UHE0J331MED

The UHE0J331MED from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHE series, providing 330 µF capacitance at a 6.3 V rated voltage. Designed as a compact, polarized, general-purpose capacitor, it targets applications that require a small footprint and measurable ripple-handling capability in a radial, can-style package.

Key attributes include a miniature φ6.3 × 11 mm package, an operating temperature range of −40 °C to 105 °C, RoHS compliance, and a specified endurance of 4000 hours at elevated temperature.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a tolerance of −20% to +20% and a rated voltage of 6.3 V for low-voltage power rails.
• Low-loss Electrical Performance — Tangent of loss angle (tanδ) specified at 0.22 (at 20 °C, 120 Hz) to characterize AC loss in the intended frequency band.
• Ripple Current Capability — Low-frequency ripple current of 238 mA at 120 Hz and high-frequency ripple current of 340 mA at 10 kHz, enabling filtering and ripple handling across a range of frequencies.
• Leakage Current — Measured leakage current of 20.79 µA, useful for estimating standby and bias losses in low-voltage circuits.
• Temperature & Lifetime — Rated for operation from −40 °C to 105 °C with an endurance rating of 4000 hours at 105 °C.
• Compact Radial Package — Small can-style radial package with physical dimensions φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm), and available in bulk or bag packing.
• Regulatory Compliance — RoHS compliant to support restricted-substance requirements.

Typical Applications

• General Purpose Electronics — Suited for general-purpose designs that require a compact polarized capacitor with 330 µF capacitance at 6.3 V.
• Power Rail Filtering — Use where low-voltage smoothing, decoupling, and ripple mitigation are required within the specified ripple current limits.
• Compact Modules — Fits space-constrained assemblies that need a radial-lead can-style capacitor (φ6.3 × 11 mm) with defined lead spacing.

Unique Advantages

• Space-efficient form factor: The φ6.3 × 11 mm radial can enables integration into compact PCBs and tight component layouts.
• Frequency-versatile ripple handling: Specified ripple current at both 120 Hz (238 mA) and 10 kHz (340 mA) supports filtering across low and higher frequency domains.
• Wide operating temperature: Rated from −40 °C to 105 °C to accommodate designs exposed to a broad thermal range.
• Clear electrical characterization: Specified tanδ, leakage current, and tolerance make it straightforward to model loss, leakage, and capacitance margins in designs.
• RoHS compliance: Built to meet restricted-substance requirements for environmentally conscious assemblies.
