UHE1E821MPD

The UHE1E821MPD is a radial-lead aluminum electrolytic capacitor with 820 µF capacitance and a 25 V rated voltage. It combines a compact φ10 × 25 mm metal can package and radial leads for through-hole mounting in general-purpose electronic designs.

Designed for long-life operation and low impedance, this device supports high ripple currents and wide operating temperatures (−40 °C to 105 °C), making it suitable for demanding smoothing and decoupling roles in a variety of equipment.

Key Features

• Capacitance & Rated Voltage — 820 µF nominal capacitance at a rated voltage of 25 V, with tolerance of −20% to +20% for design margin and selection.
• Low Impedance — Specified impedance of 170 mΩ and a tan δ (loss tangent) of 0.14 measured at 20 °C, 120 Hz, supporting efficient energy storage and reduced ripple.
• High Ripple Current Capability — Low-frequency ripple current of 1.238 A (120 Hz) and high-frequency capability of 1.65 A (10 kHz), enabling effective filtering under AC ripple stress.
• Long Endurance — Rated lifetime of 7000 hours at 105 °C, providing extended service life in thermally demanding applications.
• Wide Operating Temperature — Operates from −40 °C to 105 °C to cover a broad range of environmental conditions.
• Compact Radial Package — φ10 × 25 mm can with 5 mm lead spacing and radial lead mounting for reliable through-hole installation; available in bulk or bag packing.
• Leakage & Stability — Specified leakage current of 205 µA and stable performance characteristics consistent with long-life aluminum electrolytic designs.
• RoHS Compliant — Meets RoHS requirements for material compliance.

Typical Applications

• Power supply smoothing: Bulk energy storage and output smoothing where 820 µF at 25 V and ripple handling up to 1.65 A are required.
• Decoupling and filtering: Local decoupling in general-purpose electronic assemblies that need low impedance and stable performance across −40 °C to 105 °C.
• Industrial control electronics: Applications requiring long-life capacitors able to withstand continuous ripple and elevated ambient temperatures.
• Consumer and instrumentation equipment: Through-hole mounting for serviceable boards and compact assemblies where space is constrained but higher capacitance is needed.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both low and high frequencies (1.238 A at 120 Hz, 1.65 A at 10 kHz) reduce heating and improve filtering performance under AC stress.
• Low electrical loss: Low impedance (170 mΩ) and a measured tan δ of 0.14 help minimize voltage drop and dissipation in power circuits.
• Long operational life: 7000 hours at 105 °C provides predictable service life for designs requiring durable electrolytic energy storage.
• Compact through-hole form factor: φ10 × 25 mm can and 5 mm lead spacing enable high-density placement on conventional PCBs while retaining robust leaded mounting.
• Wide ambient range: −40 °C to 105 °C operation ensures reliable behavior across common temperature extremes in industrial and commercial systems.
• RoHS compliance: Conforms to RoHS, supporting regulatory requirements for material content.
