UPA0J332MHD

The UPA0J332MHD is a miniature, radial-lead aluminum electrolytic capacitor designed for switching power supplies and general-purpose power applications. It delivers low impedance and high ripple-current capability in a compact radial can package, making it suitable where board space and reliable power filtering are priorities.

Key Features

• Capacitance & Voltage — 3.3 mF capacitance rated at 6.3 V for bulk energy storage and decoupling in low-voltage power rails.
• Low Impedance — Specified impedance of 58 mOhm to minimize voltage drop under load and improve transient response.
• High Ripple Current — Rated ripple current of 1.607 A at 120 Hz and 1.89 A at 10 kHz to handle switching supply ripple across common frequencies.
• Compact Radial Can — Radial lead mounting with 5 mm lead spacing and a compact footprint (L: 2 × D: 1.25 cm) for through-hole assembly where space is limited.
• Wide Temperature & Endurance — Operating range −55°C to +105°C with a lifetime rating of 5000 hours at 105°C.
• Polarized Design — Polar electrolytic construction for standard DC power supply applications.
• RoHS Compliant — Meets RoHS directive requirements for environmental compliance.

Typical Applications

• Switching Power Supplies — Bulk and ripple filtering where low impedance and high ripple capability improve regulator stability and efficiency.
• General-Purpose Power Modules — Energy storage and smoothing in low-voltage power rails for industrial and consumer electronics.
• Power Filtering Across Frequencies — Handles ripple from low (120 Hz) to high (10 kHz) frequency components thanks to specified ripple current ratings.

Unique Advantages

• Compact footprint with strong performance — Provides 3.3 mF capacitance and low impedance in a small radial can (L: 2 × D: 1.25 cm), helping reduce board space without sacrificing filtering capability.
• Measurable low impedance — 58 mOhm impedance supports lower voltage ripple and better transient response in DC power systems.
• High ripple handling across frequencies — Specified ripple currents at 120 Hz and 10 kHz ensure the capacitor can manage switching-generated ripple in typical supply designs.
• Designed for harsh environments — Wide −55°C to +105°C operating range and 5000 hours endurance at 105°C provide predictable lifetime under elevated temperature stress.
• Through-hole radial mounting — 5 mm lead spacing and radial lead construction simplify retrofit and prototyping workflows on standard PCBs.
• Regulatory compliance — RoHS compliance supports environmentally conscious designs and regulatory needs.
