UEP1H4R7MDD

The UEP1H4R7MDD is a bi‑polarized aluminum electrolytic capacitor in a radial can package designed for general-purpose electronic circuits. It combines a 4.7 µF capacitance with a 50 V rating and a compact footprint for use where a stable, bi‑polar capacitor is required.

Key value points include a wide operating temperature range of −55 °C to +105 °C, defined endurance at elevated temperature, and RoHS compliance, providing predictable performance across a range of environmental conditions.

Key Features

• Bi‑Polarized construction Designed as a bi‑polarized series for operation over a wide temperature range (−55 °C to +105 °C).
• Capacitance & tolerance 4.7 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20 °C).
• Rated voltage 50 V rated voltage suitable for general‑purpose circuit requirements.
• Endurance specification Rated for 1000 hours at 105 °C with the rated voltage applied and polarity inverted every 250 hours; capacitance change and electrical parameters meet the specified endurance limits.
• Ripple current performance 22 mA at 120 Hz and 44 mA at 10 kHz (rated ripple current values provided for design verification).
• Leakage and dissipation Leakage current specified as ≤ 0.03 × C × V (μA) after 5 minutes at 20 °C; tan δ (loss tangent) for 50 V models is specified (maximum 0.14 at 120 Hz, 20 °C).
• Package & mounting Radial lead, can style with 2 mm lead spacing; compact dimensions L: 1.1 cm × D: 0.5 cm for space‑constrained PCB layouts.
• Environmental compliance RoHS compliant (meets RoHS directive requirements).
• Identification Marked with white lettering on a black sleeve for clear part identification.

Typical Applications

• General‑purpose electronic circuits — Suitable where a bi‑polarized aluminum electrolytic capacitor is required for general circuit functions.
• Circuits subject to polarity reversals — Bi‑polar design and endurance testing with polarity inversion support use in sections where polarity may change over time.
• Compact PCB designs — Small radial can footprint and 2 mm lead spacing make it suitable for dense board layouts and tight component placement.

Unique Advantages

• Wide temperature capability: −55 °C to +105 °C rating supports reliable operation across broad environmental ranges.
• Polarization flexibility: Bi‑polar construction and endurance testing with periodic polarity inversion provide predictable behavior where polarity can reverse.
• Predictable longevity: Endurance defined as 1000 hours at 105 °C with specific limits on capacitance change, tan δ, and leakage current for design assurance.
• Compact radial package: 1.1 × 0.5 cm size and 2 mm lead spacing reduce board area while preserving through‑hole mounting simplicity.
• Specified ripple handling: Published ripple current values at 120 Hz and 10 kHz enable accurate thermal and ripple budgeting in power and signal designs.
• RoHS compliant: Meets environmental requirements for restricted substances.
