UPJ1J181MPD

The UPJ1J181MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, optimized for low impedance performance in power applications. This specific part provides 180 µF capacitance at a 63 V rating in a compact φ10 × 30.5 mm can with 5 mm lead spacing.

Designed for general-purpose and power-supply use, the device combines a wide operating temperature range (−55 °C to +105 °C) with a long endurance specification of 5000 hours at 105 °C, making it suitable for robust power filtering and decoupling in industrial and electronic equipment.

Key Features

• Capacitance & tolerance — 180 µF with a tolerance of −20% to +20% at 120 Hz, 20 °C.
• Rated voltage — 63 V DC rating suitable for higher-voltage power rails.
• Low loss (tan δ) — tanδ specified at 0.08 (measured at 20 °C, 120 Hz) supporting low-impedance behavior.
• Ripple current capability — Low-frequency ripple current 426.6 mA at 120 Hz and high-frequency ripple current 790 mA at 200 kHz, enabling handling of AC ripple in switching supplies.
• Leakage current — Specified leakage current of 340.2 µA after voltage application, allowing predictable bias behavior.
• High-temperature endurance — Rated for 5000 hours at 105 °C when used under the specified conditions.
• Package & mounting — Radial-lead can (φ10 × 30.5 mm), lead spacing 5 mm (±0.5 mm), available in bulk or bag packing.
• Operating range & compliance — Operates from −55 °C to +105 °C and is RoHS compliant.

Typical Applications

• Switching power supplies — Low-impedance characteristics and specified ripple current make this capacitor suitable for input/output filtering and bulk decoupling in switching regulators.
• Power management modules — 63 V rating and 180 µF capacitance support energy storage and voltage stabilization in power-conversion circuits.
• Industrial and general-purpose electronics — Wide temperature range and long-life endurance fit demanding environments and continuous-operation systems.

Unique Advantages

• Long high-temperature life: 5000 hours at 105 °C provides predictable longevity for sustained elevated-temperature operation.
• Low-impedance performance: tanδ = 0.08 (63 V, 120 Hz) indicates reduced loss and improved AC behavior for power applications.
• Dual-frequency ripple capability: Explicit ripple ratings at 120 Hz (426.6 mA) and 200 kHz (790 mA) support both mains-frequency smoothing and high-frequency switching environments.
• Compact radial can: φ10 × 30.5 mm package with 5 mm lead spacing simplifies layout for through-hole power designs.
• Predictable leakage: Specified leakage current (340.2 µA) helps engineers budget bias currents in sensitive circuits.
• RoHS compliant: Meets environmental directives to support regulatory requirements in many markets.
