Overview of UCM1E392MNS1MS – Aluminum Electrolytic Chip, Low Impedance, 3900 µF, 25 V

The UCM1E392MNS1MS is a chip-type aluminum electrolytic capacitor designed for surface-mount assembly with low impedance characteristics. It delivers 3.9 mF capacitance at 25 V in a compact φ16 × 21.5 mm can, packaged for automatic placement via embossed carrier taping.

Engineered for demanding environments, this part offers high ripple-current capability, a wide operating temperature range from −55 °C to 105 °C, long endurance (5000 hours at 105 °C), and AEC-Q200 qualification for automotive applications.

Key Features

  • Capacitance & Voltage — 3.9 mF (3900 µF) rated at 25 V with ±20% tolerance, providing bulk energy storage for power rails.
  • Low Impedance Construction — Chip-type, low-impedance design with measured tanδ (DF) of 0.18 at 20 °C, 120 Hz, optimized for stable AC performance.
  • High Ripple Current Capability — Low-frequency ripple current 1.27 A (120 Hz) and high-frequency ripple current 2.54 A (10 kHz) to support dynamic load conditions.
  • Leakage Current — Specified leakage current of 975 µA, measured under rated conditions.
  • Endurance & Temperature Range — Rated for 5000 hours at 105 °C and an operating range of −55 °C to 105 °C to support extended life in elevated temperatures.
  • Package & Mounting — Surface-mount radial can (φ16 × 21.5 mm) with embossed carrier taping for automated PCB assembly; vibration resistant for mechanically demanding environments.
  • Standards & Compliance — AEC-Q200 rated and RoHS-compliant for regulated application environments.
  • Production Status — Mass production availability for volume designs and supply continuity.

Typical Applications

  • Automotive — Power rail smoothing: Bulk capacitance and low impedance support stabilization of 25 V power rails where capacitance and ripple handling are required.
  • Automotive — High-temperature modules: Rated for 5000 hours at 105 °C and operating from −55 °C to 105 °C for use in elevated-temperature automotive environments.
  • Automotive — High ripple-current circuits: Designed to handle both low-frequency (1.27 A at 120 Hz) and high-frequency (2.54 A at 10 kHz) ripple currents found in power electronics.

Unique Advantages

  • High bulk capacitance in a compact SMD can: 3.9 mF in a φ16 × 21.5 mm package reduces board area compared with discrete solutions requiring multiple parts.
  • Low-impedance performance: Specified tanδ of 0.18 (20 °C, 120 Hz) supports improved AC performance and stability in filtering and smoothing applications.
  • Robust ripple handling: Separate low- and high-frequency ripple ratings (1.27 A / 2.54 A) allow designers to size the capacitor to expected noise and load conditions.
  • Long-term high-temperature endurance: 5000 hours at 105 °C helps ensure long service life in sustained high-temperature deployments.
  • Automotive-grade compliance: AEC-Q200 rating and RoHS compliance simplify qualification for regulated automotive programs.
  • Assembly-ready packaging: Embossed carrier taping and SMD can format enable automated placement and consistent throughput in volume manufacturing.
