UPJ1C331MPD6

The UPJ1C331MPD6 from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UPJ series. It is a radial-lead, polarized can-type capacitor rated at 330 µF and 16 V, designed for applications that require low impedance and robust endurance.

As part of the UPJ series — characterized for low impedance and suitability for switching power supplies — this unit delivers long life and stable performance across a wide temperature range for general-purpose power filtering and decoupling.

Key Features

• Capacitance and Tolerance — 330 µF nominal capacitance with ±20% tolerance at 20°C, 120 Hz.
• Rated Voltage — 16 V DC rating for low-voltage power rails and decoupling applications.
• Low Loss / Dissipation Factor — tanδ = 0.16 (measured at 20°C, 120 Hz), indicating controlled equivalent series characteristics for improved ripple handling.
• High Ripple Current Capability — 278.4 mA at 120 Hz (low frequency) and 480 mA at 200 kHz (high frequency), supporting both mains-frequency and switching-frequency ripple demands.
• Leakage Current — Specified leakage current of 158.4 µA after 1 minute at rated voltage, facilitating predictable standby and bias behavior.
• Endurance and Temperature Range — Rated for 5000 hours at 105°C with operating range −55°C to +105°C, supporting long-term operation in elevated-temperature environments.
• Package and Mounting — Radial lead, can-style package with dimensions φ10 × 12.5 mm (L) and 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing; mass production status.
• Compliance — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low-impedance characteristics and high-frequency ripple current rating make it suitable for input/output smoothing and bulk decoupling in switch-mode power supplies.
• Power Filtering and Decoupling — Useful for general-purpose power rail stabilization and noise suppression on low-voltage DC lines.
• Industrial and Consumer Electronics — Designed for long-life operation at elevated temperatures, appropriate for power circuitry in industrial control and consumer devices.

Unique Advantages

• Long High‑Temperature Endurance — 5000 hours at 105°C provides predictable life performance for designs exposed to sustained high temperatures.
• Dual-Frequency Ripple Performance — Specified ripple current at both 120 Hz and 200 kHz supports applications that experience both line-frequency and high-frequency switching ripple.
• Compact Radial Can — φ10 × 12.5 mm package with 5 mm lead spacing offers a small-footprint solution for through-hole designs needing reliable bulk capacitance.
• Measured Loss Characteristics — tanδ specified at 0.16 (20°C, 120 Hz) enables designers to assess dissipation and heating for thermal budgeting and reliability planning.
• Predictable Leakage — Defined leakage current value aids in low-current bias and standby system calculations.
• Regulatory Compliance — RoHS compliance supports designs targeting regulatory mandates for reduced hazardous substances.
