UEP2A3R3MED

The UEP2A3R3MED is a Nichicon UEP series bi‑polar aluminum electrolytic capacitor designed for general‑purpose applications that require bipolar operation across a wide temperature range. This radial‑lead, can‑style capacitor offers 3.3 µF capacitance at a 100 V rating and is RoHS compliant.

Key mechanical and lifecycle details include a compact φ6.3 × 11 mm size, 2.5 mm lead spacing (±0.5 mm), bulk bag packaging, and an endurance rating of 1000 hours at 105°C with polarity inversion every 250 hours. Status: End Of Life.

Key Features

• Bi‑Polarized construction — Allows AC or inverted polarity operation per endurance test conditions, useful where polarity reversals occur.
• Wide operating temperature — Rated for −55°C to +105°C to support designs exposed to broad thermal environments.
• Voltage and capacitance — 3.3 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Low dissipation factor — tanδ maximum 0.10 measured at 20°C and 120 Hz, supporting predictable AC performance.
• Ripple handling — Specified low‑frequency ripple current of 25 mA at 120 Hz and high‑frequency ripple current of 50 mA at 10 kHz for AC/filtered applications.
• Leakage current — Specified leakage current of 9.9 µA, supporting low‑leakage requirements in standby or filter circuits.
• Radial lead package — φ6.3 × 11 mm can with 2.5 mm lead spacing for through‑hole mounting and simple PCB placement.
• Compliance and packaging — RoHS compliant and supplied in bulk (no terminal forming) / bag packing.

Typical Applications

• AC coupling and signal path components — Bi‑polar construction enables capacitor use in circuits that experience polarity reversal or AC bias.
• General power filtering — 100 V rating and defined ripple currents suit decoupling and filtering in moderate‑voltage power supplies and control electronics.
• Industrial and instrumentation electronics — Wide −55°C to +105°C temperature range supports equipment operating across broad thermal conditions.

Unique Advantages

• Bi‑polar capability: Simplifies designs that require AC or alternating polarity operation without additional balancing components.
• Wide temperature tolerance: −55°C to +105°C specification helps maintain performance in thermally challenging environments.
• Measured dissipation and ripple specs: tanδ (0.10 at 20°C, 120 Hz) and frequency‑rated ripple currents (25 mA @120 Hz, 50 mA @10 kHz) enable predictable AC behavior in filter and coupling roles.
• Compact radial package: φ6.3 × 11 mm can and 2.5 mm lead spacing provide a small footprint for through‑hole layouts.
• Defined endurance: 1000 hours at 105°C with polarity inversion every 250 hours gives a clear reference for life‑cycle planning and thermal stress expectations.
• RoHS compliant: Meets RoHS requirements for environmental regulatory conformity where applicable.
