UPJ1E331MPD6

The UPJ1E331MPD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering 330 µF capacitance at a 25 V rating. It combines a compact φ10 × 16 mm can with a 5.0 mm lead spacing for through-hole mounting and general-purpose power applications.

Designed for power filtering and decoupling in electrical systems, this capacitor delivers low impedance characteristics and long-term reliability with a documented endurance of 5000 hours at +105°C, making it suitable for sustained high-temperature operation in demanding electronics.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance at a rated voltage of 25 V and ±20% tolerance (120 Hz, 20°C).
• Low Impedance Construction: UPJ series design emphasizes low impedance for improved power performance and stable decoupling in switching environments.
• High Temperature Endurance: Rated for 5000 hours at +105°C under rated ripple and DC bias conditions, supporting reliable long-term operation.
• Ripple Current Capability: Low-frequency ripple current of 333.5 mA (120 Hz) and high-frequency ripple current of 575 mA (200 kHz) for effective noise suppression across frequency bands.
• Leakage & Loss Angle: Specified leakage current of 247.5 µA and tan δ measured at 20°C, 120 Hz (series tan δ max. for 25 V = 0.14), enabling predictable electrical behavior.
• Mechanical & Mounting: Radial lead can (φ10 × 16 mm) with 5.0 mm lead spacing and 0.5 mm spacing tolerance; available in bulk (no terminal forming) or bag packing.
• Wide Operating Temperature: −55°C to +105°C operating range suitable for many industrial and commercial applications.
• Environmental Compliance: RoHS compliant construction.

Typical Applications

• Switching Power Supplies: Low impedance and high ripple-current capacity make it well suited for input/output smoothing and bulk decoupling in SMPS designs.
• Power Modules and DC–DC Converters: Compact radial package and rated endurance at 105°C support sustained operation in power conversion modules.
• Industrial Control Equipment: Robust temperature range and long life make it a fit for power filtering in industrial electronics and control systems.

Unique Advantages

• Documented high-temperature lifetime: 5000 hours at +105°C provides a clear reliability baseline for thermal-stressed designs.
• Dual-band ripple handling: Specified ripple currents at both 120 Hz and 200 kHz enable designers to size bulk and high-frequency decoupling from a single part.
• Predictable electrical behavior: Defined leakage current and tan δ measurement conditions ensure repeatable performance during qualification and test.
• Compact, through-hole form factor: φ10 × 16 mm can and 5.0 mm lead spacing deliver a space-efficient solution for through-hole assemblies.
• RoHS compliant: Meets RoHS requirements for environmental compliance in commercial and industrial products.
