UEP2A4R7MED

The UEP2A4R7MED is a bi‑polarized aluminum electrolytic capacitor in a radial can package designed for general‑purpose electronic circuits. It delivers 4.7 µF at 100 V with a wide operating temperature range of −55 °C to +105 °C, making it suitable for designs that require polarity‑reversible operation and extended temperature tolerance.

Engineered for compact radial‑lead installations, this RoHS‑compliant component balances small footprint and verified endurance—1000 hours at 105 °C with polarity inversion—providing a reliable option for equipment that sees temperature extremes or alternating polarities.

Key Features

• Electrical Performance — 4.7 µF nominal capacitance with ±20% tolerance and rated voltage of 100 V for high‑voltage general‑purpose filtering and coupling tasks.
• Bi‑Polar Construction — Bi‑polarized design supports applications where polarity reversal can occur; endurance testing includes polarity inversion every 250 hours during a 1000‑hour 105 °C test.
• Wide Temperature Range — Operates from −55 °C to +105 °C, supporting designs exposed to broad environmental conditions.
• Ripple Current Capability — Specified ripple handling of 30 mA at 120 Hz and 60 mA at 10 kHz, enabling use across low and higher frequency ripple conditions.
• Leakage Current Specification — Leakage current limited per datasheet: after 5 minutes at rated voltage and 20 °C, I ≤ 0.03 × C × V (µA), providing predictable quiescent behavior.
• Compact Radial Can Package — Radial lead, can‑style package with 2.5 mm lead spacing and compact dimensions (L: 1.1 × D: 0.63 cm) for through‑hole PCB layouts.
• Environmental Compliance — RoHS compliant construction suitable for markets requiring lead‑free components.

Typical Applications

• Bipolar/AC‑Coupled Circuits — Suitable where polarity can reverse or AC coupling is required thanks to its bi‑polarized design and polarity‑inversion endurance testing.
• Power Supply Filtering — Compact radial can provides decoupling and ripple suppression at 100 V systems, with specified ripple current performance at 120 Hz and 10 kHz.
• Industrial and Instrumentation Electronics — Wide −55 °C to +105 °C operating range makes it appropriate for industrial sensors, control modules, and instrumentation exposed to varying temperatures.

Unique Advantages

• Polarity‑Reversal Ready: Bi‑polar construction and endurance testing with polarity inversion enable use in circuits subject to alternating or changing polarity.
• Wide Ambient Tolerance: Rated for −55 °C to +105 °C, reducing the need for additional thermal derating or specialized components in temperature‑challenging assemblies.
• Predictable Endurance: Lifetime characterized as 1000 hours at 105 °C (with polarity inversion every 250 hours), providing a clear, verifiable reliability baseline for design planning.
• Compact Through‑Hole Form Factor: Radial lead, can package with 2.5 mm lead spacing and small footprint simplifies layout for replacement or legacy PCB designs.
• Measured Ripple Ratings: Published ripple current values at 120 Hz and 10 kHz allow designers to match the capacitor to expected ripple environments without guesswork.
• RoHS Compliant: Lead‑free materials support regulatory requirements and simplify supply compliance management.
