UPJ1E182MHD6

The UPJ1E182MHD6 is a high-reliability, miniature aluminum electrolytic capacitor from Nichicon's UPJ series designed for low-impedance power applications. It is a radial-lead, polarized can-type capacitor specified at 1,800 µF and 25 V, with performance targets tuned for switching power supplies and general-purpose electronic equipment.

Key value comes from its combination of high ripple-current capability, extended elevated-temperature life, and a compact φ16 × 25 mm can size, supporting robust power smoothing and bulk decoupling in constrained assemblies.

Key Features

• Capacitance & Voltage — 1.8 mF (1,800 µF) rated at 25 V with a capacitance tolerance of −20% to +20% for predictable bulk energy storage.
• Low Loss / Low Impedance — tanδ (DF) = 0.14 measured at 20°C, 120 Hz; part of a low-impedance UPJ series intended for switching power supplies.
• High Ripple Current Handling — Low-frequency ripple current of 1.602 A (120 Hz) and high-frequency ripple current of 1.78 A (200 kHz), enabling effective filtering under dynamic load conditions.
• Long Endurance at Elevated Temperature — Rated life of 5,000 hours at +105°C when used under specified conditions, supporting extended field lifetimes in hot environments.
• Robust Leakage Performance — Specified leakage current of 1,350 µA following rated-voltage application conditions.
• Compact Radial Package — φ16 × 25 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for through-hole PCB installations.
• Wide Operating Temperature Range — Operates from −55°C to +105°C to cover a broad range of environmental conditions.
• Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and high ripple current handling improve voltage stability under switching loads.
• General-Purpose Power Rail Decoupling — Energy storage and transient suppression for 25 V rails in consumer and industrial electronic equipment.
• Embedded and Industrial Electronics — Durable long-life capacitor for systems requiring extended operation at elevated ambient temperatures.

Unique Advantages

• Designed for Low-Impedance Power Systems: Tangent of loss angle (tanδ) of 0.14 at 20°C/120 Hz supports lower ESR behavior beneficial to switching regulator stability.
• High Ripple Capability: Rated ripple currents up to 1.78 A (200 kHz) and 1.602 A (120 Hz) permit reliable filtering under both low- and high-frequency stress.
• Extended High-Temperature Life: 5,000 hours at +105°C gives designers predictable lifetime performance for long-running equipment.
• Compact Radial Can Footprint: φ16 × 25 mm package with 7.5 mm lead spacing enables tight PCB layouts while retaining through-hole mechanical stability.
• Predictable Leakage Characteristics: Specified leakage current of 1,350 µA for system power budgeting and startup behavior considerations.
• Regulatory Compliance: RoHS status indicated as compliant for designs requiring restricted-substance adherence.
