UUN1V101MNQ1MS

The UUN1V101MNQ1MS is a 100 µF, 35 V bi‑polar aluminum electrolytic chip capacitor from Nichicon’s UUN series designed for surface mounting on high‑density PCBs. Its chip‑type, bi‑polar construction and RoHS compliance make it suitable for general‑purpose electronics where compact bipolar capacitance and reliable performance across a wide temperature range are required.

Engineered for automated assembly, this SMD radial can offers a combination of capacitance, ripple handling and thermal endurance for applications that require stable behavior from −55 °C to +105 °C.

Key Features

• Bi‑Polar Construction Bi‑polarized design supports applications where polarity may be reversed during operation and enables symmetric performance across positive and negative voltages.
• Capacitance & Voltage 100 µF nominal capacitance at a 35 V rated voltage with ±20% tolerance for general‑purpose decoupling and energy storage.
• Surface‑Mount, Chip Type Chip‑type radial can packaged for surface mounting on high‑density PC boards and compatible with automatic mounting machines fed with carrier tape.
• Wide Operating Temperature Specified for −55 °C to +105 °C, suitable for designs requiring extended temperature range operation.
• Ripple Current Capability Rated ripple current of 180 mA at 120 Hz and 270 mA at 10 kHz (part data), supporting AC or high‑frequency ripple conditions.
• Endurance & Reliability Endurance specified as 2000 hours at 105 °C (with polarity inversion in endurance testing), ensuring predictable long‑term performance under elevated temperature stress.
• Low Leakage Leakage current guaranteed not more than 0.03CV (µA) after 1 minute’s application of rated voltage at 20 °C, enabling low‑leak designs.
• RoHS Compliant Meets relevant RoHS directives (2011/65/EU, (EU)2015/863).
• Board Footprint Compact dimensions (L: 1.35 × D: 1.25 cm) with recommended land size L: 1.28 × W: 1.28 cm to aid PCB layout for dense assemblies.

Typical Applications

• General‑Purpose Electronic Modules Bulk and decoupling capacitance for mixed‑signal boards and power rails where bipolar performance is required.
• High‑Density PCB Assemblies Chip‑type SMD packaging fits space‑constrained layouts and automated assembly workflows fed with carrier tape.
• AC‑Coupled or Polarity‑Reversal Circuits Bi‑polarized construction supports circuits that experience voltage reversal or require symmetric capacitance behavior.
• Thermally Demanding Designs Applications requiring stable operation across −55 °C to +105 °C and defined endurance at elevated temperature.

Unique Advantages

• Bi‑Polar Performance: Allows use where polarity inversion or AC operation occurs without the constraints of polarized electrolytics.
• Compact, PCB‑Friendly Form Factor: Chip‑type radial can and defined land pattern simplify PCB layout in space‑limited designs and support automated placement.
• Measurable Ripple Handling: Specified ripple currents at 120 Hz and 10 kHz provide clear design targets for thermal and ripple budgeting.
• Long‑Term Thermal Endurance: 2000‑hour rating at 105 °C gives predictable aging characteristics for elevated‑temperature applications.
• Low Leakage Baseline: 0.03CV (µA) leakage specification after voltage application helps maintain low standby currents in sensitive circuits.
• Regulatory Compliance: RoHS conformity supports deployment in regulated markets without additional material restrictions.
