UPJ1K101MHD6

The UPJ1K101MHD6 is a radial lead, polarized aluminum electrolytic capacitor from Nichicon’s UPJ series, offering a 100 µF capacitance at an 80 V rating. It delivers low impedance and high reliability for power-electronics use, with a compact φ12.5 × 15 mm can and 5 mm lead spacing.

Designed for general-purpose power applications and explicitly suited for switching power supplies, this part combines a wide operating temperature range (−55°C to 105°C) with a long endurance rating to meet sustained load conditions.

Key Features

• Electrical Rating — 100 µF capacitance at 80 V DC with a ±20% tolerance, providing a defined energy-storage element for power circuits.
• Low Impedance Performance — UPJ series low-impedance construction with a measured tanδ of 0.08 (20°C, 120 Hz), supporting efficient AC ripple handling in power stages.
• Ripple Current Capability — Specified low-frequency ripple current of 160.16 mA (120 Hz) and high-frequency ripple current of 308 mA (200 kHz), enabling performance across switching and line-frequency domains.
• Leakage Current — Leakage current rated at 240 µA, for predictable DC characteristics after voltage application.
• Reliability & Endurance — Load-life endurance specified at 5000 hours at 105°C, supporting long-term operation under elevated-temperature stress.
• Wide Operating Temperature — Rated for −55°C to +105°C to cover common industrial and embedded environments.
• Radial Mechanical Package — φ12.5 × 15 mm can with 5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assemblies.
• RoHS Compliant — Meets RoHS directive requirements as stated for the UPJ series.

Typical Applications

• Switching Power Supplies — Input/output smoothing and energy buffering where low impedance and reliable ripple handling are required.
• General-Purpose Power Circuits — Bulk decoupling and DC filtering in industrial and embedded power designs.
• Power-Conversion Modules — Use in converter intermediate stages where endurance at elevated temperature is important.

Unique Advantages

• High Voltage Margin: 80 V rating enables use in higher-voltage rails without upsizing capacitance value.
• Long Endurance at Elevated Temperature: 5000-hour rated life at 105°C supports designs expected to run under sustained thermal stress.
• Dual-Frequency Ripple Handling: Specified ripple currents at both 120 Hz and 200 kHz provide measurable performance for line-frequency and switching-frequency scenarios.
• Compact Radial Form Factor: φ12.5 × 15 mm can with standard 5 mm lead spacing simplifies through-hole layout and mechanical retention.
• Predictable Leakage and Loss: Leakage current of 240 µA and tanδ of 0.08 (20°C, 120 Hz) allow accurate bias and thermal planning in power designs.
• RoHS Compliance: Conforms to RoHS directives for regulatory alignment in many commercial and industrial products.
