UHE1A103MHD6

The UHE1A103MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UHE series. It is a radial-lead, polarized capacitor rated at 10 V with 10,000 µF capacitance and a -20% to +20% tolerance.

Designed for general-purpose electronic applications, this part delivers low impedance, high ripple-current capability and long-term endurance for designs that require robust bulk capacitance in a compact can-style package.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance at a 10 V rated voltage; capacitance tolerance is -20% to +20%.
• Low impedance — Rated impedance of 38 mΩ, supporting better transient response and reduced AC loss in power circuits.
• High ripple-current capability — Low-frequency ripple current 3.376 A (120 Hz) and high-frequency ripple current 4.22 A (10 kHz), enabling effective smoothing under AC/ripple loads.
• Long life and reliability — Endurance rated for 8,000 hours at 105 °C under DC bias plus rated ripple current, supporting extended operation in elevated-temperature environments.
• Wide operating temperature — Specified for -40 °C to 105 °C operation to accommodate a range of environmental conditions.
• Package and mounting — Radial lead can with dimensions φ18 × 35.5 mm and 7.5 mm lead spacing; supplied in bulk (no terminal forming) or bag packing for flexible assembly handling.
• Leakage and dissipation — Specified leakage current up to 1000 µA and tanδ (DF) of 0.37 measured at 20 °C, 120 Hz for this part configuration.
• Compliance — RoHS-compliant material and manufacturing status: mass production.

Typical Applications

• General purpose electronic circuits — Provides bulk energy storage and decoupling where a high-value polarized capacitor is required.
• Power filtering and smoothing — Handles ripple currents and reduces output ripple in DC power rails thanks to low impedance and high ripple-current ratings.
• High-reliability assemblies — Suited to designs that require long endurance at elevated temperature, with an 8,000-hour rating at 105 °C.

Unique Advantages

• Substantial bulk capacitance in a compact can — 10,000 µF in a φ18 × 35.5 mm radial package simplifies board-level bulk storage requirements.
• Low-series impedance — 38 mΩ impedance improves transient response and reduces heating under AC stress.
• High ripple tolerance across frequencies — Distinct ripple-current ratings for 120 Hz and 10 kHz support both low- and high-frequency smoothing needs.
• Engineered for extended high-temperature life — 8,000-hour endurance at 105 °C under rated conditions supports longer maintenance intervals and system uptime.
• Easy procurement and handling — Mass-production status and bulk/bag packaging options simplify volume procurement and assembly workflows.
