UPJ1E181MPD6

The UPJ1E181MPD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a polarized, high-reliability component designed for low-impedance power applications and general-purpose circuit use.

Engineered for long operating life and compact packaging, this part delivers 180 µF at 25 V with performance characteristics targeted at switching power supplies and other power-filtering roles where low impedance and sustained endurance are required.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance rated at 25 V with capacitance tolerance of −20% to +20%.
• Low Loss / Low Impedance — tan δ (DF) = 0.14 measured at 20°C, 120 Hz, supporting lower ESR behavior for power applications.
• Ripple Current Capability — Low-frequency ripple current 213.3 mA at 120 Hz and high-frequency ripple current 395 mA at 200 kHz, suitable for bulk filtering in switching supplies.
• Leakage Current — Specified leakage current of 135 µA after standard application conditions.
• High Endurance — Rated life of 5000 hours at 105°C (high-reliability UPJ series endurance specification).
• Temperature Range — Wide operating range from −55°C to +105°C for deployment across varied environments.
• Compact Radial Package — Can-style radial package, size φ10 × 12.5 mm (D × L) with 5.0 mm lead spacing (±0.5 mm) and radial lead mounting.
• Packaging & Production Status — Available in bulk (no terminal forming) and bag packing; mass production status.
• RoHS Compliance — Material compliance noted for regulated substance requirements.

Typical Applications

• Switching Power Supplies — Provides bulk filtering and low-impedance smoothing for DC rails in switching supply designs.
• General-Purpose Power Decoupling — Supports energy storage and decoupling in a wide range of electronic assemblies labeled as general purpose.
• Compact Power Modules — Small radial form factor and 5 mm lead spacing suit space-conscious power modules and board-level power sections.

Unique Advantages

• Balanced Performance and Size: 180 µF at 25 V in a φ10 × 12.5 mm can provides substantive capacitance without a large board footprint.
• Designed for Low Impedance: Specified tan δ and ripple current ratings indicate suitability where reduced AC losses and stable ripple handling are required.
• Long-Term Reliability: 5000 hours at 105°C endurance rating supports designs requiring sustained high-temperature operation.
• Predictable Electrical Characteristics: Specified leakage current (135 µA) and ±20% tolerance help simplify power-budgeting and design margins.
• Radial-Lead Convenience: Standard 5 mm lead spacing and radial mounting ease through-hole assembly and retrofit into existing designs.
• Regulatory Compliance: RoHS compliance supports deployment in regions and products requiring restricted-substance adherence.
