UHW2A330MPD

The UHW2A330MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can. Designed as part of Nichicon’s UHW series, it delivers low impedance at high frequency and elevated ripple-current capability in a compact φ8 × 11.5 mm package.

Suited for general-purpose electronic designs, this polarized capacitor provides a combination of high operating voltage (100 V), extended endurance (10,000 hours at 105°C), and packaging options for bulk or bagged assembly handling.

Key Features

• Capacitance & Voltage — 33 µF rated capacitance with a 100 V rated voltage and tolerance of −20% to +20%.
• Miniature Radial Package — φ8 × 11.5 mm can with radial lead mounting and 3.5 mm lead spacing (±0.5 mm), suitable for compact board layouts.
• High Ripple-Current Capability — Low-frequency ripple current 380 mA (120 Hz) and high-frequency ripple current 950 mA (100 kHz) to support demanding AC superposition conditions.
• Low Loss / Low Impedance — Dissipation factor tanδ = 0.08 (measured at 20°C, 120 Hz) and impedance of 1.3 Ω to help minimize heating and voltage drop under AC ripple.
• High Reliability & Endurance — Rated lifetime 10,000 hours at 105°C with specified limits on capacitance change, tanδ, and leakage after the endurance test.
• Leakage Current — Low leakage current specified at 33 µA to reduce standby losses in DC circuits.
• Environmental Compliance & Production Status — RoHS compliant and currently in mass production; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Power Supplies — General-purpose smoothing and decoupling where a compact, high-voltage capacitor with sustained ripple capability is required.
• Industrial Electronics — Designs that demand extended high-temperature endurance and stable performance at elevated ripple currents.
• Consumer and Commercial Equipment — Space-constrained circuits requiring polarized bulk capacitance with low impedance at higher frequencies.

Unique Advantages

• Compact High-Voltage Solution: 33 µF at 100 V in a φ8 × 11.5 mm case provides substantial voltage headroom in a small footprint.
• Designed for Ripple Performance: Specified low- and high-frequency ripple currents (380 mA @120 Hz, 950 mA @100 kHz) reduce heating and extend service life under AC stress.
• Predictable Loss Characteristics: Low tanδ (0.08 at 20°C, 120 Hz) and 1.3 Ω impedance make behavior under AC conditions easier to model during design.
• Long Endurance at Elevated Temperature: 10,000 hours rated lifetime at 105°C supports reliable operation in demanding thermal environments.
• Manufacturing-Ready Packaging: Available in bulk (no terminal forming) or bag packing for flexible handling in assembly processes.
• Regulatory Compliance: RoHS-compliant construction supports environmental and regulatory requirements.

Why Choose UHW2A330MPD?

The UHW2A330MPD combines a compact radial-can package with high-voltage rating, strong ripple capability, and long-term thermal endurance—providing a reliable capacitor option for general-purpose electronics where space, durability, and predictable AC performance matter. Its low loss (tanδ) and specified impedance help designers control dissipation and maintain stable operation across frequency ranges.

This part is well suited for engineers and procurement teams specifying capacitors for compact power assemblies, industrial control electronics, or consumer systems that require a robust, RoHS-compliant electrolytic with available bulk or bag packing for production integration.
