UPJ2E330MHD

The UPJ2E330MHD is a radial-lead aluminum electrolytic capacitor offering 33 µF capacitance at a 250 V rating. It belongs to Nichicon's UPJ series, a low-impedance family designed for use in switching power supplies and general-purpose power filtering.

With a wide operating range to 105°C, specified ripple currents at both low and high frequencies, and a 5000-hour endurance at 105°C, this part targets designs that require reliable high-voltage decoupling and bulk storage in compact radial-can packaging.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance rated for 250 V DC, suitable for high-voltage power rails and DC bus decoupling.
• Low Impedance Design — UPJ-series construction optimized for switching power supply applications, improving ripple handling and transient response.
• Endurance at Elevated Temperature — Rated for 5000 hours of load life at 105°C, providing extended reliability under high-temperature operating conditions.
• Ripple Current Specification — Low-frequency ripple current 180 mA (120 Hz) and high-frequency ripple current 288 mA (1 kHz), enabling predictable performance across common switching and line frequencies.
• Leakage and Dissipation — Leakage current specified at 430 µA and tanδ (dissipation factor) of 0.2 measured at 20°C, 120 Hz, for predictable loss characteristics.
• Temperature Range — Operates from −40°C to +105°C to cover a broad set of industrial and power-electronics environments.
• Radial Can Package — φ16 × 25 mm can with 7.5 mm lead spacing for through-hole radial mounting and straightforward PCB placement.
• Packaging Options — Bulk (no terminal forming) or bag packing to suit assembly and procurement preferences.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Bulk and output filtering where low impedance and long high-temperature life improve regulation and reliability.
• DC-DC Converters — Decoupling and energy storage on high-voltage converter rails using the 250 V rating.
• Industrial Power Electronics — Filtering and smoothing in control power supplies and power modules operating up to 105°C.
• General-Purpose Power Filtering — Through-hole designs requiring a compact radial electrolytic with defined ripple and leakage characteristics.

Unique Advantages

• Designed for Switching Environments: UPJ-series low-impedance characteristics make this capacitor well-suited to switching power supplies and converter outputs.
• High-Temperature Endurance: 5000 hours at 105°C provides predictable lifetime performance in elevated-temperature installations.
• High Voltage Capability: 250 V rating enables use on higher-voltage DC rails where lower-voltage capacitors are unsuitable.
• Measured Ripple Performance: Specified ripple currents at 120 Hz and 1 kHz help designers size components against both line-frequency and switching-frequency stress.
• Compact Radial Form Factor: φ16×25 mm can and 7.5 mm lead spacing balance board space and capacitance for through-hole assemblies.
• Regulated Loss and Leakage: Dissipation factor and leakage current values (tanδ = 0.2, ILeak = 430 µA) support thermal and efficiency planning in power designs.
