UPJ1E181MPD

The UPJ1E181MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, designed for low-impedance power filtering in switching power supplies and general-purpose power circuits. It delivers 180 µF at a 25 V rating in a compact φ8×15L can with 3.5 mm lead spacing for through‑hole PCB mounting.

This part combines high ripple capability and wide operating temperature range (−55 °C to +105 °C) with a 3000-hour endurance at 105 °C for φ8 case sizes, making it suitable for sustained operation in demanding power-electronics environments.

Key Features

• Capacitance & Voltage: 180 µF rated at 25 V for bulk and decoupling applications where moderate capacitance and voltage are required.
• Low Impedance Construction: UPJ series low-impedance design optimized for switching power supplies and DC‑DC converter output smoothing.
• Ripple Current Capability: Handles 210.6 mA at 120 Hz (low frequency) and 390 mA at 200 kHz (high frequency), supporting both mains‑frequency and high‑frequency ripple environments.
• Loss Characteristics: tan δ = 0.14 measured at 20 °C, 120 Hz (rated voltage condition), supporting predictable ESR-related behavior in filter designs.
• Leakage Current: Specified leakage current of 135 µA for reliable bias performance after voltage application.
• Endurance & Temperature Range: Rated for 3000 hours at 105 °C (φ8 case) and operable from −55 °C to +105 °C for long-term thermal stability.
• Radial Through‑Hole Package: φ8×15L can with 3.5 mm lead spacing (tolerance 0.5 mm), sold in bulk/no-terminal-forming or bag packing for standard assembly workflows.
• RoHS Compliant: Meets RoHS requirements for restricted substances.

Typical Applications

• Switching Power Supplies: Output filtering and bulk capacitance where low impedance and sustained ripple handling improve voltage regulation stability.
• DC‑DC Converters: Energy storage and decoupling on converter outputs and intermediate rails to support transient loads.
• General Power Filtering: Smoothing and noise suppression in industrial and consumer electronics requiring a compact radial electrolytic solution.

Unique Advantages

• Low-impedance performance: Designed to reduce AC voltage ripple in switching environments, translating to improved regulator stability.
• Compact radial can: φ8×15L size with 3.5 mm lead spacing provides a space-efficient through‑hole option for power boards.
• Wide temperature tolerance: −55 °C to +105 °C operation supports designs exposed to broad ambient conditions.
• High-frequency ripple handling: Specified ripple current at 200 kHz (390 mA) helps manage high-frequency switching noise and losses.
• Proven endurance at elevated temperature: 3000-hour rating at 105 °C for φ8 case sizes provides predictable lifetime planning for long-term deployments.
• RoHS compliance: Simplifies environmental compliance for product designs and deployments.
