UHW1H221MPD6

The UHW1H221MPD6 is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon's UHW series. It is a radial-lead, polarized capacitor rated at 220 µF and 50 V, designed for general-purpose electronic applications that require compact size and significant ripple-handling capability.

Key value comes from a small φ10 × 12.5 mm can with low impedance and high-frequency ripple capability, combined with a wide operating temperature range and extended endurance for robust, long-life deployments.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with tolerance of −20% to +20% and rated voltage of 50 V.
• Low Impedance / High-Frequency Performance — Low impedance (150 mΩ) and a tanδ (DF) of 0.1 measured at 20°C, 120 Hz for improved high-frequency behavior.
• High Ripple Current Capability — Low-frequency ripple current of 850 mA at 120 Hz and high-frequency ripple current of 1.7 A at 10 kHz, supporting applications with significant AC content on the DC rail.
• Leakage Current — Specified leakage current of 110 µA for predictable standby losses and bias behavior.
• Temperature & Endurance — Rated for −40°C to +105°C with an endurance (life) of 10,000 hours at 105°C, suitable for extended high-temperature operation.
• Mechanical & Mounting — Compact radial can (φ10 × 12.5 mm), radial lead mounting with 5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Electronics — Suitable where a compact, polarized aluminum electrolytic capacitor is required for general circuit energy storage and biasing.
• Power Supply Filtering — Supports DC rail filtering and smoothing thanks to its 220 µF capacitance, low impedance (150 mΩ), and high ripple-current ratings.
• Embedded and Industrial Control — Designed for environments that require operation from −40°C to +105°C and extended endurance (10,000 hours at 105°C).

Unique Advantages

• Compact footprint with high performance — φ10 × 12.5 mm can delivers substantial capacitance and ripple handling in a small radial package.
• Predictable high-frequency behavior — Low impedance and specified tanδ (0.1 at 20°C, 120 Hz) support stable decoupling and filtering at higher frequencies.
• High ripple tolerance — 850 mA (120 Hz) and 1.7 A (10 kHz) ripple current ratings reduce temperature rise under AC loading and extend usable life.
• Long endurance at elevated temperature — 10,000-hour life at 105°C for designs that require sustained high-temperature reliability.
• Clear mechanical specifications — Radial lead format with defined 5 mm lead spacing and available bulk/bag packaging for straightforward PCB assembly and inventory handling.
