UHE1H821MHD6

The UHE1H821MHD6 is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon’s UHE series, providing 820 µF capacitance at a 50 V rating. Designed for general-purpose electronic circuits, it offers low impedance, high ripple-handling capability and long-term reliability for demanding power applications.

Its compact φ16 × 20 mm can and 7.5 mm lead spacing make it suitable for assemblies requiring high capacitance density in a radial lead form. The device is RoHS compliant and available in bulk or bag packaging for production use.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, providing substantial bulk energy storage for power rails.
• Low Impedance — Specified impedance of 100 mΩ and a tan δ of 0.10 (measured at 20°C, 120 Hz), supporting effective decoupling and filtering.
• High Ripple Current Capability — Low-frequency ripple current of 1.657 A (120 Hz) and high-frequency ripple current of 2.21 A (10 kHz), enabling stable operation under AC-biased loads.
• Long Life / High Reliability — Endurance rated for 10,000 hours at +105°C with D.C. bias plus rated ripple current applied, consistent with the UHE series’ long-life design.
• Wide Temperature Range — Operating range from −40°C to +105°C to cover a broad set of environmental conditions.
• Radial Lead Mechanical Package — φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB placement.
• Low Leakage — Specified leakage current of 410 µA at rated conditions to minimize standby losses.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• General Purpose Electronics — Bulk energy storage and smoothing for general-purpose circuits that require 820 µF at 50 V in a radial through-hole package.
• Power Supply Filtering — Filtering and ripple attenuation on DC rails where the 1.657 A (120 Hz) and 2.21 A (10 kHz) ripple ratings are needed to handle AC components.
• Decoupling & Rail Stabilization — Local decoupling for mid-power converters and regulators that benefit from low impedance (100 mΩ) and low dissipation factor.

Unique Advantages

• High Capacitance in a Compact Radial Can: 820 µF in a φ16 × 20 mm package delivers significant bulk capacitance while preserving board space for through-hole designs.
• Demonstrated Long-Term Durability: 10,000-hour endurance at 105°C under rated bias and ripple current, supporting longer service life in elevated-temperature environments.
• Robust Ripple Handling Across Frequencies: Separate ripple current specs for low (120 Hz) and high (10 kHz) frequencies let designers size bulk and high-frequency decoupling precisely.
• Predictable Low-Temperature Behavior: For the 50 V rating, impedance increases are characterized (Z(−25°C)/Z(+20°C) = 2, Z(−40°C)/Z(+20°C) = 3), allowing designers to account for cold-start performance.
• Low Leakage and Low Dissipation: Leakage current of 410 µA and tan δ = 0.10 (20°C, 120 Hz) reduce standby loss and thermal dissipation in dense power assemblies.
• Production-Friendly Packaging: Available in bulk (no terminal forming) or bag packing for streamlined procurement and handling in volume assemblies.

Why Choose UHE1H821MHD6?

The UHE1H821MHD6 balances high capacitance, low impedance and long operational life in a compact radial-through-hole package.
