UHE2A121MHD6

The UHE2A121MHD6 is a miniature aluminum electrolytic capacitor from Nichicon’s UHE series. It is a radial-lead, polarized capacitor with a 120 µF capacitance and a 100 V rated voltage, designed for general-purpose electronic circuits that require compact energy storage and smoothing.

Built for low impedance and long-term reliability, this UHE-series part offers a combination of measurable low-loss characteristics and extended endurance, making it suitable for designs operating across a broad temperature range.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 100 V rated voltage and a capacitance tolerance of −20% to +20%.
• Low Impedance & Low Loss — Specified impedance of 640 mΩ and tangent of loss angle (tanδ) of 0.08 at 20°C, 120 Hz, supporting effective filtering and decoupling.
• Ripple Current Handling — Low-frequency ripple current of 535.5 mA at 120 Hz and high-frequency ripple current of 765 mA at 10 kHz, enabling reliable performance under AC ripple stress.
• Long Life & Wide Temperature Range — Endurance rated for 10,000 hours at 105°C and an operating temperature range from −40°C to +105°C.
• Package & Mounting — Radial lead, can-type package sized φ12.5 × 20 mm with 5 mm lead spacing (±0.5 mm), suitable for through-hole PCB mounting.
• Leakage & Stability — Leakage current specified at 120 µA; capacitance stability and loss characteristics provided per UHE series specifications.
• Packaging & Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Provides smoothing and energy storage where a 100 V, 120 µF polarized capacitor is required.
• Power supply filtering — Low impedance and specified ripple current ratings support filtering and ripple attenuation in DC power rails.
• Industrial and control electronics — Endurance of 10,000 hours at 105°C and wide operating temperature range suit continuous-operation systems.

Unique Advantages

• Measurable low-loss performance: tanδ = 0.08 at 20°C/120 Hz and 640 mΩ impedance help maintain stable filtering and reduce heat generation in circuits.
• High voltage capability: 100 V rating enables use in higher-voltage DC circuits where greater voltage margin is required.
• Extended endurance: 10,000-hour life at 105°C supports long-term reliability in sustained high-temperature environments.
• Compact radial package: φ12.5 × 20 mm can with 5 mm lead spacing provides a space-efficient through-hole solution for PCB designs.
• Clear specification set: Defined ripple currents, leakage current, and tolerance allow straightforward selection and thermal/ripple budgeting during design.
• RoHS compliant: Meets environmental directive requirements for restricted substances.
