UHE2A821MHD

The UHE2A821MHD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UHE series, configured as a radial lead can. It delivers 820 µF capacitance at a 100 V rating with a low-impedance design and long endurance for general-purpose power electronics.

Designed for engineers and procurement teams working on general-purpose power and smoothing applications, this capacitor combines a compact φ18 × 40 mm package with high-frequency ripple capability and extended life performance up to 10,000 hours at 105°C.

Key Features

• Capacitance & Voltage: 820 µF capacitance with a 100 V rated voltage, suitable for higher-voltage general-purpose designs.
• Low Impedance: Specified impedance of 130 mΩ and a loss tangent (tanδ) of 0.08 (measured at 20°C, 120 Hz), supporting stable decoupling and filter performance.
• High Ripple Current Capability: Low-frequency ripple current of 1.853 A at 120 Hz and high-frequency ripple current of 2.47 A at 10 kHz, enabling effective ripple handling across a range of frequencies.
• Long Endurance: Rated for 10,000 hours at 105°C (for 16–100 V range) as part of the UHE series endurance specification, supporting reliable long-term operation.
• Wide Operating Temperature: Operational range from −40°C to 105°C, suitable for many industrial and commercial environments.
• Radial Lead, Compact Package: φ18 × 40 mm can with 7.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole PCB designs; available in bulk or bag packing.
• Leakage & Tolerance: Leakage current specified at 820 µA and capacitance tolerance of −20% to +20%.
• RoHS Compliant: Meets RoHS directive requirements as indicated for the UHE series.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple smoothing for power supplies and power rails in general-purpose electronic equipment.
• Energy storage and decoupling — Useful where 820 µF at 100 V is needed to stabilize voltage and supply transient currents in through-hole designs.
• Industrial control electronics — Suitable for control systems that require robust, long-life capacitors rated to 105°C for continuous operation.

Unique Advantages

• High voltage capability: 100 V rating enables use in higher-voltage circuits without series stacking or complex design workarounds.
• Extended lifetime: 10,000-hour endurance at 105°C for 16–100 V parts in the UHE series supports long-term reliability in demanding environments.
• Broad ripple performance: Rated ripple currents at both low (120 Hz) and high (10 kHz) frequencies allow consistent performance across switching and linear power systems.
• Compact radial package: φ18 × 40 mm can and standard 7.5 mm lead spacing simplify replacement and integration into through-hole PCBs.
• Low-loss operation: tanδ = 0.08 at 100 V (120 Hz, 20°C) and low impedance (130 mΩ) contribute to efficient energy handling and reduced heating in service.
• Regulatory compliance: RoHS compliance supports deployment in regions and products requiring restricted substance adherence.
