impedance and construction optimized for high reliability in switching power environments.

Engineered for demanding temperature and lifetime requirements, this part is rated for operation from −55°C to 105°C with a 5000 hour endurance at 105°C and carries an AEC‑Q200 rating, making it suitable for applications requiring robust performance under thermal and electrical stress.

Key Features

• Capacitance and Voltage — 180 µF nominal capacitance with a 50 V rated voltage and a tolerance of −20% to +20% at 20°C, 120 Hz.
• Low Loss / Dissipation — tan δ = 0.10 (measured at 20°C, 120 Hz) for stable performance in AC and switching environments.
• Low Impedance — specified impedance of 238 mΩ supports effective smoothing and decoupling in power rails.
• Ripple Current Capability — Low frequency ripple current of 552.5 mA at 120 Hz and high frequency ripple current of 850 mA at 10 kHz, enabling filtering across a wide frequency range.
• Leakage Current — Rated leakage current of 270 µA after one minute at rated voltage and 20°C for predictable standby behavior.
• High Temperature Endurance — 5000 hours life at 105°C under rated conditions for long-term reliability in thermal stress environments.
• Compact Radial Package — φ10 × 16 mm can with 5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assemblies; available in bulk or bag packing.
• AEC‑Q200 Rated — Meets the UPW series’ AEC‑Q200 rating for passive component reliability testing, suitable for designs requiring that qualification.

Typical Applications

• Switching Power Supplies — Low impedance and strong ripple handling make this capacitor suitable for output smoothing and bulk decoupling in switching regulators.
• DC‑DC Converters — Compact 50 V rating and 180 µF capacitance support energy storage and transient suppression in point‑of‑load converters.
• Automotive Electronics — AEC‑Q200 rating and 105°C endurance enable use in automotive control modules and power management where qualification is required.
• Industrial Power Systems — High temperature lifetime and ripple capability support filtering and buffering in industrial power assemblies.

Unique Advantages

• Space‑efficient power filtering: The φ10 × 16 mm radial can delivers 180 µF in a small footprint, helping reduce board area for compact designs.
• Wide temperature range and proven endurance: −55°C to 105°C operation with 5000 hours at 105°C provides predictable long‑term behavior in heated environments.
• Designed for switching environments: Low impedance, controlled tan δ, and frequency‑dependent ripple ratings support stable performance across 120 Hz to 10 kHz ripple spectra.
• Automotive‑grade reliability: AEC‑Q200 rating indicates the part meets established passive component qualification criteria for automotive applications.
• Through‑hole mounting simplicity: Radial lead form with 5 mm lead spacing simplifies prototype assembly and wave/flow solder processes when used in appropriate assembly flows.
