UHD1C332MHD

The UHD1C332MHD is a high-reliability miniature aluminum electrolytic capacitor in a radial lead can targeted for general-purpose electronic designs. It combines a large capacitance (3300 µF) with low impedance and high ripple-current capability to support smoothing and energy-storage roles in compact assemblies.

Designed for demanding thermal and ripple conditions, this Nichicon UHD series part offers a 16 V rating, wide operating temperature range and an endurance specification suitable for long-life applications.

Key Features

• Capacitance & Voltage — 3300 µF nominal capacitance at a rated voltage of 16 V with a tolerance of -20% to +20%.
• Low Loss (tan δ) — Dissipation factor (tan δ) of 0.20 measured at 20°C, 120 Hz, supporting efficient energy handling in AC ripple conditions.
• High Ripple Current — Low-frequency ripple current of 2.72 A (120 Hz) and high-frequency ripple current of 3.40 A (100 kHz) for improved performance under varying ripple spectra.
• Low Leakage — Leakage current specified at 528 µA, measured after 2 minutes at rated voltage and 20°C, supporting predictable bias performance.
• Robust Endurance — Rated for 5000 hours at 105°C, with capacitance change and tan δ limits defined for long-term reliability.
• Compact Radial Package — Can dimensions φ12.5 × 35.5 mm with 5.0 mm lead spacing and radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• Wide Temperature Range & Compliance — Operating from −40°C to +105°C and RoHS compliant for environmental compatibility.

Typical Applications

• General-purpose electronics — Energy storage and smoothing in circuits that require a high-capacitance, polarized capacitor rated for 16 V.
• Pwr ripple suppression — Filtering and ripple current handling where both low- and high-frequency ripple currents must be managed.
• Compact through-hole designs — Where a small can (φ12.5 × 35.5 mm) and radial lead mounting are preferred for board-level assemblies.

Unique Advantages

• High ripple handling — Specified ripple currents at 120 Hz and 100 kHz (2.72 A and 3.40 A) allow the capacitor to address varied ripple profiles without overrating components.
• Long endurance at elevated temperature — 5000 hours at 105°C provides predictable lifetime performance for thermal-stressed designs.
• Compact form factor — φ12.5 × 35.5 mm package delivers 3300 µF in a small radial can suitable for space-constrained boards.
• Low leakage and defined DF — 528 µA leakage current and tan δ = 0.20 support stable bias behavior and efficient operation.
• RoHS compliant — Meets RoHS requirements for environmental regulatory compatibility.
• Production-ready — Listed as mass production status with bulk and bag packing options for volume assembly flexibility.
