UEP0J330MDD

The UEP0J330MDD is a bi-polarized aluminum electrolytic capacitor from Nichicon's UEP series, designed for general-purpose electronic applications. It combines a compact radial-can package with a wide operating temperature range and defined endurance characteristics for reliable performance in temperature-challenging environments.

Key value propositions include bi-polarized construction for polarity-independent use, a compact φ5 × 11 mm footprint with 2 mm lead spacing, and rated electrical characteristics tuned for low-voltage general-purpose circuits.

Key Features

• Electrical Core — 33 µF nominal capacitance at a rated voltage of 6.3 V with ±20% tolerance (120 Hz, 20°C).
• Bi-Polar Construction — Bipolarized design permits use without a fixed polarity, suitable for circuits that require polarity-independent capacitance.
• Loss and Leakage — Maximum tan δ of 0.24 (6.3 V, 120 Hz, 20°C) and measured leakage current of 62.37 µA for predictable loss and leakage behavior.
• Ripple Handling — Specified ripple current of 46 mA at 120 Hz and 92 mA at 10 kHz, with frequency coefficients applicable for the 10–47 µF range as provided in the series data.
• Wide Temperature Range — Rated for operation from −55°C to +105°C to support designs exposed to wide ambient conditions.
• Reliability & Endurance — 1000-hour rated life at 105°C with polarity inversion every 250 hours per endurance specification.
• Compact Radial Package — Radial lead can package, physical dimensions approximately 0.5 × 1.1 cm (φ5 × 11 mm), with 2 mm lead spacing; bulk/bag packing.
• Environmental Compliance — RoHS compliant.
• Availability Status — Product is listed as End of Life; please request availability and replacement guidance when sourcing.

Typical Applications

• General-purpose electronics — Compact bipolar capacitor for general-purpose circuit functions where polarity independence and a small footprint are required.
• Temperature-challenged systems — Suitable for designs that require components rated from −55°C to +105°C and defined 1000 h endurance at high temperature.
• AC/signal circuits — Bipolar construction supports use in circuits where polarity may invert or where polarity-independent decoupling is needed.

Unique Advantages

• Polarity-independent operation: Bipolarized design eliminates orientation constraints in circuits where polarity may change.
• Compact radial can footprint: φ5 × 11 mm size and 2 mm lead spacing save board area while retaining through-hole radial lead mounting.
• Wide operating temperature: −55°C to +105°C rating expands usable environments compared with standard-temperature components.
• Defined endurance at high temperature: 1000 hours at 105°C with specified post-test limits for capacitance, tan δ and leakage current support predictable life expectation.
• Measured performance metrics: Specified tan δ (0.24) and measured leakage current (62.37 µA) provide quantifiable electrical behavior for design verification.
• RoHS compliance: Meets RoHS directive requirements for lead-free assembly environments.
