UCS2C330MPD

The UCS2C330MPD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCS series. It is a radial-lead, polarized can-style capacitor specified at 33 µF and 160 V, designed for general-purpose power applications requiring elevated temperature endurance and high ripple handling.

Targeted use cases include power supplies and ballast circuits where compact size, long operating life at high temperature, and reliable ripple performance are required.

Key Features

• Electrical characteristics — 33 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 160 V.
• Low loss — Tangent of loss angle (tan δ) specified at 0.20 (measured at 20°C, 120 Hz) to help minimize dissipation in filtering and smoothing applications.
• High ripple capability — Rated ripple currents of 325 mA at 120 Hz (low frequency) and 650 mA at 100 kHz (high frequency) to support demanding power-conditioning tasks.
• Long life at elevated temperature — Endurance rated for 8000 hours at 105°C, meeting the UCS series long-life specification for sustained high-temperature operation.
• Compact radial package — ϕ10 × 20 mm can with radial leads, 5.0 mm lead spacing (±0.5 mm), suitable for through-hole mounting and conservative PCB footprinting.
• Leakage current — Specified leakage current of 311.2 µA (measured after 1 minute at 20°C), consistent with established UCS series limits.
• Compliance & availability — RoHS compliant and offered in bulk or bag packing; currently in mass production.

Typical Applications

• Power supplies — Bulk filtering and output smoothing in medium-voltage DC rails where 160 V rating and high ripple tolerance are required.
• Ballast circuits — Energy storage and ripple handling in ballast and lamp-driver topologies that operate at elevated temperatures.
• General-purpose high-voltage decoupling — Compact through-hole solution for decoupling, filtering, and energy buffering in industrial and commercial electronics.

Unique Advantages

• Compact high-voltage solution: 160 V rating in a ϕ10 × 20 mm can provides a small footprint for designs constrained by board area.
• Designed for sustained high-temperature operation: 8000-hour endurance at 105°C supports reliability in thermally demanding environments.
• Robust ripple handling: Specified ripple currents at both low and high frequency (325 mA at 120 Hz, 650 mA at 100 kHz) accommodate a range of power-conditioning needs.
• Predictable dissipation: Tan δ = 0.20 at 20°C/120 Hz yields a defined loss characteristic useful for thermal and efficiency calculations.
• Through-hole mounting convenience: Radial leads with 5.0 mm spacing and 0.5 mm tolerance simplify assembly and rework for legacy and industrial PCBs.
• Regulatory compliance and supply: RoHS compliant and in mass production, facilitating regulatory alignment and procurement.
