UCY2W120MPD

The UCY2W120MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series designed for high-voltage, high-ripple applications. It provides 12 µF capacitance at a 450 V rating in a compact φ10 × 20 mm can with 5 mm lead spacing.

Engineered for long-life operation and high ripple tolerance, this part is intended for power supplies, ballast circuitry and automotive electronics where a combination of voltage capability, endurance and compact packaging is required. It is RoHS compliant and AEC-Q200 qualified.

Key Features

• Capacitance & Voltage — 12 µF rated capacitance at 450 V, suitable for high-voltage smoothing and energy-storage roles.
• High ripple current capability — Low-frequency ripple current 150 mA at 120 Hz and high-frequency ripple current 300 mA at 100 kHz, improving performance in switching and noisy environments.
• Long endurance — Rated for 10,000 hours at 105°C, offering stability for extended high-temperature operation.
• Low leakage and controlled dissipation — Specified leakage current of 316 µA and tan δ (DF) 0.24 measured at 20°C, 120 Hz.
• Compact radial can package — φ10 × 20 mm body with 5 mm lead spacing (lead spacing tolerance ±0.5 mm), available in bulk or bag packing.
• Wide operating temperature — Rated for −40°C to +105°C to support demanding thermal environments.
• Automotive-capable — AEC-Q200 qualification for designs requiring automotive-level reliability.
• RoHS compliant — Meets RoHS requirements for regulatory compliance.

Typical Applications

• Automotive power electronics — High-voltage smoothing and decoupling in automotive inverters, converters, and auxiliary power modules where AEC-Q200 qualification and long life are required.
• Switch-mode power supplies — Bulk and output filtering for high-voltage SMPS designs benefitting from high ripple-current capability and low leakage.
• Lighting ballasts — Energy storage and noise suppression in ballast and lamp driver circuits where high-voltage endurance is needed.
• Industrial power control — Filtering and transient absorption in compact high-voltage industrial controllers and power assemblies.

Unique Advantages

• High-voltage capability: 450 V rating enables use in higher-voltage rails without increasing component count.
• High ripple endurance: 150 mA (120 Hz) and 300 mA (100 kHz) ripple ratings reduce stress on surrounding circuitry in high-switching environments.
• Designed for extended high-temperature operation: 10,000-hour life at 105°C supports long-term reliability in thermal-stressed applications.
• Compact radial form factor: φ10 × 20 mm can and 5 mm lead spacing offer a small footprint for space-constrained boards.
• Measured performance parameters: Specified tan δ (0.24 at 20°C, 120 Hz) and defined leakage current (316 µA) give predictable electrical behavior for design validation.
• Automotive-grade qualification: AEC-Q200 status supports integration into automotive electronic systems.
