UPW1V182MHD

The UPW1V182MHD is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UPW series designed for high‑reliability power applications. It provides 1800 µF capacitance at a 35 V rating in a compact φ16 × 25 mm can with 7.5 mm lead spacing.

Engineered for demanding power environments, this polarized capacitor delivers low impedance (44 mΩ), high ripple current capacity, long endurance (8,000 hours at 105 °C) and AEC‑Q200 rating for automotive and other high‑reliability markets.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) capacitance rated at 35 V with ±20% tolerance for bulk energy storage and smoothing.
• Low impedance: 44 mΩ impedance to support tight voltage regulation and reduced loss in power stages.
• High ripple handling: Rated ripple current of 2.172 A at 120 Hz and 2.555 A at 10 kHz to withstand switching and high‑frequency ripple in converters.
• Long endurance: 8,000 hours life at 105 °C under rated conditions for extended field life in thermally stressed designs.
• Wide operating temperature: −55 °C to 105 °C to cover extended environmental ranges.
• Construction & package: Radial lead, polarized aluminum can (φ16 × 25 mm) with 7.5 mm lead spacing; available in bulk or bag packing.
• Electrical loss (tan δ): tanδ 0.12 (measured at 20 °C, 120 Hz) for the 35 V rating, reflecting controlled dissipation factor.
• Leakage current: 1890 µA leakage current (specified), suitable for designs that tolerate polarized capacitor leakage at this level.
• Industry qualification: AEC‑Q200 listed in specifications for use in automotive and other qualification‑oriented projects.

Typical Applications

• Switching power supplies: Low impedance and high ripple current capability make this capacitor suitable for input/output filtering and energy buffering in switching regulators.
• Automotive electronics: AEC‑Q200 rating and wide temperature range (−55 °C to 105 °C) support use in automotive power modules and control units that require long endurance.
• DC‑DC converters and power rails: High capacitance and low ESR help stabilize transient response and reduce voltage ripple on local power rails.
• Industrial power systems: Extended life at elevated temperature (8,000 h at 105 °C) suits continuous‑duty power electronics and industrial converters.

Unique Advantages

• Compact bulk energy in a small can: 1800 µF in a φ16 × 25 mm package saves board space while providing significant smoothing capacity.
• Designed for high ripple environments: Specified ripple currents at 120 Hz (2.172 A) and 10 kHz (2.555 A) allow reliable operation in both low‑ and high‑frequency switching applications.
• Long high‑temperature life: 8,000‑hour endurance at 105 °C supports longevity in thermally demanding systems and reduces maintenance/replacement frequency.
• Automotive‑grade qualification: AEC‑Q200 rating provides confidence for use in qualification‑driven automotive and transportation designs.
• Low dissipation factor: tanδ of 0.12 at 20 °C/120 Hz for 35 V units, indicating controlled dielectric losses for stable performance.
• Polarized radial configuration: Simple radial lead mounting and standard 7.5 mm lead spacing support straightforward through‑hole assembly and prototyping.
