UPJ1V182MHD6

The UPJ1V182MHD6 is a radial-lead aluminum electrolytic capacitor in Nichicon's UPJ series designed for low impedance, general-purpose power applications. With 1.8 mF capacitance at 35 V and a compact φ18 × 25 mm can, it is well suited for switching power supplies and power-smoothing duties where high ripple handling and long life at elevated temperatures are required.

This part combines high ripple-current capability, a wide operating temperature range of -55 °C to +105 °C, and a rated load life of 5000 hours at 105 °C to deliver reliability in demanding power designs.

Key Features

• Capacitance & Voltage — 1.8 mF (1800 µF) rated at 35 V for bulk energy storage and decoupling in power rails.
• Low Impedance Design — UPJ series low-impedance construction specified for switching power supplies, improving transient response and ripple attenuation.
• High Ripple Current Handling — Rated low-frequency ripple current 1.854 A at 120 Hz and high-frequency ripple current 2.06 A at 200 kHz to support high-switching-rate converters.
• Loss Characteristics — tan δ = 0.12 measured at 20 °C, 120 Hz, suitable for predictable AC loss behavior in power applications.
• Reliability & Lifetime — Rated for 5000 h at 105 °C under specified load conditions to support long-term operation in elevated-temperature environments.
• Mechanical & Mounting — Radial-lead can (φ18 × 25 mm) with 7.5 mm lead spacing (±0.5 mm) for through-hole assembly and straightforward PCB placement.
• Leakage Current — Specified leakage current 1890 µA, measured per product conditions to aid in power-loss budgeting.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly workflows.

Typical Applications

• Switching Power Supplies — Output and bulk filtering in SMPS where low impedance and high ripple capability help stabilize voltage rails.
• General-Purpose Power Filtering — Decoupling and smoothing for industrial and electronic equipment requiring robust, long-life electrolytic capacitance.
• Power Conversion Modules — Energy storage and ripple suppression in DC–DC converters and power supply modules operating up to 105 °C.

Unique Advantages

• Designed for High-Ripple Environments — Dual ripple-current ratings (120 Hz and 200 kHz) provide clear, application-relevant data for both low- and high-frequency converter designs.
• Long Endurance at Elevated Temperature — 5000-hour rated life at 105 °C supports deployment in systems with sustained thermal stress.
• Predictable Electrical Loss — Specified tan δ and leakage current figures enable accurate thermal and efficiency calculations for power designs.
• Compact Through-Hole Form Factor — φ18 × 25 mm radial can with industry-standard lead spacing simplifies retrofits and PCB layouts for through-hole assemblies.
• RoHS Compliant — Meets environmental requirements for lead-free manufacturing and end-product compliance needs.
