UHW1A103MHD

The UHW1A103MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHW series, offering 10000 µF capacitance at a 10 V rated voltage. It combines a compact φ16 × 30.5 mm can with high ripple-current capability and a 10000-hour endurance rating at 105°C for sustained performance in demanding environments.

Designed for general-purpose applications, this polarized capacitor delivers low impedance, high-frequency ripple handling, and RoHS-compliant construction for use where bulk energy storage and reliable DC filtering are required.

Key Features

• Capacitance and Voltage — 10000 µF capacitance with a 10 V rated voltage and tolerance of −20% to +20%, providing large bulk storage in a small package.
• High Ripple Current — Low-frequency ripple current of 3.4 A (120 Hz) and high-frequency ripple current of 4.0 A (10 kHz), enabling effective AC stress handling on power rails.
• Low Impedance — Specified impedance of 33 mΩ supports lower voltage drop and better transient response at high currents.
• Thermal and Endurance Performance — Operating temperature range −40°C to +105°C with a rated life of 10000 hours at 105°C.
• Physical and Mounting — Radial lead can (φ16 × 30.5 mm) with 7.5 mm lead spacing (±0.5 mm), lead diameter 0.8 mm, suitable for through-hole mounting.
• Leakage and Loss — Leakage current specified at 1000 µA and tangent of loss angle (tanδ) listed at 0.36 (20°C, 120 Hz) for this part.
• Packaging and Compliance — Available in bulk (no terminal forming) or bag packing; RoHS compliant.

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in power supply circuits where compact, high-capacitance radial electrolytics are required.
• Power rail decoupling — Supports high ripple current demands on DC rails in industrial and consumer electronic equipment.
• High-frequency ripple environments — Designed to handle ripple up to 10 kHz with specified high-frequency ripple current values.

Unique Advantages

• High-capacitance density — 10000 µF in a φ16 × 30.5 mm can enables significant bulk storage in space-constrained designs.
• Proven thermal endurance — 10000-hour lifetime at 105°C supports long-term reliability under elevated operating temperatures.
• Robust ripple handling — Rated ripple currents of 3.4 A (120 Hz) and 4.0 A (10 kHz) address both low- and high-frequency AC stress on power systems.
• Low impedance — 33 mΩ impedance improves voltage stability and transient performance in high-current circuits.
• Through-hole robustness — Radial lead construction with defined lead spacing simplifies board-level mounting and mechanical retention.
• Regulatory compliance — RoHS-compliant construction for use in regulated supply chains.
