UPJ1A332MHD

The UPJ1A332MHD is an aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. It is part of Nichicon’s UPJ series, a low-impedance family intended for switching power supplies and related power-filtering uses.

With 3.3 mF capacitance at 10 V, a wide operating temperature range of -55°C to 105°C and a rated endurance of 5000 hours at 105°C, this component is aimed at designs that require bulk energy storage, ripple filtering and elevated-temperature reliability.

Key Features

• Low-impedance design — Series-level characterization identifies the UPJ family as low impedance, making this part suitable for switching power supply applications.
• Capacitance and voltage — 3300 µF at 10 V with ±20% tolerance provides substantial bulk capacitance for smoothing and decoupling in low-voltage power rails.
• High ripple current capability — Rated low-frequency ripple current of 1.764 A at 120 Hz and high-frequency ripple current of 1.96 A at 200 kHz to support converter and regulator loads.
• Measured dissipation factor — tanδ 0.23 measured at 20°C, 120 Hz, for designers assessing ESR-related losses and heat generation.
• Long endurance at elevated temperature — 5000 hours life at 105°C, supporting designs that require extended operation in warm environments.
• Leakage and polarization — Polarized capacitor with measured leakage current of 990 µA for initial leak-current budgeting.
• Radial lead package — Compact φ12.5 × 35.5 mm can with 5 mm lead spacing (±0.5 mm) for through-hole mounting and straightforward PCB layout.
• RoHS compliant — Meets RoHS requirements for restricted substances.
• Packaging options — Available in bulk (no terminal forming) and bag packing to match assembly and procurement preferences.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering in switching regulators where low impedance and ripple handling are required.
• DC‑DC Converters — Energy storage and ripple suppression for converter outputs and intermediate rails.
• Industrial Power Modules — Local bulk capacitance in control modules and power distribution boards operating across -55°C to 105°C.
• Consumer Power Electronics — Bulk filtering and decoupling in low-voltage consumer power supplies and adapters.

Unique Advantages

• Designed for power applications — Low-impedance UPJ series construction tailored to switching power supply requirements.
• High ripple tolerance — Specified ripple currents at both 120 Hz and 200 kHz help reduce thermal stress and extend service life in ripple-rich environments.
• Extended high-temperature life — 5000 hours at 105°C provides predictable endurance for designs exposed to sustained elevated temperatures.
• Clear electrical baseline — Measured tanδ and leakage current values allow straightforward thermal and leakage budgeting during design.
• Compact radial package — φ12.5 × 35.5 mm can and 5 mm lead spacing balance capacitance density with ease of through-hole assembly.
• RoHS compliance — Simplifies regulatory alignment for products shipping to RoHS-regulated markets.
