UHE0J103MHD

The UHE0J103MHD is a Nichicon UHE-series miniature aluminum electrolytic capacitor in a radial‑lead can. It delivers 10,000 µF capacitance at a rated voltage of 6.3 V with a compact φ16 × 35.5 mm package and 7.5 mm lead spacing.

Designed for general‑purpose use, this high‑reliability part combines low impedance, high ripple current capability and extended endurance — offering reliable bulk energy storage and smoothing in applications that require long life up to 8000 hours at 105°C.

Key Features

• Capacitance & Rated Voltage — 10,000 µF (10 mF) nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%.
• Low impedance — Typical impedance of 44 mΩ, supporting low loss and effective smoothing in power applications.
• High ripple current capability — Low‑frequency ripple current of 2.888 A at 120 Hz and high‑frequency ripple current of 3.61 A at 10 kHz, enabling robust handling of AC components on DC rails.
• Long endurance — Rated for 8000 hours at 105°C (when used within specified conditions), supporting extended service life in elevated temperatures.
• Wide operating temperature range — Specified for −40°C to +105°C operation; impedance characteristics at low temperature are defined (Z(−25°C)/Z(+20°C) = 4 and Z(−40°C)/Z(+20°C) = 8 for 6.3 V units).
• Leakage and dissipation — Leakage current specified at 630 µA; tangent of loss angle (tan δ) = 0.40 (measured at 20°C, 120 Hz for this capacitance/voltage).
• Package and mounting — Radial lead, can style package (φ16 × 35.5 mm) with 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General purpose electronics: For designs that require a 10,000 µF, 6.3 V radial‑lead aluminum electrolytic capacitor with low impedance and long life.
• Power rail smoothing: Where bulk capacitance and defined ripple current handling are needed to stabilize DC rails within −40°C to +105°C operating range.
• High‑reliability assemblies: Suitable for equipment that benefits from extended endurance (8000 hours at 105°C) and defined leakage/tan δ characteristics.

Unique Advantages

• Large capacitance in a compact can: 10,000 µF in a φ16 × 35.5 mm radial package provides substantial bulk energy storage while conserving board area.
• Measurable low impedance: 44 mΩ impedance supports reduced ripple voltage and improved transient response on power rails.
• Defined ripple performance: Rated ripple currents specified at both low and high frequencies (120 Hz and 10 kHz), enabling predictable thermal and lifetime performance.
• Extended high‑temperature life: 8000 hours at 105°C for 6.3 V ratings gives predictable longevity for elevated‑temperature deployments.
• Clear low‑temperature behavior: Provided impedance ratios for −25°C and −40°C help assess performance in cold environments.
• Regulatory compliance: RoHS compliance supports use in assemblies requiring restricted‑substance adherence.
