UHW1J820MPD

The UHW1J820MPD is a radial lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering a compact φ8×11.5 mm can and polarized radial-lead package. Designed for general-purpose use, it targets compact power and electronic designs that require high ripple handling and long endurance in a small footprint.

Key value comes from a combination of high ripple-current capability, a wide operating temperature range (−40°C to 105°C), and long life rating (10,000 hours at 105°C), making it suitable for space-constrained power smoothing, filtering and decoupling tasks.

Key Features

• Electrical rating — 82 µF capacitance at a rated voltage of 63 V with tolerance −20% to +20% for predictable capacitance in design.
• Low dissipation — tanδ = 0.09 (measured at 20°C, 120 Hz) to help minimize dielectric losses in AC/ripple conditions.
• High ripple current — Low-frequency ripple current of 380 mA (120 Hz) and high-frequency ripple current of 950 mA (10 kHz) to support effective smoothing under varying switching frequencies.
• Compact radial package — φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial-lead mounting for easy through-hole assembly in tight layouts; available in bulk (no terminal forming) or bag packing.
• Reliability and endurance — Rated for 10,000 hours at 105°C, with capacitance and leakage specifications maintained within the series’ endurance criteria.
• Leakage and impedance — Specified leakage current of 51.66 µA and impedance of 1.3 Ω for stable performance in DC bias and ripple conditions.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Compact power supplies — Smoothing and bulk energy storage in small form-factor linear and switching supplies where high ripple capability and small can size are required.
• Power-rail decoupling — Local decoupling and ripple suppression on intermediate or secondary power rails, leveraging the capacitor’s high-frequency ripple rating.
• Embedded and consumer electronics — General-purpose filtering in space-constrained boards that require long-term stability across −40°C to 105°C.

Unique Advantages

• Miniature footprint: φ8×11.5 mm can and radial lead form factor conserve PCB area while providing useful capacitance.
• High ripple capability: Specified 380 mA (120 Hz) and 950 mA (10 kHz) ripple currents enable reliable smoothing with switching regulators and variable-frequency sources.
• Long high-temperature life: 10,000-hour endurance at 105°C supports longer service intervals in elevated-temperature environments.
• Low dissipation factor: tanδ of 0.09 at 120 Hz reduces AC loss, improving efficiency in ripple-heavy applications.
• Through-hole robustness: Radial lead mounting and standardized 3.5 mm lead spacing simplify incorporation into prototyping and production assemblies.
• Regulatory compliance: RoHS conformity reduces material restriction risk in regional supply chains.

Why Choose UHW1J820MPD?

The UHW1J820MPD balances compact size with the ripple-handling and endurance characteristics needed for reliable power conditioning in constrained designs. Its combination of 82 µF at 63 V, low tanδ, and explicitly rated ripple currents makes it a practical choice when designers need both performance and a small through-hole footprint.

This part is well suited to engineers specifying general-purpose electrolytic capacitors for compact power supplies, decoupling on power rails, and long-life applications across a −40°C to 105°C operating range. RoHS compliance and standard radial packaging simplify integration into manufacturing and procurement processes.
