UVZ1A333MRD

The UVZ1A333MRD is a polarized aluminum electrolytic capacitor in a radial can package, offering 33,000 µF capacitance at a 10 V rating. Its combination of very high capacitance, wide operating temperature range and substantial ripple-current capability makes it suitable for general-purpose low-voltage power designs that require bulk energy storage and smoothing.

This part is RoHS compliant and rated for endurance of 2000 hours at 105°C. Packaging options include bulk (no terminal forming) and bag packing. Note: product status is End Of Life.

Key Features

• High Capacitance — 33,000 µF nominal capacitance provides substantial bulk energy storage for low-voltage rails and smoothing applications.
• Rated Voltage — 10 V working voltage suited for modern low-voltage power systems.
• Wide Temperature Range — Operates from −55°C to 105°C, supporting a broad range of environmental conditions.
• Endurance — Specified for 2000 hours at 105°C under rated voltage, providing predictable life characteristics for high-temperature operation.
• High Ripple Current Capability — 3.25 A at 120 Hz (low frequency) and 3.7375 A at 10 kHz (high frequency) to handle substantial AC stress and reduce thermal buildup.
• Physical Package — Radial lead can, size φ22 × 50 mm, lead spacing 10 mm (±0.5 mm), for through-hole mounting and easy PCB integration.
• Electrical Characteristics — Capacitance tolerance −20% to +20%; leakage current specified at 9,900 µA; measured tanδ (DF) 0.88 at 20°C, 120 Hz.
• Compliance — RoHS compliant.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible assembly and inventory handling.

Typical Applications

• Power-supply bulk storage — Provides large capacitance for hold-up and smoothing on low-voltage power rails in power-supply designs.
• DC bus and rail stabilization — Used to stabilize voltage rails and absorb transient loads where high capacitance and ripple capability are required.
• Industrial control power modules — Supports energy buffering and decoupling in control and automation equipment that operates across a wide temperature range.

Unique Advantages

• Large capacitance in a compact radial can: 33,000 µF in a φ22 × 50 mm package maximizes energy density for through-hole designs.
• Designed for harsh temperatures: −55°C to 105°C rating extends usability across demanding environmental conditions.
• Robust ripple handling: High low- and high-frequency ripple-current ratings reduce heating and help maintain performance under AC stress.
• Predictable high-temperature life: 2000 hours endurance at 105°C gives engineers a defined baseline for lifespan planning.
• Flexible procurement options: Bulk and bag packing accommodate different assembly and inventory workflows.
• Regulatory compliance: RoHS status supports environmentally constrained designs.

Why Choose UVZ1A333MRD?

The UVZ1A333MRD combines high capacitance, substantial ripple-current capability and a wide operating temperature window in a standard radial can, making it a practical choice for general-purpose low-voltage power designs that require reliable bulk energy storage. Its defined endurance at 105°C and RoHS compliance help simplify lifecycle and environmental planning for engineering and procurement teams.

Because the part is listed as End Of Life, specify it where bill-of-material continuity or existing-design replacement is required, and verify inventory and lifecycle constraints when planning new production runs.
