UHW1H221MPD

The UHW1H221MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial lead, polarized component specified at 220 µF and 50 V, designed for general-purpose electronic circuits that require sustained ripple handling and extended endurance.

Key value comes from its combination of high ripple-current capability, low impedance at higher frequencies, and long operating life (10,000 hours at 105°C), making it suitable for designs that demand reliable bulk capacitance in a compact can-style package.

Key Features

• Electrical Rating: 220 µF capacitance at a rated voltage of 50 V with tolerance ±20% (measured at 120 Hz, 20°C).
• Low Loss (tan δ): tanδ of 0.10 at 20°C, 120 Hz, supporting stable performance in AC-biased applications.
• Low Impedance: Rated impedance of 126 mΩ helps reduce voltage ripple at higher frequencies.
• High Ripple Current: Low-frequency ripple current 825 mA (120 Hz) and high-frequency ripple current 1.65 A (10 kHz), with frequency coefficients defined by the UHW series.
• Leakage Current: Specified leakage current of 110 µA after application of rated voltage.
• Long Endurance: Rated for 10,000 hours at 105°C under the UHW series endurance definition.
• Operating Temperature Range: –40°C to +105°C to cover a wide range of ambient conditions.
• Compact Radial Package: Can-style radial package φ10 × 16L with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• RoHS Compliant: Constructed in accordance with RoHS requirements.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple handling for general-purpose circuits that require a 220 µF, 50 V polarized radial capacitor.
• Decoupling and smoothing in power modules — Compact radial can offers a reliable option where low impedance and high ripple current are needed in a small footprint.
• Industrial and embedded electronics — Rated for –40°C to 105°C and 10,000 h endurance at 105°C, suitable for long-life installations in constrained enclosures.

Unique Advantages

• High ripple capability: 1.65 A at 10 kHz and 825 mA at 120 Hz provide headroom for AC ripple and switching noise mitigation.
• Compact, space-saving form factor: φ10 × 16L can with 5 mm lead spacing delivers 220 µF capacitance while minimizing board area.
• Extended high-temperature life: 10,000 hours at 105°C reduces the need for frequent replacements in high-temperature environments.
• Low impedance and low loss: 126 mΩ impedance and tanδ 0.10 at 120 Hz help maintain voltage stability and reduce heat generation under AC stress.
• Polarized radial lead convenience: Standard radial lead configuration simplifies through-hole assembly and prototyping workflows.
• Regulatory compliance: RoHS compliance supports regulatory and environmental requirements.
