UUN1E102MNQ1MS

The UUN1E102MNQ1MS is a chip‑type aluminum electrolytic capacitor offering 1 mF (1000 µF) capacitance at a 25 V rating in a bi‑polar construction. It is designed for surface mounting on high‑density PC boards and for use in general‑purpose electronic circuits.

Key value propositions include bi‑polar operation across a wide temperature range (−55 °C to +105 °C), compatibility with automated tape‑fed mounting, and a design optimized for higher capacitance in larger φ12.5–φ18 case sizes.

Key Features

• Capacitance & Voltage — 1 mF (1000 µF) nominal capacitance with a 25 V rated voltage and ±20% tolerance for predictable filtering and energy storage.
• Bi‑Polar Construction — Bi‑polarized design suitable for circuits that require non‑polar behavior across the specified temperature range.
• Wide Operating Temperature — Rated for −55 °C to +105 °C to support designs exposed to broad thermal environments.
• Surface‑Mount Chip Type — Chip‑type, radial can SMD package engineered for high‑density PCBs and automatic mounting machines using carrier tape.
• Endurance — Life rating of 2000 hours at 105 °C with polarity inversion test conditions specified in the series datasheet.
• Ripple Current Performance — Rated ripple current of 780 mA at 120 Hz and 897 mA at 10 kHz, with frequency coefficients defined for ripple scaling.
• RoHS Compliance — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Compact Dimensions — Component size L: 2.15 × D: 1.8 cm with recommended surface‑mount land size of 1.83 × 1.83 cm for PCB layout.

Typical Applications

• High‑density surface‑mount PCBs — Designed for placement on tightly populated boards where chip‑type SMD packaging is required.
• Automated assembly lines — Compatible with carrier‑tape feed for automatic mounting machines, simplifying high‑volume production.
• General‑purpose electronic circuits — Provides bulk capacitance and ripple handling for a wide range of general‑purpose applications operating between −55 °C and +105 °C.

Unique Advantages

• High capacitance in chip form — Delivers 1 mF in a chip‑type SMD package, enabling substantial energy storage without requiring through‑hole mounting.
• Bi‑polar operation — Eliminates polarity constraints found in single‑polar electrolytics, expanding usable circuit topologies.
• Production friendly — Carrier‑tape compatibility and SMD packaging speed up placement and reduce assembly handling.
• Wide thermal range and proven endurance — Rated −55 °C to +105 °C with a 2000‑hour life at 105 °C to support designs requiring robust thermal performance.
• Measurable ripple capability — Specified ripple currents at 120 Hz and 10 kHz allow designers to size capacitors for expected operating conditions.
• Regulatory compliance — RoHS compliance supports environmentally constrained bill‑of‑materials requirements.
