UHW1A122MPD6

The UHW1A122MPD6 is a Nichicon UHW series radial lead aluminum electrolytic capacitor offering 1.2 mF (1200 µF) capacitance at a 10 V rating. It combines a miniature φ8 × 20 mm can with high ripple current capability and low impedance characteristics specified for the UHW series.

Designed for general-purpose electronic applications, this component delivers a compact footprint, a wide operating temperature range of −40 °C to 105 °C, and a rated endurance of 10,000 hours at 105 °C for designs that require long-term stability in demanding environments.

Key Features

• Electrical Performance — Capacitance 1.2 mF (1200 µF) with tolerance ±20% and rated voltage of 10 V; impedance specified at 120 mΩ for quick assessment of AC performance.
• Low Loss (tan δ) — Tangent of loss angle (tan δ) listed as 0.18 measured at 20 °C, 120 Hz, enabling predictable dissipation characteristics for AC and ripple environments.
• High Ripple Current Capability — Low-frequency ripple current of 1.176 A at 120 Hz and high-frequency ripple current of 1.96 A at 10 kHz to support applications with significant AC ripple content.
• Leakage and Endurance — Specified leakage current of 120 µA and life/endurance rating of 10,000 hours at 105 °C under the UHW series endurance conditions.
• Compact Radial Package — φ8 × 20 mm can, radial lead mounting with 3.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB assemblies where a small footprint is required.
• Environmental Compliance — RoHS compliant, meeting current restricted-substance requirements.
• Packaging and Production Status — Available in bulk (no terminal forming) or bag packing; product is in mass production.

Typical Applications

• General-Purpose Electronics — Compact, board-level energy storage and decoupling in designs that require a 1.2 mF, 10 V radial electrolytic solution with high ripple capability.
• High-Ripple Circuits — Use where elevated ripple currents occur; the part’s specified low- and high-frequency ripple ratings support reliable operation under AC-loaded conditions.
• Long-Life Assemblies — Suitable for applications that demand extended operation at elevated temperature, backed by a 10,000-hour rating at 105 °C.

Unique Advantages

• Compact high-capacitance in a small can — 1.2 mF in a φ8 × 20 mm package lets designers save board space without sacrificing storage capacity.
• Measured low impedance — 120 mΩ impedance specification gives a clear indicator of AC performance for filtering and decoupling design decisions.
• Dual-frequency ripple ratings — Rated ripple current at both 120 Hz and 10 kHz provides quantified performance for designers addressing low- and high-frequency ripple sources.
• Long endurance at temperature — 10,000-hour life at 105 °C supports designs that require predictable long-term behavior under thermal stress.
• Radial-lead, through-hole convenience — 3.5 mm lead spacing and standard radial mounting simplify assembly in through-hole designs and retrofit scenarios.
• Regulatory compliance — RoHS compliance supports use in regulated product environments.
