UCS2V330MHD

The UCS2V330MHD is a radial lead aluminum electrolytic capacitor from Nichicon’s UCS series, offering 33 µF capacitance at a 350 V rating in a compact φ16 × 20 mm can. It is a general-purpose power capacitor designed for applications that require high ripple tolerance and long operating life under elevated temperatures.

Engineered for power-supply and ballast applications, the UCS2V330MHD delivers a combination of high-frequency ripple capability, extended endurance at 105°C and RoHS compliance suitable for industrial and electronic equipment designs.

Key Features

• Capacitance and Voltage — 33 µF nominal capacitance with a rated voltage of 350 V, suitable for medium-voltage smoothing and energy-storage roles.
• High Ripple Performance — Rated ripple current of 450 mA at 120 Hz (low frequency) and 900 mA at 100 kHz (high frequency), enabling use in high-ripple power circuits.
• Long Endurance — Rated for 10,000 hours at +105°C under DC bias plus rated ripple current, supporting long-term reliability in thermal stress conditions.
• Temperature Range — Operates from −40°C to +105°C, covering a wide ambient range for industrial equipment.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.24 measured at 20°C and 120 Hz, useful for designers targeting predictable ESR-related behavior.
• Leakage Current — Specified leakage current of 562 µA (consistent with the series leakage-current characterization after rated voltage application at 20°C), aiding in power-loss budgeting.
• Compact Radial Package — φ16 × 20 mm can with 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly and handling.
• Regulatory — RoHS compliant.

Typical Applications

• Power Supplies — Smoothing and energy buffering in switch-mode and linear power-supply outputs where 350 V rating and high ripple current are required.
• Ballasts — AC ballast and lamp-driver circuits that benefit from high ripple endurance and long life at elevated temperature.
• Industrial Electronics — General-purpose decoupling and bulk storage in industrial control and power modules operating up to +105°C.

Unique Advantages

• High ripple tolerance: 900 mA at 100 kHz and 450 mA at 120 Hz support demanding power-conversion environments and reduce the need for parallel components.
• Extended high-temperature life: 10,000-hour endurance at 105°C provides predictable aging and maintenance planning for long-life systems.
• Compact footprint: φ16 × 20 mm can delivers 33 µF at 350 V in a space-efficient radial package for dense board layouts.
• Predictable loss behavior: tan δ of 0.24 (20°C, 120 Hz) helps designers estimate dissipation and thermal rise tied to dielectric loss.
• Clear leakage specification: Leakage current characterized per series guidelines, enabling accurate standby-power and leakage budgeting.
• Supply readiness: Mass-production status and standard packaging options (bulk or bag) support volume procurement and assembly workflows.
