UPJ1V821MHD

The UPJ1V821MHD is an aluminum electrolytic capacitor from Nichicon's UPJ series designed for low impedance performance in switching power environments. It is a polarized, radial-lead can with 820 µF capacitance at a 35 V rating and a broad operating temperature range of -55 °C to 105 °C.

Targeted for general-purpose power filtering and energy storage, this part delivers high ripple-current capability and a long rated life of 5000 hours at 105 °C, making it suitable for power-supply filtering and other DC rail applications where durability and ripple handling matter.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20 °C for predictable bulk energy storage.
• Low Impedance Design: UPJ series specification targeted for switching power supplies—optimized to reduce impedance in power-filtering applications.
• Ripple Current Handling: Rated low-frequency ripple current of 1.0728 A at 120 Hz and high-frequency ripple current of 1.49 A at 200 kHz to support both mains-frequency and switching-frequency ripple rejection.
• Loss Characteristics: Tangent of loss angle (tan δ) 0.12 (measured at 20 °C, 120 Hz), supporting stable dissipation performance under rated conditions.
• Leakage Current: Specified leakage current of 861 µA after voltage application, enabling predictable quiescent loss budgeting.
• Thermal Endurance: Rated life of 5000 hours at 105 °C, providing long-term reliability under elevated operating temperature.
• Form Factor & Mounting: Radial-lead can, size φ12.5 × 25 mm, lead spacing 5.0 mm (±0.5 mm), suited for through-hole board mounting.
• Compliance & Availability: RoHS compliant and currently in mass production; available packaging includes bulk (no terminal forming) and bag packing.

Typical Applications

• Switching Power Supplies: Bulk filtering and output smoothing where low impedance and high ripple current capacity improve voltage regulation and reduce noise.
• DC-DC Converters: Input and output decoupling to handle switching transients and maintain stable DC rails in converter designs.
• Industrial Power Electronics: Energy storage and smoothing on power rails in industrial control equipment operating across a wide temperature range.
• General-Purpose Power Filtering: Board-level decoupling and reservoir capacitors for consumer or commercial electronics requiring durable, polarized capacitance.

Unique Advantages

• Robust Ripple Performance: Dual ripple-current ratings for 120 Hz and 200 kHz give designers data to size capacitors for both line-frequency and switching-frequency stresses.
• Long High-Temperature Life: 5000-hour endurance at 105 °C supports designs that must maintain capacitance and leakage characteristics over extended elevated-temperature operation.
• Predictable Loss and Leakage: Specified tan δ and leakage current values (0.12 and 861 µA respectively) simplify thermal and power-loss calculations.
• Compact Through-Hole Package: φ12.5 × 25 mm radial can with 5 mm lead spacing balances capacitance density and board-level ease of assembly.
• Regulatory Compliance: RoHS-compliant construction for use in regulated markets and product lines.
• Production Ready: Mass-production status and standard packaging options support volume procurement and manufacturing planning.
