UPJ1J181MHD6

The UPJ1J181MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized can designed for general-purpose power filtering with performance characteristics aimed at switching power supplies and other power-conversion applications.

Key value comes from a compact φ16 × 15 mm can, a rated voltage of 63 V at 180 µF, long operational life at elevated temperature, and ripple-handling capability across low and high frequencies.

Key Features

• Electrical Rating — 180 µF capacitance at a rated voltage of 63 V with capacitance tolerance ±20% (measured at 120 Hz, 20°C).
• Low Loss Characteristic — tanδ (DF) 0.08 measured at 20°C, 120 Hz, supporting stable performance in AC ripple conditions.
• Ripple Current Capability — Low-frequency ripple current 405 mA at 120 Hz and high-frequency ripple current 750 mA at 200 kHz, enabling effective smoothing for switching supplies.
• Leakage Current — Specified leakage current of 340.2 µA after application of rated voltage, suitable for typical power-filtering requirements.
• High Reliability / Long Life — Endurance rated for 5000 hours at 105°C under rated DC bias plus rated ripple current.
• Wide Operating Temperature — Specified for −55°C to +105°C to cover demanding thermal environments.
• Compact Radial Package — Radial lead, can package with a φ16 × 15 mm body and 7.5 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk/bag packing.
• RoHS Compliant — Meets RoHS requirements as indicated in the product data.

Typical Applications

• Switching Power Supplies — Filter and stabilize output rails; UPJ series is specified as ideally suited for switching power supply use.
• DC Power Filtering — Bulk and smoothing capacitor for DC-DC converters and linear regulators where compact size and ripple handling are required.
• Industrial Power Electronics — General-purpose decoupling and energy storage in industrial control and power modules operating across −55°C to +105°C.

Unique Advantages

• Balanced Ripple Performance: Dual ripple ratings (405 mA at 120 Hz and 750 mA at 200 kHz) provide measurable capability across low and high-frequency conditions.
• Extended High-Temperature Life: 5000-hour endurance at 105°C reduces frequency of capacitor replacement in elevated-temperature installations.
• Compact Footprint: φ16 × 15 mm can with 7.5 mm lead spacing delivers high capacitance in a small radial package for space-constrained designs.
• Controlled Losses: tanδ of 0.08 (20°C, 120 Hz) helps maintain efficiency and predictable thermal behavior under AC ripple.
• Breadth of Use: Polarized aluminum electrolytic construction and general-purpose rating make it suitable for a wide range of power-filtering roles.
• Regulatory Compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
