UCA2C221MHD

The UCA2C221MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UCA series, designed for miniature-package applications that require high ripple current capability and extended operational life. It is specified at 220 µF and 160 V with a tolerance of ±20% and a compact case of φ16 × 30.5 mm (lead spacing 7.5 mm).

Engineered for power-supply and ballast use as well as general-purpose electronic assemblies, this capacitor combines high-frequency ripple handling (1.4 A at 100 kHz) with long life (12,000 hours at 105°C) and RoHS compliance to support robust designs operating between −25°C and +105°C.

Key Features

• Capacitance & Rated Voltage — 220 µF at 160 V with ±20% tolerance, suitable for energy storage and smoothing tasks within its rated voltage.
• High Ripple Current Capability — Rated ripple current of 1.4 A at 100 kHz and 700 mA at 120 Hz, specified for sustained AC ripple conditions.
• Long Life at Elevated Temperature — Load-life rating of 12,000 hours at 105°C, supporting extended operation in high-temperature environments.
• Compact Radial Can Package — φ16 × 30.5 mm case with 7.5 mm lead spacing (radial lead), enabling straightforward through-hole mounting and PCB placement.
• Wide Operating Temperature Range — Specified for −25°C to +105°C to accommodate a range of ambient conditions.
• Leakage Current — Specified leakage current of 1508 µA (as provided in product data).
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power Supplies — Filtering and smoothing in switching and linear power supplies where elevated ripple currents are present.
• Ballasts — Suitable for ballast applications referenced in the product documentation, benefitting from the capacitor’s ripple and life specifications.
• General-Purpose Electronics — Through-hole radial mounting for a variety of industrial and consumer electronic circuits requiring durable electrolytic capacitance.

Unique Advantages

• High-frequency ripple capability: 1.4 A rating at 100 kHz helps the capacitor accommodate demanding AC ripple loads typical in switching environments.
• Extended high-temperature life: 12,000 hours at 105°C provides a clear, quantifiable endurance metric for thermal-stressed designs.
• Compact radial form factor: φ16 × 30.5 mm can and 7.5 mm lead spacing offer a space-efficient option for through-hole assemblies.
• Wide ambient range: −25°C to +105°C operating range supports deployment across varied environmental conditions.
• Regulatory compliance: RoHS status supports designs targeting regulated markets.
