UPJ1H821MHD6

The UPJ1H821MHD6 is a radial-lead aluminum electrolytic capacitor designed for general-purpose power applications. It delivers 820 µF capacitance at a 50 V rating, combining low impedance characteristics with a compact radial can form factor.

Targeted use includes switching power supplies and other power-filtering roles where high ripple current capability, a wide temperature range, and long endurance are required.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance rated at 50 V for bulk energy storage and smoothing.
• Low loss (tan δ): tanδ = 0.10 measured at 20°C, 120 Hz, supporting efficient power conversion and reduced heating under AC ripple conditions.
• High ripple current handling: Rated ripple current of 1.102 A at 120 Hz and 1.53 A at 200 kHz, enabling effective suppression of switching-induced ripple.
• Long endurance: 5,000 hours load life at 105°C, providing sustained performance under elevated temperature operating conditions.
• Wide operating temperature: −55°C to +105°C for reliable operation across broad environmental conditions.
• Radial lead package: φ18 × 20 mm can with 7.5 mm lead spacing (±0.5 mm), suited for through-hole mounting and robust mechanical connection.
• Leakage current: Specified leakage current of 1,230 µA (as provided), for design-level allowance in power budgets.
• Polarized, general-purpose use: Polar capacitor construction for DC power rail applications; available in bulk or bag packing for production assembly.

Typical Applications

• Switching power supplies: Low impedance and high ripple capacity make this capacitor suitable for smoothing and output filtering in switch-mode power systems.
• General-purpose power filtering: Bulk decoupling and energy storage on DC rails in a variety of electronic equipment.
• Industrial and commercial electronics: Use in assemblies that require extended high-temperature endurance and robust radial through-hole mounting.

Unique Advantages

• Designed for high ripple environments: Specified ripple currents at both low and high frequencies allow engineers to select this part where switching noise and high-frequency ripple are present.
• Extended life at elevated temperature: 5,000-hour endurance at 105°C supports long-term reliability in thermal-stressed applications.
• Compact radial can: φ18 × 20 mm size with standard 7.5 mm lead spacing provides a space-efficient solution for through-hole boards while maintaining adequate capacitance.
• Measured loss specification: tanδ = 0.10 (20°C, 120 Hz) gives a predictable dissipation characteristic for thermal and efficiency calculations.
• RoHS compliant: Meets RoHS requirements for use in compliant manufacturing environments.
• Production-ready packaging: Available in bulk (no terminal forming) or bag packing and currently in mass production for predictable procurement.
