UHW0J221MDD

The UHW0J221MDD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It combines a compact φ5×11 mm case and 2 mm lead spacing with performance characteristics targeted at power filtering and ripple handling in space-constrained assemblies.

Key value propositions include robust ripple-current capability across low and high frequencies, a broad operating temperature range from −40°C to 105°C, and a demonstrated endurance of 6000 hours at 105°C—delivering dependable operation where elevated temperature life and compact size matter.

Key Features

• Capacitance and Voltage: 220 µF nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20%.
• High-frequency performance: Lower impedance at high frequency and a specified high-frequency ripple current of 450 mA at 10 kHz, supporting high-frequency smoothing tasks.
• Low-frequency ripple handling: 225 mA ripple current at 120 Hz for bulk filtering and supply decoupling.
• Reliability and endurance: Rated for 6000 hours at 105°C under specified test conditions, designed as a high-reliability type within the UHW series.
• Electrical losses and leakage: tanδ (DF) of 0.21 measured at 20°C, 120 Hz; specified leakage current of 13.86 µA.
• Mechanical package: Radial lead can, size φ5 × 11 mm (L: 1.1 × D: 0.5 cm), lead spacing 2 mm with 0.5 mm tolerance; offered as Bulk (no terminal forming) / Bag packing.
• Operating range and compliance: Operating temperature −40°C to 105°C and RoHS compliant.
• Availability status: End Of Life.

Typical Applications

• General-purpose power filtering: Bulk and decoupling capacitor for compact power supplies, leveraging 220 µF capacitance and 225 mA ripple current at 120 Hz.
• High-frequency smoothing: Applications requiring lower impedance at high frequency and 450 mA ripple capability at 10 kHz.
• Space-constrained through-hole designs: Small φ5×11 mm can and 2 mm lead spacing make this capacitor suitable where board area is limited but through-hole mounting is required.

Unique Advantages

• Compact footprint with strong ripple capability: φ5×11 mm size combines small board area with 225 mA (120 Hz) and 450 mA (10 kHz) ripple ratings.
• Designed for elevated-temperature endurance: 6000-hour rating at 105°C provides quantifiable life performance for long-run operation in warm environments.
• Low loss and controlled leakage: tanδ of 0.21 (20°C, 120 Hz) and leakage current of 13.86 µA support stable behavior in power circuits.
• Through-hole radial format: Standard radial lead and 2 mm spacing simplify assembly for legacy or mixed-technology boards.
• Regulatory compliance: RoHS-compliant construction supports restricted-substance requirements in many global markets.
