The UPJ1K102MHD is a high-reliability, miniature aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized can-type capacitor offering 1000 µF capacitance at an 80 V rating and is designed for general-purpose power applications.

With a wide operating temperature range of -55°C to 105°C and a rated endurance of 5000 hours at 105°C, this part targets power-filtering and switching power supply roles where low impedance, ripple handling and long life are required.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with a rated voltage of 80 V and a tolerance of -20% to +20%.
• Low Impedance / Loss — Measured tanδ (DF) of 0.08 at 20°C, 120 Hz and rated voltage, supporting efficient AC ripple attenuation.
• Ripple Current Capability — Low-frequency ripple current 1.378 A at 120 Hz and high-frequency ripple current 1.79 A at 200 kHz, enabling reliable filtering across frequency ranges.
• Long Endurance — Rated for 5000 hours at 105°C, providing sustained performance for extended duty cycles.
• Leakage Current — Specified leakage current of 2400 µA (after application of rated voltage conditions as indicated by the part data).
• Package & Mounting — Radial lead can package, size φ18 × 40 mm length, lead spacing 7.5 mm (±0.5 mm) for through-hole mounting and straightforward PCB layout.
• Environmental Compliance — RoHS compliant.
• Availability — Mass production status; packaged bulk (no terminal forming) / bag packing.

Typical Applications

• Switching Power Supplies — Low-impedance construction and high ripple-current capability make it suitable for bulk and output filtering in switching regulators.
• DC-DC Converters — Provides energy storage and smoothing for converters operating up to 80 V and across a broad temperature range.
• Industrial Power Electronics — Long endurance at elevated temperature supports continuous operation in industrial power modules and control systems.
• General Purpose Power Filtering — Polarized radial-lead format and robust electrical characteristics for decoupling and smoothing in assorted electronic equipment.

Unique Advantages

• High Voltage Handling: 80 V rating permits use in higher-voltage power stages compared with lower-voltage electrolytic options.
• Frequency Versatility: Specified ripple-current values at both 120 Hz and 200 kHz support filtering needs across low and high-frequency domains.
• Durability at Elevated Temperature: 5000-hour endurance at 105°C provides predictable lifetime performance under thermal stress.
• Compact Radial Package: φ18 × 40 mm can with 7.5 mm lead spacing simplifies through-hole assembly and mechanical retention on PCBs.
• Design Predictability: Clear electrical specs—including tanδ, leakage current, and tolerance—help with margining and reliability calculations.
• RoHS Compliant: Meets environmental directive requirements for lead-free production environments.
