UCS2C220MPD

The UCS2C220MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UCS series. It is a polarized, radial-lead device specified for 22 µF at 160 V with a compact φ10 × 20 mm can and 5 mm lead spacing.

Designed for general-purpose electronics, the UCS2C220MPD is suited to applications requiring elevated-temperature endurance and elevated-frequency ripple capability, including power supply and ballast applications.

Key Features

• Capacitance and Voltage: 22 µF nominal capacitance rated at 160 V DC with capacitance tolerance of −20% to +20%.
• High ripple-current capability: Rated ripple current 250 mA at 120 Hz (low frequency) and 500 mA at 100 kHz (high frequency), enabling use under substantial AC loading.
• Long endurance at elevated temperature: Load-life specification of 8000 hours at 105°C for the φ10 × 20 mm case size.
• Low dissipation factor: tan δ (DF) 0.20 measured at 20°C, 120 Hz for the 160 V rating, supporting efficient AC performance.
• Leakage current: Specified leakage current of 240.8 µA (measured at 20°C after 1 minute of rated voltage application for this part number).
• Mechanical and mounting: Radial lead (through-hole) package, polarized, case size φ10 × 20 mm, lead spacing 5.0 mm (±0.5 mm tolerance), packaged in bulk (no terminal forming) or bag packing.
• Temperature range and compliance: Operating temperature −40°C to +105°C and RoHS compliant.

Typical Applications

• Power Supplies: Bulk/decoupling and filtering in power-supply stages where 160 V rating and high ripple capability are required.
• Ballast Circuits: Designed for ballast applications as specified for the UCS series, where elevated-temperature endurance is important.
• General Purpose Electronics: Through-hole radial-lead mounting for general-purpose boards and repairs that need a compact, high-reliability electrolytic solution.

Unique Advantages

• High ripple tolerance: 500 mA at 100 kHz and 250 mA at 120 Hz provide margin for AC stress in switching and high-frequency environments.
• Extended high-temperature life: Rated for 8000 hours at 105°C for the 10 × 20 mm case, supporting long-term operation in warm enclosures.
• Compact footprint: φ10 × 20 mm can with 5 mm lead spacing delivers a small through-hole solution where board space is limited.
• Measured low loss: tan δ = 0.20 at 20°C, 120 Hz helps maintain efficiency under AC ripple conditions.
• Predictable leakage: Specified leakage current (240.8 µA) provides verifiable selection criteria for leakage-sensitive designs.
• RoHS compliant: Conforms to RoHS requirements for environmental compliance in modern assemblies.
