UPJ1V181MPD

The UPJ1V181MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series. It delivers 180 µF at 35 V in a compact φ8 × 20 mm can designed for through-hole mounting.

Engineered for low impedance and reliable operation, this part is specified for general-purpose use and is highlighted in series documentation as suitable for switching power supplies. Key attributes include a wide operating temperature range, defined ripple current ratings at both low and high frequencies, and a 3000-hour endurance at 105°C for the φ8 case size.

Key Features

• Capacitance & Rated Voltage: 180 µF nominal capacitance at a rated voltage of 35 V with ±20% tolerance (120 Hz, 20°C).
• Low Impedance Design: UPJ series characteristic of low impedance for applications such as switching power supplies.
• Temperature and Endurance: Specified operating range −55°C to +105°C and endurance of 3000 hours at 105°C for the φ8 case size.
• Ripple Current (Dual-Frequency): Low-frequency ripple current 280.8 mA (120 Hz) and high-frequency ripple current 520 mA (200 kHz).
• Leakage and Dissipation Factor: Specified leakage current 189 µA and tan δ 0.12 (measured at 20°C, 120 Hz) for the 35 V rating.
• Package & Mounting: Radial lead, can-style package with dimensions φ8 × 20 mm and lead spacing 3.5 mm (lead spacing tolerance ±0.5 mm); available in bulk or bag packing.
• Compliance & Availability: RoHS compliant and listed as mass production status.

Typical Applications

• Switching Power Supplies: Low-impedance design and dual-frequency ripple ratings make the capacitor suitable for energy storage and filtering in switching regulator outputs.
• General-Purpose Electronics: Specified for general-purpose use where a polarized electrolytic with 180 µF / 35 V is required.
• Through-Hole Assembly: Radial lead configuration and φ8 × 20 mm can facilitate insertion and soldering in through-hole board designs.

Unique Advantages

• Low-Impedance Performance: UPJ series low-impedance characteristics support tighter output ripple control in power conversion circuits.
• Defined High-Temperature Endurance: 3000-hour rating at 105°C for the φ8 case size provides a clear reliability metric for thermal environments.
• Dual-Frequency Ripple Specification: Separate ripple current ratings at 120 Hz and 200 kHz allow designers to evaluate performance across common frequency ranges.
• Compact Through-Hole Footprint: φ8 × 20 mm can with 3.5 mm lead spacing suits space-constrained board layouts that require through-hole components.
• Measured Electrical Parameters: Specified leakage current (189 µA) and tan δ (0.12 at 35 V) give quantifiable electrical behavior for design verification.
• Production-Ready Supply: RoHS compliance and mass-production status simplify procurement and regulatory planning.
