UHD1A122MPD

The UHD1A122MPD is a radial-lead aluminum electrolytic capacitor offering 1200 µF capacitance at a 10 V rating in a compact φ10×20 mm can. It is a polarized, general-purpose device designed for circuits that demand high ripple-current capability and low impedance across higher frequencies.

Built for robust operation across a wide temperature range (−40°C to +105°C) with a 4000 h endurance at 105°C, the UHD1A122MPD targets electronic designs where compact size, ripple handling and long-term reliability are important.

Key Features

• Capacitance & Voltage — 1200 µF rated capacitance at 10 V with ±20% tolerance, suitable for bulk energy storage and smoothing in compact circuits.
• High ripple-current capability — Low-frequency ripple current of 1.456 A (120 Hz) and high-frequency ripple current of 1.82 A (100 kHz) to support demanding AC ripple conditions.
• Low impedance at high frequency — Series UHD characteristic of lower impedance in the high-frequency range for improved filtering and decoupling performance.
• Physical package — Radial-lead can, φ10×20 mm (L = 20 mm) with 5.0 mm lead spacing (±0.5 mm) and typical lead diameter 0.6 mm for straightforward through-hole mounting.
• Electrical loss — Dissipation factor (tan δ) specified as 0.19 (measured at 20°C, 120 Hz), supporting predictable AC behavior.
• Leakage and endurance — Leakage current 120 µA (after 2 minutes at 20°C) and endurance of 4000 hours at 105°C under rated voltage plus ripple current.
• Environmental compliance & packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing. Mass production status.

Typical Applications

• General-purpose electronics — Suitable for a wide range of electronic circuits that require polarized bulk capacitance with reliable performance across −40°C to +105°C.
• Power filtering and smoothing — High ripple-current ratings and low high-frequency impedance make it appropriate for smoothing DC rails and suppressing ripple in compact power designs.
• Decoupling in higher-frequency circuits — Low impedance at higher frequencies and specified tan δ provide predictable decoupling behavior for power electronics and control modules.

Unique Advantages

• High ripple tolerance: Specified 1.456 A at 120 Hz and 1.82 A at 100 kHz enables reliable operation under significant AC stress.
• Compact radial can: φ10×20 mm footprint and 5 mm lead spacing provide a small, easy-to-place solution for through-hole assemblies.
• Long high-temperature endurance: 4000 hours at 105°C supports durable operation in thermally demanding environments.
• Predictable loss characteristics: tan δ = 0.19 (20°C, 120 Hz) supports repeatable AC performance in filter and decoupling networks.
• Low leakage current: 120 µA after 2 minutes at 20°C helps minimize standby losses and drift in stored-charge applications.
• RoHS compliant and production-ready: Environmentally compliant construction and mass-production availability simplify procurement and integration.
