UEP1A102MHD

The UEP1A102MHD is a bi‑polarized aluminum electrolytic capacitor from Nichicon's UEP series, rated 10 V with a nominal capacitance of 1000 µF and ±20% tolerance. It is a radial‑lead, can‑style capacitor designed for general‑purpose electronic assemblies that require wide temperature operation and robust endurance.

Key attributes include a wide operating temperature range of −55 °C to +105 °C, a rated life of 1000 hours at 105 °C, and RoHS compliance—providing predictable performance for designs that must withstand elevated temperatures and polarity inversion during use.

Key Features

• Bi‑Polarized Construction Bi‑polarized design validated by endurance testing with polarity inverted every 250 hours; suitable where polarity reversal may occur.
• Wide Temperature Range Specified to operate from −55 °C to +105 °C, allowing deployment across harsh thermal environments.
• Capacitance and Voltage 1000 µF nominal capacitance at a rated voltage of 10 V with ±20% tolerance for general‑purpose energy storage and decoupling.
• Endurance and Reliability Rated life of 1000 hours at 105 °C; after life test the capacitor meets specified limits for capacitance change, tan δ, and leakage current per the UEP series endurance criteria.
• Ripple Current Performance Rated ripple current: 510 mA at 120 Hz and 586.5 mA at 10 kHz (frequency‑dependent characteristics provided by the series specifications).
• Radial Lead Can Package Compact φ12.5 × 20 mm can (L: 2.0 cm × D: 1.25 cm) with 5 mm lead spacing (±0.5 mm) for through‑hole PCB mounting; available in bulk or bag packing.
• Low Leakage Specified leakage current listed at 300 µA, enabling stable long‑term performance after voltage application.
• Regulatory Compliance RoHS compliant, meeting environmental directives listed for the UEP series.

Typical Applications

• General Purpose Electronics Suitable for a wide range of general‑purpose circuits where a bi‑polarized electrolytic capacitor is required.
• Wide‑Temperature Systems Use in equipment exposed to extended temperature ranges, taking advantage of −55 °C to +105 °C operation and 1000‑hour high‑temperature endurance.
• Radial‑Lead PCB Designs Intended for through‑hole mounting where a compact, can‑style radial capacitor with 5 mm lead spacing is required.
• Bulk Production and Prototyping Available in bulk (no terminal forming) or bag packing, facilitating high‑volume assembly or prototype build workflows.

Unique Advantages

• Bi‑Polarized design for polarity inversion Endurance testing with polarity inversion demonstrates suitability where polarity may change during operation.
• Wide operational temperature window Rated from −55 °C to +105 °C, enabling use across diverse thermal environments without specification changes.
• Compact radial can form factor φ12.5 × 20 mm package and 5 mm lead spacing offer a space‑efficient through‑hole solution for board layouts.
• Defined high‑temperature lifetime 1000 hours at 105 °C gives a clear reliability expectation for thermal endurance planning.
• Frequency‑aware ripple capability Ripple current ratings provided for 120 Hz and 10 kHz help align capacitor selection with expected operating frequencies.
• RoHS compliant Conforms to RoHS directives as specified for the UEP series, supporting regulatory compliance goals.
