UHE1H221MPD

The UHE1H221MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UHE series. It is a polarized, radial-lead can designed for general-purpose electronic use where long life and low impedance are required.

Key attributes include a 220 µF capacitance at 50 V, compact φ10 × 16 mm can size with 5 mm lead spacing, and long endurance specified at 7000 hours at 105°C—making it suitable for a wide range of general-purpose electronic circuits.

Key Features

• Electrical Performance 220 µF nominal capacitance with tolerance of −20% to +20% and a rated voltage of 50 V. Specified impedance is 340 mΩ and tangent of loss angle (tanδ) is 0.10 at 20°C, 120 Hz.
• Ripple Current Capability Low-frequency ripple current 735 mA at 120 Hz and high-frequency ripple current 1.05 A at 10 kHz, supporting AC ripple handling across common frequency ranges.
• Leakage Current Specified leakage current of 110 µA after application of rated voltage, enabling predictable steady-state leakage behavior.
• Reliability & Endurance High-reliability UHE series design with rated endurance of 7000 hours at 105°C under rated bias and ripple conditions.
• Mechanical & Mounting Radial lead (polar) package in a φ10 × 16 mm aluminum can with 5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing.
• Operating Range Temperature range from −40°C to +105°C for broad environmental compatibility within the specified operating window.
• RoHS Compliance Product is RoHS compliant as stated in the product data.

Typical Applications

• General-purpose electronic circuits — Intended for general-purpose use in electronic equipment that requires a 220 µF, 50 V polarized aluminum electrolytic capacitor.
• Power filtering and decoupling — Used where designers require defined ripple current handling and low impedance at typical power frequencies.
• Industrial and commercial equipment — Suitable for electronic products and modules that need long endurance at elevated temperatures within the specified operating range.

Unique Advantages

• Long high-temperature endurance: 7000 hours of rated life at 105°C provides predictable long-term performance in elevated-temperature environments.
• High ripple capability: 735 mA (120 Hz) and 1.05 A (10 kHz) ripple ratings support both low- and high-frequency ripple stresses.
• Low dissipation factor and impedance: tanδ of 0.10 (20°C, 120 Hz) and 340 mΩ impedance help reduce losses and improve voltage stability under load.
• Compact radial package: φ10 × 16 mm can with 5 mm lead spacing offers a small footprint for through-hole assemblies while preserving capacitance and voltage rating.
• Predictable leakage behavior: Specified leakage current of 110 µA assists in power budgeting and standby loss calculations.
• RoHS compliant: Meets RoHS requirements for material compliance in many regional markets.
