UEP1E101MPD

The UEP1E101MPD is a Nichicon UEP series aluminum electrolytic capacitor designed as a bi-polarized, radial-lead solution for general-purpose electronic circuits. It provides 100 µF capacitance at a 25 V rating in a compact radial can package with 3.5 mm lead spacing.

Engineered for reliability across a wide operating temperature range, this part addresses circuits that require stable performance from -55 °C to 105 °C while offering measured ripple-current capability and RoHS compliance.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance, suitable for a range of general-purpose decoupling and coupling tasks.
• Bi-Polarized Construction — Designed for bipolar operation, enabling use in circuits where polarity reversal may occur.
• Wide Temperature Range — Specified for operation from -55 °C to 105 °C, supporting demanding thermal environments.
• Endurance at Elevated Temperature — Rated for 1000 hours at 105 °C, with endurance verification defined by the series specification.
• Ripple Current Performance — Rated ripple current of 110 mA at 120 Hz and 165 mA at 10 kHz, with frequency coefficients defined by the series datasheet.
• Low Leakage Current (Series Spec) — Series-level leakage specification: after 5 minutes at rated voltage and 20 °C, leakage current is not more than 0.03CV (µA), providing predictable standby behavior.
• Radial Lead Package — Radial, can-style package with 3.5 mm lead spacing and radial lead mounting for through-hole PCB assembly.
• RoHS Compliant — Conforms to RoHS directive requirements for material compliance.

Typical Applications

• Industrial Controls — Engineered for extended-temperature operation, suitable for control electronics and instrumentation deployed in wide-ranging thermal conditions.
• General-Purpose Power — Useful for decoupling and filtering in power rails and small power-supply circuits that require a bipolar electrolytic capacitor.
• Consumer and Electronic Equipment — Appropriate for general-purpose circuit boards and assemblies where a compact, radial bi-polar capacitor is required.

Unique Advantages

• Bi-polar design for polarity-flexible circuits — Eliminates polarity constraints where signal or charge reversal can occur, simplifying design choices for AC- or bipolar-capacitor use cases.
• Wide operating temperature span — -55 °C to 105 °C rating supports deployment across harsh and variable environments without loss of specified performance.
• Documented endurance at high temperature — 1000-hour rating at 105 °C offers predictable long-term behavior for designs with elevated thermal stress.
• Quantified ripple specifications — Specified ripple current values at 120 Hz and 10 kHz enable targeted thermal and ripple budgeting in power designs.
• Through-hole radial package — Radial lead can construction with 3.5 mm lead spacing simplifies handling and insertion for manual or automated through-hole assembly.
• Regulatory compliance — RoHS compliance supports material-restricted BOM requirements.
