UHW1C821MPD6

The UHW1C821MPD6 is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can. It provides 820 µF capacitance at 16 V with a compact φ8×20 mm package and is designed for general-purpose electronic circuits that require high ripple-current capability and long operating life.

Key design attributes include low impedance, high ripple current handling across a broad frequency range, and extended endurance at elevated temperature, making it suitable for assemblies where space, reliability and power decoupling are important.

Key Features

• Capacitance and Voltage: 820 µF nominal capacitance rated at 16 V with capacitance tolerance of −20% to +20%.
• Miniature Radial Package: φ8×20 mm can with radial lead mounting, 3.5 mm lead spacing (±0.5 mm) for compact PCB layouts.
• High Ripple-Current Performance: Low-frequency ripple current 1.176 A at 120 Hz and high-frequency ripple current 1.96 A at 10 kHz, supported by the UHW series’ low impedance (120 mΩ).
• Electrical Losses: Tangent of loss angle (tan δ) of 0.15 at 120 Hz, 20°C (rated voltage 16 V) for predictable dissipation characteristics.
• Leakage Current: Specified leakage current of 131.2 µA under rated conditions, supporting stable idle performance.
• Wide Temperature and Long Endurance: Operating range −40°C to +105°C with an endurance/lifetime rating of 10,000 hours at 105°C.
• Compliance and Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible assembly handling.

Typical Applications

• General-purpose power filtering: Bulk and decoupling in power rails where compact size and sustained ripple-current capability are required.
• High-ripple current modules: Use in small power modules and converters that demand low impedance and reliable ripple-current handling at both low and high frequencies.
• Space-constrained assemblies: Circuit boards that require a miniature radial electrolytic with verified endurance at elevated temperature.

Unique Advantages

• Compact, serviceable form factor: φ8×20 mm radial can with 3.5 mm lead spacing reduces board area while remaining through-hole serviceable.
• Measured ripple capability: Specified ripple currents at 120 Hz and 10 kHz give designers quantifiable margins for both low- and high-frequency applications.
• Predictable loss characteristics: Specified tan δ and impedance enable accurate thermal and ESR budgeting in power designs.
• Extended operating life: 10,000-hour endurance at 105°C supports long-term reliability in elevated-temperature environments.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted substance conformance.
