UPJ1E332MHD

The UPJ1E332MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series, configured as a radial lead can. With a rated capacitance of 3300 µF at 25 V and a compact φ16 × 35.5 mm case, it targets power filtering and energy storage in general-purpose electronic designs.

Designed for low impedance and high ripple handling, the UPJ1E332MHD is well suited for switching power supplies and other power-conversion circuits that require robust smoothing and bulk decoupling across a wide temperature range.

Key Features

• Capacitance & Voltage: 3300 µF (3.3 mF) nominal capacitance with a rated voltage of 25 V and tolerance of -20% to +20%, providing substantial bulk storage for power rails.
• Low Loss (DF): Measured tangent of loss angle (tanδ) of 0.26 at 20°C, 120 Hz, indicating the capacitor’s dissipation factor under standard test conditions.
• High Ripple Current Capability: Low-frequency ripple current 2.169 A (120 Hz) and high-frequency ripple current 2.41 A (200 kHz), supporting demanding switching-power environments.
• Leakage Current: Specified leakage current of 2475 µA, measured under rated conditions.
• Long Endurance: Rated for 5000 hours at 105°C, reflecting the UPJ series’ high-reliability endurance for sustained elevated-temperature operation.
• Wide Temperature Range: Operating range from -55°C to +105°C for use across varied environmental conditions.
• Package & Mounting: Radial lead, polarized aluminum can (φ16 × 35.5 mm) with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• RoHS Compliant: Conforms to RoHS requirements as specified in the product information.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output decoupling where high ripple current capability and low impedance are required.
• Power Conversion Modules: Energy storage and filtering in DC–DC converters and power regulator circuits.
• Industrial Power Electronics: Bulk filtering and transient absorption in general-purpose industrial power systems operating across -55°C to +105°C.
• General Purpose Electronics: DC rail smoothing and reservoir capacitance in consumer and commercial electronic equipment.

Unique Advantages

• High ripple handling: Rated ripple currents of 2.169 A (120 Hz) and 2.41 A (200 kHz) help maintain stable operation in switching environments.
• Extended high-temperature life: 5000-hour endurance at 105°C provides predictable long-term performance under sustained thermal stress.
• Significant bulk capacitance in a compact can: 3300 µF in a φ16 × 35.5 mm package delivers large energy storage without excessive board space.
• Wide operating temperature range: -55°C to +105°C supports deployment in environments with wide thermal variation.
• Radial-lead convenience: Standard lead spacing (7.5 mm ±0.5 mm) and polarized construction simplify through-hole assembly and replacement in existing designs.
• Regulatory compliance: RoHS compliance aligns with common environmental requirements.
