Key Features

• Capacitance & Voltage — 330 µF capacitance rated at 63 V to provide substantial energy storage for smoothing and decoupling in power rails.
• Low Impedance / Loss — Tangent of loss angle (tanδ) specified at 0.08 (20°C, 120 Hz) to reduce dissipation and improve efficiency under AC ripple.
• High Ripple Current Capability — Rated ripple currents of 626.4 mA at 120 Hz (low frequency) and 1.08 A at 200 kHz (high frequency) to handle switching-related ripple in power supplies.
• Long Life Endurance — Load-life endurance specified at 5000 hours at +105°C, providing stability and reliability for extended operation.
• Wide Operating Temperature — Operates from −55°C to +105°C for use in a broad range of ambient conditions.
• Radial Lead Package — φ18 × 15 mm can with 7.5 mm lead spacing (±0.5 mm) for through-hole mounting in conventional PCB layouts; available in bulk or bag packing.
• Leakage Current — Specified leakage current of 623.7 µA, measured under standard conditions.
• Regulatory — RoHS compliant for restriction of hazardous substances.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and high ripple endurance improve voltage stability and reduce heat under switching conditions.
• DC–DC Converters — Input/output smoothing and energy storage for point-of-load converters, leveraging the capacitor’s high-frequency ripple capability.
• Industrial Power Electronics — General-purpose supply decoupling and filtering in industrial control and power distribution modules operating across wide temperatures.
• Consumer & Commercial Electronics — Power rail stabilization and smoothing in devices that require reliable long-life capacitors for continuous operation.

Unique Advantages

• Low Impedance for Efficient Power Handling: The UPJ series’ low impedance character and tanδ of 0.08 reduce AC losses and help maintain stable voltages under ripple.
• High Ripple Endurance: Specified ripple current ratings at both 120 Hz and 200 kHz allow designers to address both low- and high-frequency switching environments without overspecifying parts.
• Long Operating Life at Elevated Temperature: 5000-hour endurance at 105°C increases reliability and reduces the need for frequent replacements in continuous-duty applications.
• Wide Temperature Range: −55°C to +105°C operation supports deployment in diverse ambient conditions and thermal environments.
• Through-Hole, Radial Form Factor: φ18 × 15 mm can with 7.5 mm lead spacing simplifies PCB layout for power stages and replacement designs using radial electrolytic caps.
• RoHS Compliant: Meets environmental restrictions for hazardous substances as specified in the product data.
