URS2A331MHD

The URS2A331MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's URS series, designed for compact, low‑profile general‑purpose applications. It delivers 330 µF capacitance at a 100 V rating in a φ18 × 15 mm can with 7.5 mm lead spacing.

This part offers measurable performance characteristics for power-related circuitry, including defined ripple current, leakage current, and a 2000‑hour endurance rating at 85°C, making it suitable where a robust, through‑hole aluminum capacitor is required.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a 100 V rated voltage and a tolerance of −20% to +20%.
• Compact, Low‑Profile Package — φ18 × 15 mm radial can package (φ18×15L) with 7.5 mm lead spacing and 0.8 mm lead diameter, supporting space‑constrained through‑hole designs.
• Ripple Current Ratings — Low‑frequency ripple current 760 mA (120 Hz) and high‑frequency ripple current 1.14 A (10 kHz), specified to help designers manage thermal and AC stress considerations.
• Loss Tangent (tan δ) — tan δ = 0.08 measured at 20°C, 120 Hz, providing a defined dissipation characteristic for AC performance planning.
• Leakage Current — Specified leakage current 990 µA for predictable DC leakage behavior at rated conditions.
• Operating Temperature & Endurance — Rated for −40°C to +85°C with an endurance of 2000 hours at 85°C under rated voltage.
• Mounting & Packaging — Polarized radial‑lead (through‑hole) construction; available in bulk (no terminal forming) or bag packing for straightforward handling in assembly.
• Series Characteristics — Part of the URS series, characterized as compact and low‑profile for applications that require reduced board profile.

Typical Applications

• General Purpose Electronics — Suitable for a wide range of general‑purpose electronic circuits requiring a 330 µF, 100 V aluminum electrolytic capacitor.
• Through‑Hole PCB Assemblies — Radial lead configuration and bulk/bag packing support standard through‑hole assembly and handling processes.
• Space‑Constrained Designs — Compact φ18 × 15 mm can size for projects where a low profile and small footprint are required.

Unique Advantages

• High Voltage Capability: 100 V rating enables use in circuits that need higher DC voltage handling while retaining a compact through‑hole form factor.
• Defined AC Performance: Specified ripple currents at 120 Hz and 10 kHz and a measured tan δ (0.08) at 20°C/120 Hz give clear parameters for thermal and AC design considerations.
• predictable leakage: A specified leakage current of 990 µA aids designers in budgeting standby and quiescent currents in power systems.
• Robust Endurance: 2000 hours at 85°C under rated voltage provides a documented baseline for life expectancy in elevated‑temperature environments.
• Compact URS Series Design: Part of Nichicon’s compact, low‑profile URS family for consistent form‑factor selection across designs.
• Flexible Packaging: Available in bulk or bag packing to support manual insertion and common assembly workflows.
