UHW1V821MPD

The UHW1V821MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose applications. It delivers 820 µF capacitance at a 35 V rating in a compact φ10 × 25 mm package with 5.0 mm lead spacing.

Engineered for compact designs that require elevated ripple current handling and long-term endurance, this capacitor combines low impedance (51 mΩ) and low loss (tanδ 0.11 at 35 V, 120 Hz, 20°C) with a rated lifetime of 10,000 hours at 105°C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 35 V and tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current of 1.74 A (120 Hz) and high-frequency ripple current of 2.9 A (10 kHz), suitable for circuits with significant ripple demands.
• Low Impedance & Low Loss — Impedance of 51 mΩ and tangent of loss angle (tanδ) of 0.11 at 120 Hz (35 V, 20°C) for improved AC performance.
• Reliability & Endurance — Rated for 10,000 hours at 105°C under endurance conditions, supporting long-term operation in elevated-temperature environments.
• Operating Temperature Range — Specified for −40°C to +105°C to cover a wide range of environmental conditions.
• Package & Mounting — Radial lead can, size φ10 × 25 mm, lead spacing 5.0 mm (±0.5 mm), available in bulk or bag packing; mass-production status.
• Leakage Current — Specified leakage current of 287 µA after application of rated voltage, supporting predictable quiescent behavior.
• RoHS Compliant — Meets RoHS requirements as stated in the product data.

Typical Applications

• General Purpose — For broad general-purpose use where an 820 µF, 35 V electrolytic capacitor is required in a compact radial-lead form.
• High-Ripple Circuits — Applicable in circuits that require elevated ripple handling, leveraging 1.74 A (120 Hz) and 2.9 A (10 kHz) ripple current ratings.
• Compact Power Modules — Suitable for board-level use where space is limited, using the φ10 × 25 mm can and 5.0 mm lead spacing for through-hole mounting.

Unique Advantages

• High ripple-current capability: Measurable ripple ratings at both low and high frequency (1.74 A at 120 Hz, 2.9 A at 10 kHz) reduce heating and improve reliability under AC stress.
• Low impedance and low loss: 51 mΩ impedance and tanδ 0.11 (35 V, 120 Hz, 20°C) support better filtering and stability in power circuits.
• Long endurance at elevated temperature: 10,000-hour rated lifetime at 105°C provides predictable service life for sustained thermal environments.
• Compact radial-lead package: φ10 × 25 mm can with 5.0 mm lead spacing enables compact through-hole layouts without sacrificing capacitance.
• Predictable leakage behavior: Specified leakage current (287 µA) helps designers budget quiescent currents accurately.
• Production-ready availability: Mass production status and standard packaging options (bulk and bag) simplify procurement and assembly planning.
