UEP1J4R7MED

The UEP1J4R7MED is a bi‑polarized aluminum electrolytic capacitor in a compact radial can package designed for general‑purpose AC and DC applications. It provides 4.7 µF capacitance at a 63 V rating with a wide operating temperature range from -55 °C to 105 °C, making it suitable for designs that require bipolar operation across wide thermal environments.

This radial lead component features a φ6.3 mm can with a 2.5 mm lead spacing and is specified for 1,000 hours of endurance at 105 °C with polarity inversion, offering predictable performance and service life for embedded and industrial electronics.

Key Features

• Electrical Ratings — 4.7 µF nominal capacitance with a 63 V rated voltage and tolerance of -20% to +20%.
• Bi‑Polarized Construction — Designed for bipolar operation (polarity can be inverted during endurance testing), enabling AC‑biased and coupling applications.
• Wide Temperature Range — Specified for operation from -55 °C to +105 °C to support designs exposed to broad thermal conditions.
• Endurance and Stability — Rated for 1,000 hours at 105 °C with polarity inverted every 250 hours; capacitance change limits and loss angle (tan δ) criteria are defined by the series specification.
• Ripple Current Performance — Specified ripple current: 31 mA at 120 Hz and 62 mA at 10 kHz, suitable for decoupling and filtering at low and high frequencies.
• Compact Radial Can Package — φ6.3 mm × 11 mm can (size dimension L: 1.1 cm × D: 0.63 cm), radial lead mounting with 2.5 mm lead spacing for through‑hole PCB layouts.
• Leakage and Loss Characteristics — Series leakage current specification is not more than 0.03CV (µA) after 5 minutes at 20 °C; tan δ maximum for the 63 V rating is 0.12 (per series data).
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• AC‑Coupling and Signal Conditioning — Use the bi‑polarized design for coupling stages and circuits that require AC bias handling without DC polarity constraints.
• Power Supply Decoupling — Compact radial package and defined ripple specs make it suitable for local decoupling on control and analog supply rails.
• Industrial Control Electronics — Wide operating temperature and 1,000‑hour endurance at 105 °C support control and instrumentation modules exposed to elevated temperatures.
• Communications and Measurement Equipment — Stable capacitance and well‑defined loss/impedance behavior across frequency help with filtering and signal stability in measurement and RF front‑end circuits.

Unique Advantages

• Bipolar operation capability: Enables AC‑biased and polarity‑reversing applications without the restrictions of polarized electrolytics.
• Wide temperature envelope: -55 °C to 105 °C operation supports deployments in environments with large thermal swings.
• Defined high‑temperature endurance: 1,000 hours at 105 °C with polarity inversion provides measurable lifetime behavior for reliability planning.
• Compact, through‑hole mounting: φ6.3 mm radial can with 2.5 mm lead spacing simplifies PCB layout for space‑constrained designs that prefer axial/radial components.
• Frequency‑aware ripple handling: Published ripple current values at 120 Hz and 10 kHz let you size the capacitor for both low‑ and high‑frequency decoupling needs.
• RoHS compliance: Meets environmental requirements for regulated applications.
