UCS2C331MHD

The UCS2C331MHD is a miniature, radial‑lead aluminum electrolytic capacitor designed for high ripple current and extended operational life. As a polarized radial can capacitor, it is intended for general-purpose power applications where elevated temperature endurance and sustained ripple handling are required.

Key value propositions include a 330 µF capacitance at 160 V rated voltage, rated operation from −40 °C to +105 °C, and long life under load—making it suitable for power supplies and ballast applications that demand reliability in compact through‑hole designs.

Key Features

• Electrical Performance — 330 µF nominal capacitance with ±20% tolerance and 160 V rated voltage, suited for bulk filtering and energy storage in power circuits.
• High Ripple Current — Specified ripple current of 1.565 A at 120 Hz and 3.13 A at 100 kHz, supporting demanding AC‑ripple conditions in power supplies and ballast circuits.
• Long Life & Endurance — Load life specified up to 10,000 hours at +105 °C (series load life range 8,000–10,000 hours depending on case size), enabling extended service in high‑temperature environments.
• Temperature Range — Rated for operation from −40 °C to +105 °C for stable performance across a wide ambient range.
• Leakage and Loss Characteristics — Leakage current limits follow the series specification (≤ 0.04CV + 100 µA after 1 minute at 20 °C) and tan δ max of 0.20 at the 160 V rating, offering predictable loss and self‑heating behavior.
• Compact Radial Can Package — Radial lead mounting with 7.5 mm lead spacing and compact dimensions (L: 3.05 × D: 1.8 cm), facilitating dense through‑hole layouts.
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), suitable for designs needing lead‑free material compliance.

Typical Applications

• Power Supplies — Bulk filtering and smoothing where high ripple current capability and 160 V rating are required to maintain stable output under load.
• Ballast Circuits — Supports lighting ballast applications that demand sustained ripple handling and long operational life at elevated temperatures.
• General Purpose Through‑Hole Designs — Compact radial can construction and standard lead spacing make the part suitable for a wide range of PCB power modules and retrofit applications.

Unique Advantages

• High Ripple Handling: Specified ripple currents at both low and high frequencies (1.565 A at 120 Hz, 3.13 A at 100 kHz) reduce the need for parallel components in many designs.
• Extended High‑Temperature Life: Up to 10,000 hours at +105 °C provides predictable longevity in hot operating environments, lowering maintenance and replacement frequency.
• Compact Footprint: Small radial can dimensions (3.05 × 1.8 cm) and 7.5 mm lead spacing enable space‑constrained PCB layouts without sacrificing capacity.
• Predictable Leakage and Loss: Leakage current and tan δ specifications allow accurate thermal and discharge planning in power designs.
• RoHS Compliance: Material compliance simplifies regulatory acceptance for commercial and industrial equipment.
• Trusted Manufacturer: Part of Nichicon’s UCS series, providing consistency with a documented series specification for designers referencing endurance and electrical characteristics.
