UHD1H221MPD

The UHD1H221MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UHD series. It is a polarized, radial-lead can designed for general-purpose electronic applications that require compact energy storage with low impedance and high ripple-handling capability.

Engineered for continuous operation across −40°C to 105°C and rated for 4,000 hours at 105°C, this 220 µF, 50 V capacitor delivers measurable performance for designs that demand sustained ripple current tolerance and stable electrical characteristics over time.

Key Features

• Electrical Specification — 220 µF capacitance with a rated voltage of 50 V and capacitance tolerance of −20% to +20%.
• Low Loss / Low tan δ — tanδ of 0.10 (measured at 20°C, 120 Hz) to minimize dissipation in AC/ripple environments.
• High Ripple Current Capability — Low-frequency ripple current of 959 mA at 120 Hz and high-frequency ripple current of 1.37 A at 100 kHz, supporting heavy ripple workloads.
• Temperature and Endurance — Operating range of −40°C to 105°C with an endurance rating of 4,000 hours at 105°C.
• Compact Radial Package — φ10 × 16 mm can with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through-hole implementations.
• Leakage Current — Specified leakage current of 110 µA (after 2 minutes, at 20°C) for predictable quiescent behavior.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.
• High-frequency performance — Designed for lower impedance at high frequencies; frequency coefficient behavior for 100–330 µF applies (e.g., coefficient = 1.00 at 100 kHz).

Typical Applications

• General-purpose electronic circuits — Polarized energy storage where a 220 µF, 50 V capacitor with low impedance and predictable leakage is required.
• High-ripple DC circuits — Circuits that require sustained ripple handling up to 959 mA (120 Hz) and 1.37 A (100 kHz) benefit from the UHD1H221MPD’s ripple ratings.
• Industrial control and power modules — Use where wide operating temperature (−40°C to 105°C) and long endurance (4,000 hours at 105°C) are necessary.

Unique Advantages

• Measurable ripple performance: Specified ripple current values at both low and high frequencies allow designers to size capacitors based on empirical ripple requirements.
• Low dissipation in AC conditions: A tanδ of 0.10 at 120 Hz (20°C) reduces heat generation and helps maintain stability under ripple stress.
• Compact, through-hole form factor: φ10 × 16 mm radial can and standardized 5.0 mm lead spacing simplify PCB layout for through-hole assemblies.
• Extended high-temperature endurance: Rated for 4,000 hours at 105°C to support designs that require long-term stability at elevated temperatures.
• Predictable leakage: Leakage current specified at 110 µA (20°C, after 2 minutes) enables tighter control of standby and quiescent current budgets.
• RoHS compliance: Meets RoHS requirements for easier regulatory integration into commercial and industrial products.

Why Choose UHD1H221MPD?

The UHD1H221MPD combines compact radial-can packaging with data-driven electrical performance—220 µF at 50 V, low tanδ, and defined ripple-current ratings—making it a practical choice where reliable AC/ripple handling and long-term high-temperature endurance are important. Its specified leakage and tolerance figures support predictable behavior in power-holding and smoothing applications.

This capacitor is well suited to engineers and procurement teams designing general-purpose and industrial electronics that require a robust through-hole aluminum electrolytic with clear, verifiable specifications and RoHS compliance from Nichicon’s UHD series.
