UVZ1C333MRD

The UVZ1C333MRD is a radial-lead aluminum electrolytic capacitor from Nichicon's UVZ series, offering high bulk capacitance in a compact radial can package. With a rated capacitance of 33 mF (33,000 µF) at 16 V and a wide operating temperature range, it is intended for general-purpose electronic applications that require significant energy storage and stable performance across temperature extremes.

Key electrical characteristics include low-frequency and high-frequency ripple current capability, a defined leakage current, and endurance specified at elevated temperature. Note: this part is currently listed as End Of Life.

Key Features

• High Capacitance (33 mF / 33,000 µF) — Provides substantial bulk energy storage for general-purpose applications where load smoothing or charge buffering is required.
• Rated Voltage 16 V — Designed and specified for 16 V systems.
• Wide Temperature Range — Operates from −55°C to +105°C to support use across harsh and varied thermal environments.
• Ripple Current Capability — Low-frequency ripple current of 3.45 A (120 Hz) and high-frequency ripple current of 3.967 A (10 kHz) for handling AC ripple in power circuits.
• Endurance — Rated lifetime of 2000 hours at 105°C, with capacitance and leakage limits defined for end-of-life performance.
• Leakage Current — Specified leakage current of 15,840 µA, enabling predictable DC leakage behavior for design margining.
• Mechanical / Package — Radial, can-style package sized φ25 × 50 mm with 12.5 mm lead spacing (±0.5 mm), suitable for through-hole mounting and straightforward assembly.
• Compliance & Packaging Options — RoHS-compliant; available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.

Typical Applications

• General-purpose electronics — Provides large-capacitance storage for designs that require stable capacitance across −55°C to +105°C operating range.
• Power supply subsystems — Supports bulk filtering and ripple handling in 16 V DC power rails, leveraging its 3.45 A (120 Hz) and 3.967 A (10 kHz) ripple current ratings.
• Industrial and temperature-challenged equipment — Suited for applications that demand operation over a wide temperature span and a defined endurance at elevated temperature.

Unique Advantages

• Large bulk capacitance in a compact can — 33,000 µF in a φ25 × 50 mm package reduces board area compared with multiple smaller capacitors.
• Wide operating temperature window — −55°C to +105°C supports designs exposed to extreme cold and heat without changing the capacitor footprint.
• Defined high-temperature endurance — 2000 hours at 105°C gives clear expectations for life and aging in elevated-temperature applications.
• Dual-frequency ripple handling — Measured ripple current specifications at both 120 Hz and 10 kHz help designers size capacitors for both mains-derived and higher-frequency switching environments.
• Through-hole radial package — φ25 × 50 mm radial can and 12.5 mm lead spacing provide mechanical robustness and easy replacement in repair or prototyping scenarios.
• RoHS compliant with flexible packing — Environmentally compliant material set and choice of bulk or bag packing for manufacturing convenience.
