UEP1J3R3MDD

The UEP1J3R3MDD from Nichicon is a bi-polarized aluminum electrolytic capacitor supplied in a compact radial-can package. It delivers 3.3 µF capacitance at a 63 V rating and is designed for general-purpose electronic applications that require a small, leaded electrolytic with bi-polar characteristics.

Engineered for a wide operating temperature range and RoHS compliance, this radial-lead capacitor is suitable for designs that need stable performance from −55 °C to +105 °C and verified endurance across elevated temperatures.

Key Features

• Capacitance & Voltage — 3.3 µF rated capacitance at 63 V for compact energy storage and decoupling in small circuits.
• Bi-Polar Polarization — Bi-polar construction supports applications where polarity can invert and is exercised in endurance testing with polarity inversion.
• Wide Temperature Range — Specified to operate from −55 °C to +105 °C for use in temperature-challenging environments.
• Endurance — Rated for 1000 hours at 105 °C (endurance test with polarity inversion every 250 hours), with defined limits for capacitance change, tan δ and leakage current after test.
• Ripple Current Ratings — Low-frequency ripple current: 20 mA at 120 Hz; high-frequency ripple current: 40 mA at 10 kHz.
• Radial Lead, Compact Package — Radial lead mounting with 2 mm lead spacing and radial can package; physical size L: 1.1 cm × D: 0.5 cm for compact board layouts.
• Tolerance — Capacitance tolerance of −20% to +20% (±20%).
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronics — Suitable as a compact electrolytic for board-level circuits requiring a small bi-polar capacitor.
• Polarity-reversing or AC-capable circuits — Bi-polar construction and endurance testing with polarity inversion make it appropriate where polarity may change over time.
• Temperature-challenged systems — Use in equipment that operates across a wide temperature span, from −55 °C up to +105 °C.

Unique Advantages

• Bi-polar capability — Enables use in circuits where polarity can reverse without requiring specialized handling compared to single-polar capacitors.
• Wide operating range — −55 °C to +105 °C rating supports deployment in a broad set of environmental conditions.
• Long-term thermal endurance — 1000-hour rating at 105 °C provides a defined reliability baseline for high-temperature applications.
• Compact radial form factor — Small L×D dimensions and 2 mm lead spacing help to conserve board space while retaining through-hole mounting simplicity.
• Measured ripple performance — Specified ripple current values at 120 Hz and 10 kHz help with budgeting thermal and ripple-handling requirements in design.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
