UHW1C821MPD

The UHW1C821MPD is a radial-lead, polarized aluminum electrolytic capacitor offering 820 µF capacitance at a 16 V rating. It combines a compact φ10×16 mm can with high ripple-current capability and low impedance to support general-purpose power applications.

Designed for high-reliability use, this RoHS-compliant capacitor delivers long endurance (10000 hours at 105°C), broad operating temperature range (−40°C to 105°C) and packaging options for bulk or bag supply, making it suited to production designs requiring compact bulk capacitance with robust thermal and ripple performance.

Key Features

• Capacitance & Voltage — 820 µF at 16 V with tolerance of −20% to +20%, providing predictable bulk energy storage for power rails.
• High Ripple Current — Rated for 1.2 A at 120 Hz and 2.0 A at 10 kHz, enabling effective handling of both low- and high-frequency ripple in power systems.
• Low Impedance — Specified impedance of 90 mΩ supports lower voltage drop and improved smoothing performance at operating frequencies.
• Thermal and Lifetime Performance — Rated for continuous operation from −40°C to 105°C with an endurance of 10000 hours at 105°C under rated conditions.
• Electrical Quality — Loss tangent (tanδ) of 0.15 measured at 20°C, 120 Hz, and leakage current specified at 131.2 µA, supporting stable behavior in DC-biased circuits.
• Compact Radial Package — φ10×16L can with 5 mm lead spacing (±0.5 mm) and radial lead mounting simplifies assembly for through-hole boards; available in bulk (no terminal forming) or bag packing for production lines.
• Regulatory — Compliant with RoHS requirements.

Typical Applications

• Power-supply filtering and smoothing — High ripple-current rating and low impedance provide reliable bulk capacitance for smoothing DC rails and reducing ripple.
• DC/DC converter output stages — Compact size and high-frequency ripple capability support output decoupling in compact converter designs.
• Industrial and consumer power modules — Wide temperature range (−40°C to 105°C) and long endurance make it suitable for general-purpose power sections in industrial and consumer equipment.

Unique Advantages

• High ripple-handling capacity: 2.0 A at 10 kHz and 1.2 A at 120 Hz lets designs tolerate significant AC stress on DC rails without oversized components.
• Compact footprint: φ10×16 mm can delivers 820 µF capacitance in a small radial package to save board area while retaining through-hole robustness.
• Long-term reliability: 10000 hours endurance at 105°C supports sustained operation in thermally demanding installations.
• Stable electrical characteristics: Specified tanδ and low leakage current provide predictable performance for designers managing loss and standby currents.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing for flexible handling on assembly lines.
