UHD1E821MPD

The UHD1E821MPD is a Nichicon UHD series aluminum electrolytic capacitor in a radial‑lead can optimized for high ripple handling and low impedance at higher frequencies. It is a polarized, general‑purpose component intended for power filtering, bulk energy storage and decoupling in electronic designs that require a compact, high‑capacitance solution.

Key value comes from its combination of 820 µF capacitance, 25 V rated voltage, compact φ10 × 25 mm case and specified ripple current performance across low and high frequencies, enabling reliable operation over a −40 °C to +105 °C range with a 4000‑hour endurance at 105 °C.

Key Features

• Capacitance & Voltage — 820 µF capacitance at a rated voltage of 25 V with ±20% tolerance, suitable for bulk filtering and energy storage in general‑purpose designs.
• Low‑loss Electrical Performance — Tangent of loss angle (tan δ) of 0.14 measured at 20 °C, 120 Hz, supporting efficient AC performance in filtering applications.
• High Ripple Current Capability — Rated low‑frequency ripple current of 1612.5 mA at 120 Hz and high‑frequency ripple current of 2150 mA at 100 kHz, enabling improved ripple handling in power circuits.
• Leakage Current — Specified leakage current of 205 µA after two minutes at 20 °C, aiding predictable bias behavior in DC circuits.
• Thermal and Endurance Specification — Operating temperature range −40 °C to +105 °C and endurance of 4000 hours at 105 °C under rated conditions.
• Form Factor & Mounting — Radial lead mounting in a φ10 × 25 mm can with 5 mm lead spacing (±0.5 mm tolerance); leaded, polarized package for through‑hole assembly.
• Compliance & Availability — RoHS‑compliant and in mass production; packaged in bulk (no terminal forming) or bag packing.

Typical Applications

• General‑purpose power filtering — Bulk smoothing and ripple reduction in power supplies where 25 V rating and 820 µF capacitance are required.
• DC bus and decoupling — Local energy reservoir and decoupling for moderate ripple currents up to specified low and high frequency limits.
• Industrial and consumer electronics — General‑purpose use in assemblies that require a compact radial electrolytic with defined endurance at elevated temperature.

Unique Advantages

• High ripple handling in a small can — Delivers 1.6125 A at 120 Hz and 2.15 A at 100 kHz from a φ10 × 25 mm package, enabling compact board layouts without sacrificing ripple capability.
• Low impedance at higher frequencies — UHD series design characteristics reduce impedance at high frequency, improving filtering performance where high‑frequency ripple is present.
• Wide operating temperature and proven endurance — Rated for −40 °C to +105 °C with 4000 hours endurance at 105 °C for predictable long‑term performance under elevated temperature stress.
• Predictable electrical behavior — Specified tan δ (0.14 at 20 °C, 120 Hz) and defined leakage current (205 µA) make circuit bias and loss budgeting straightforward.
• RoHS compliant and production ready — Meets RoHS requirements and is available in mass production with bulk or bag packaging for assembly flexibility.
