UEP1A330MDD

The UEP1A330MDD is a bi-polarized aluminum electrolytic capacitor from Nichicon's UEP series, configured in a radial‑lead can. It provides 33 µF capacitance at a 10 V rating with ±20% tolerance and is intended for general‑purpose electronic applications.

Designed for extended temperature operation and industrial environments, this part supports a wide operating range from −55 °C to +105 °C, meets RoHS requirements, and delivers endurance defined by the series (1000 hours at 105 °C with polarity inversion every 250 hours).

Key Features

• Bi‑Polarized Design Enables operation with alternating polarity where a bipolar electrolytic capacitor is required.
• Wide Temperature Range Rated for operation from −55 °C to +105 °C to support temperature‑sensitive designs.
• Capacitance and Voltage 33 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance.
• Endurance and Reliability Specified endurance of 1000 hours at 105 °C with polarity inverted every 250 hours as per the UEP series specification.
• Low Leakage Characteristic Leakage current (after 5 minutes at rated voltage, 20 °C) is specified as not more than 0.03 × C × V (µA) for the series.
• Dissipation Factor (tan δ) Series specification shows a tan δ maximum of 0.24 at 10 V (measured at 120 Hz, 20 °C).
• Ripple Current and Frequency Response Rated ripple current is 45 mA at 120 Hz and 90 mA at 10 kHz for this part; series frequency coefficients (for 10–47 µF) permit higher ripple at higher frequencies (e.g., 1.35× at 300 Hz, 2.00× at ≥10 kHz relative to 120 Hz).
• Package and Mounting Radial lead, can style package with 2 mm lead spacing and compact footprint (L: 1.1 × D: 0.5 cm).
• Environmental Compliance Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics — Suited for circuits requiring a bi‑polar electrolytic capacitor for board‑level implementations.
• AC Coupling and Signal Conditioning — Bipolar construction supports alternating polarity requirements in coupling and filtering tasks.
• Temperature‑Critical Systems — Wide −55 °C to +105 °C operating range makes it suitable where broad environmental performance is needed.
• Compact Board Designs — Radial lead can and small footprint accommodate space‑constrained PCB layouts.

Unique Advantages

• Bipolar capability: Eliminates the need for paired polarized caps in some AC or alternating‑polarity applications, simplifying BOM and layout.
• Wide operating temperature: −55 °C to +105 °C rating ensures predictable behavior across a broad environmental range.
• Quantified endurance: 1000 hours at 105 °C with polarity inversion every 250 hours provides a defined reliability metric for high‑temperature designs.
• Measured leakage spec: Series leakage current limit (≤0.03CV μA after 5 minutes at 20 °C) helps designers estimate standby and quiescent currents.
• High‑frequency ripple handling: Specified ripple currents (45 mA at 120 Hz, 90 mA at 10 kHz) and series frequency coefficients allow predictable ripple performance across frequency.
• Regulatory compliance: RoHS conformity supports environmental and regulatory requirements for modern electronics manufacturing.

Why Choose UEP1A330MDD?

The UEP1A330MDD is positioned for engineers who need a compact, bi‑polar aluminum electrolytic capacitor that performs across a wide temperature span and delivers series‑specified endurance and leakage characteristics. Its radial‑lead can package and clearly defined ripple and frequency behavior make it straightforward to specify into board‑level designs where alternating polarity or wide environmental range is required.

Manufactured by Nichicon and conforming to RoHS, this part is suitable for procurement into general‑purpose and temperature‑sensitive electronic products where long‑term performance and predictable electrical characteristics are important.
