URS1J331MHD

The URS1J331MHD is a radial‑lead aluminum electrolytic capacitor from Nichicon's URS series, offering 330 µF capacitance at a 63 V rating in a compact, low‑profile can (φ12.5 × 15L). It is designed as a general‑purpose polarized capacitor for through‑hole applications requiring bulk capacitance in a small footprint.

Key value is provided through its combination of rated voltage, measurable ripple current capability at both low and high frequencies, defined loss tangent, and a 2000‑hour endurance specification at 85°C—delivering predictable behavior for power filtering and energy storage roles in many electronic designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 63 V and tolerance of −20% to +20% for reliable bulk energy storage.
• Low‑loss Characteristics — tanδ (loss tangent) specified at 0.10 measured at 20°C and 120 Hz, enabling predictable impedance and loss performance in AC and ripple environments.
• Ripple Current Capability — Low‑frequency ripple current of 710 mA at 120 Hz and high‑frequency ripple current of 1.065 A at 10 kHz, suitable for smoothing and decoupling where AC ripple is present.
• Leakage Current — Specified leakage current of 623.7 µA to help set standby and bias current expectations in your design.
• Temperature & Endurance — Rated operating temperature −40°C to +85°C with an endurance of 2000 hours at 85°C under rated voltage, providing defined lifetime behavior under elevated temperature stress.
• Compact Radial Package — Radial, can‑style package with dimensions φ12.5 × 15 mm and 5.0 mm lead spacing (±0.5 mm), for straightforward through‑hole mounting and layout planning.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing and listed as mass production, simplifying procurement and handling for production volumes.

Typical Applications

• Power supply smoothing — Bulk capacitance and defined ripple ratings make the URS1J331MHD suitable for smoothing and filtering in linear and switching power supplies.
• Output decoupling for converters — 330 µF at 63 V with high‑frequency ripple current capability supports output filtering on DC–DC converter stages.
• Industrial control electronics — Rated for −40°C to +85°C and 2000 h endurance at 85°C, useful where long‑term thermal stability and predictable lifetime are required.
• General‑purpose energy storage — Polarized, radial‑lead format provides compact bulk energy storage for a variety of general‑purpose electronic circuits.

Unique Advantages

• Clear electrical specification set — Explicit values for capacitance, voltage, tanδ, leakage, and ripple currents allow precise engineering tradeoffs during design.
• Measurable ripple performance at multiple frequencies — Separate low‑frequency (120 Hz) and high‑frequency (10 kHz) ripple current ratings enable designers to size capacitors against real ripple conditions.
• Compact, low‑profile footprint — φ12.5 × 15 mm can with 5.0 mm lead spacing fits space‑constrained through‑hole layouts while delivering substantial capacitance.
• Defined high‑temperature endurance — 2000 hours at 85°C under rated voltage provides a clear reliability baseline for thermal stress planning.
• Production‑ready packaging — Offered in bulk or bag packing and available in mass production for streamlined sourcing and assembly.
