URZ1A332MHD

The URZ1A332MHD is a miniature, low-profile aluminum electrolytic capacitor from Nichicon’s URZ series. It is a polarized radial-lead, standard-type electrolytic designed for general-purpose power applications where compact bulk capacitance is required.

Key attributes include a 3300 µF capacitance at 10 V, an extended operating temperature range of −55°C to +105°C, and endurance rating of 1000 hours at 105°C. Status: End Of Life.

Key Features

• Capacitance & Rated Voltage — 3300 µF nominal capacitance, rated at 10 V with capacitance tolerance −20% to +20% (measured at 120 Hz, 20°C).
• Compact, Low-Profile Package — Case size φ16 × 15 mm (D × L) provides high capacitance in a small radial-can footprint; seated height corresponds to the 15 mm length for space-constrained designs. Lead spacing is 7.5 mm with a tolerance of ±0.5 mm.
• Wide Temperature Range & Endurance — Specified for operation from −55°C to +105°C with life/endurance of 1000 hours at 105°C, enabling use across a broad thermal envelope.
• Ripple Current Capability — Low-frequency ripple current of 940 mA at 120 Hz and high-frequency ripple current of 1.081 A at 10 kHz, supporting smoothing and decoupling in power circuits.
• Electrical Loss and Leakage — Measured tan δ (DF) of 0.28 (20°C, 120 Hz) and leakage current of 990 µA, useful for evaluating ESR-related heating and standby current impact.
• Mounting & Packaging — Radial lead (polarized) configuration for through-hole mounting; shipping options include bulk (no terminal forming) and bag packing.

Typical Applications

• General-purpose power filtering — Bulk capacitance and ripple handling for low-voltage DC power rails within the specified temperature range.
• Energy storage for backup circuits — Compact 3300 µF capacity suitable where short-term energy hold-up is required in a small radial-can form factor.
• Smoothing in DC/DC converter outputs — Ripple current ratings and low-profile packaging support smoothing and decoupling in constrained layouts.

Unique Advantages

• High capacitance in a compact footprint: 3300 µF in a φ16 × 15 mm case provides significant bulk capacitance where board space is limited.
• Wide operating temperature: −55°C to +105°C rating supports designs exposed to broad thermal conditions without derating functionality.
• Designed endurance: 1000 hours at 105°C allows designers to plan for long-term performance under elevated temperature stress.
• Measurable ripple capability: Specified ripple currents at both low and high frequencies (940 mA at 120 Hz, 1.081 A at 10 kHz) enable straightforward thermal and ripple budgeting.
• Through-hole, radial-lead simplicity: Radial lead form factor and standard lead spacing (7.5 mm) simplify PCB layout and assembly for legacy or mixed-technology designs.
