UVZ1J331MPD

The UVZ1J331MPD is a radial-lead aluminum electrolytic capacitor with 330 µF capacitance and a 63 V rated voltage, designed for general-purpose applications. It offers a compact φ10 × 20 mm can size and through-hole radial mounting for straightforward integration into conventional PCB and assembly layouts.

Engineered for durability across a wide temperature span, this capacitor supports operation from −55°C to 105°C and is rated for 2000 hours at 105°C, providing stable capacitance, controlled dissipation factor, and measurable ripple handling for power decoupling and bulk energy storage tasks.

Key Features

• Electrical Capacity — 330 µF capacitance with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 63 V DC rating suitable for a range of mid-voltage power applications.
• Dissipation Factor (tan δ) — 0.1 maximum at 20°C, 120 Hz, providing a quantified loss characteristic for design calculations.
• Ripple Current Capability — Low-frequency ripple current of 510 mA at 120 Hz and high-frequency ripple current of 765 mA at 10 kHz, enabling effective smoothing and decoupling across frequency ranges.
• Leakage Current — Specified leakage current of 623.7 µA for predictable leakage behavior in bias conditions.
• Thermal and Reliability — Operates from −55°C to 105°C with an endurance rating of 2000 hours at 105°C under rated voltage.
• Package & Mounting — Radial lead can (φ10 × 20 mm) with 5.0 mm lead spacing (±0.5 mm) for through-hole assembly; available in bulk (no terminal forming) or bag packing.
• Polarized Design — Polar capacitor for correct polarity applications in DC circuits.
• RoHS Compliant — Conforms to RoHS directive per product documentation.

Typical Applications

• General-purpose circuits — Suitable where a 330 µF, 63 V radial electrolytic capacitor is specified for energy storage or decoupling.
• Through-hole power supplies — Fits conventional PCB layouts that use radial-lead components and 5.0 mm lead spacing.
• Temperature-challenged environments — Applicable in systems requiring operation between −55°C and 105°C with defined endurance at elevated temperature.

Unique Advantages

• Wide operating temperature range: −55°C to 105°C supports deployment across demanding ambient conditions.
• Verified high-temperature endurance: 2000 hours at 105°C under rated voltage provides a clear reliability baseline for design life estimates.
• Dual-frequency ripple handling: Specified ripple currents at 120 Hz and 10 kHz enable designers to account for both low- and high-frequency ripple in power circuits.
• Compact through-hole footprint: φ10 × 20 mm can with 5.0 mm lead spacing offers a space-efficient solution for legacy and industrial PCBs.
• Predictable electrical loss: tan δ = 0.1 (20°C, 120 Hz) gives a measurable parameter for loss and thermal assessment in designs.
• RoHS compliance: Meets environmental directive requirements for lead-free assemblies as documented.
