UPJ1E821MHD6

The UPJ1E821MHD6 is an aluminum electrolytic capacitor in a radial lead can intended for power filtering and smoothing applications. It provides 820 µF capacitance at a 25 V rating with a polarized radial-lead package and compact φ16 × 15 mm dimensions.

Designed as a low-impedance, long-life part for switching power supplies and general-purpose power rails, this Nichicon UPJ-series capacitor offers high ripple-current capability, a wide operating temperature range, and 5000 hours endurance at 105°C for reliable performance in demanding power designs.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a 25 V rated voltage with ±20% tolerance (120 Hz, 20°C).
• Low Impedance — UPJ series specification states low impedance optimized for switching power supplies, improving ripple suppression and stability on power rails.
• High Ripple Current Handling — Low-frequency ripple current of 813.6 mA at 120 Hz and high-frequency ripple current of 1.13 A at 200 kHz support heavy AC stress on DC rails.
• Long Life at Elevated Temperature — Rated for 5000 hours of endurance at 105°C, supporting prolonged operation under thermal load.
• Thermal and Loss Characteristics — tanδ of 0.14 (measured at 20°C, 120 Hz) and operating temperature range from −55°C to +105°C.
• Radial Lead Package — φ16 × 15 mm can size with 7.5 mm lead spacing (±0.5 mm), delivered in bulk or bag packing for flexible procurement and assembly.
• Leakage Current — Specified leakage current of 615 µA (after application of rated voltage conditions appropriate to the part).
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where low impedance and high ripple capability improve regulation and reduce output ripple.
• DC-DC Converters — Input and output decoupling for converters that require stable capacitance under high-frequency ripple conditions.
• Industrial Power Electronics — General-purpose power-rail filtering in industrial control and instrumentation systems operating across a wide temperature range.
• Consumer Power Modules — Power filtering and energy storage in compact assemblies where a radial lead can and defined lead spacing are required.

Unique Advantages

• Low-impedance design for improved ripple suppression: The UPJ-series low-impedance construction combined with measured ripple-current ratings helps reduce voltage ripple on power rails.
• High-temperature endurance: 5000-hour rated life at 105°C supports long-term reliability under sustained thermal stress.
• Verified AC stress capability: Separate low-frequency (120 Hz) and high-frequency (200 kHz) ripple-current specifications provide clear guidance for application in both mains-related and switching environments.
• Compact radial form factor: φ16 × 15 mm can with 7.5 mm lead spacing simplifies layout and mechanical retention in through-hole assemblies.
• RoHS compliance and mass-production availability: Environmentally compliant manufacturing and mass-production status help with consistent supply and regulatory requirements.
