UCS2D331MHD

The UCS2D331MHD is a radial‑lead aluminum electrolytic capacitor designed for high ripple current environments and long operational life. It delivers 330 µF capacitance at a 200 V rating in a compact φ18×35.5 mm can, targeting general‑purpose power applications.

With a rated operating range of −40 °C to 105 °C and a published endurance of 10,000 hours at 105 °C, this part is suited for power supplies and ballast circuits that require durable, high‑ripple filtering components.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 200 V rated voltage for mid‑range power filtering and energy storage.
• High Ripple Current — Low‑frequency ripple current 1.61 A (120 Hz) and high‑frequency ripple current 3.22 A (100 kHz), supporting demanding AC ripple environments.
• Long Endurance — Rated life of 10,000 hours at 105 °C under DC bias plus rated ripple current, enabling extended service in thermal stress conditions.
• Temperature Range — Operates from −40 °C to 105 °C, providing a wide ambient range for industrial and commercial applications.
• Electrical Losses — Tangent of loss angle (tan δ) 0.20 measured at 20 °C, 120 Hz, indicating controlled dissipation characteristics.
• Leakage Current — Measured leakage current of 2740 µA (after 1 minute at 20 °C), useful for budgeting standby losses.
• Form Factor & Mounting — Radial lead can, size φ18×35.5 mm, lead spacing 7.5 mm (±0.5 mm) for through‑hole assembly and straightforward PCB layout.
• Compliance & Availability — RoHS compliant and listed as mass production with bulk or bag packing options for production quantities.

Typical Applications

• Power Supplies — Bulk filtering and output smoothing in switch‑mode and linear power supplies where high ripple current capability is required.
• Ballast Circuits — Energy storage and ripple handling for ballast and lamp‑drive circuits specified in the series notes.
• General‑Purpose Electronics — Through‑hole designs needing a reliable, long‑life electrolytic solution for decoupling and energy buffering.

Unique Advantages

• High ripple endurance: Rated ripple currents of 1.61 A (120 Hz) and 3.22 A (100 kHz) reduce overheating risk and extend capacitor service life in high‑stress power circuits.
• Long operational life: 10,000‑hour endurance at 105 °C provides predictable lifetime performance for designs requiring extended maintenance intervals.
• Wide temperature capability: −40 °C to 105 °C operation supports deployment across a broad range of environmental conditions.
• Compact radial package: φ18×35.5 mm can with 7.5 mm lead spacing simplifies through‑hole PCB integration while preserving usable capacitance and ripple handling.
• Production readiness: Mass production status and packaging options (bulk or bag) facilitate procurement for volume builds.
• RoHS compliant: Conforms to RoHS directives to meet regulatory and environmental requirements.
