UCK1V192MNJ1MS

The UCK1V192MNJ1MS is a chip‑type, low‑impedance aluminum electrolytic capacitor in a surface‑mount can package. It provides 1900 µF capacitance at a 35 V rating, with a broad operating temperature range from −55°C to +105°C and a rated life of 5000 hours at 105°C.

Engineered for automotive and other high‑reliability systems, this AEC‑Q200 qualified, RoHS‑compliant part combines high capacitance, low loss (tan δ 0.12 at 20°C/120 Hz) and practical surface‑mount packaging with embossed carrier taping for automated assembly.

Key Features

• Capacitance & Voltage — 1900 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in moderate‑voltage systems.
• Low Impedance / Low Loss — tan δ (DF) of 0.12 measured at 20°C and 120 Hz, delivering reduced AC loss suitable for high ripple environments.
• Ripple Current Capability — Rated ripple current of 955 mA at 120 Hz and 1.91 A at 10 kHz to support filtering and power conditioning tasks.
• High Temperature Endurance — Qualified for 5000 hours of operation at 105°C; specified endurance limits include capacitance change within ±30%, tan δ ≤ 200% of initial, and leakage current ≤ initial specified value after the test.
• Leakage Current & Polarized Design — Polarized construction with a measured leakage current figure of 665 µA; suitable where polarized electrolytic capacitance is required.
• Surface Mount Package & Tape Packaging — Radial can SMD package (φ16 × 16.5L) supplied on embossed carrier tape for compatibility with automated pick‑and‑place assembly.
• Automotive Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, supporting regulated and automotive development workflows.

Typical Applications

• Automotive Electronics — Designed for automotive electronic modules where AEC‑Q200 qualification, high temperature tolerance (up to 105°C) and long life (5000 h at 105°C) are required.
• Power Supply Filtering — Bulk smoothing and decoupling in 35 V power rails, leveraging 1900 µF capacitance and specified ripple current ratings.
• High‑Temperature Embedded Systems — Use in electronics operating across −55°C to +105°C that require stable capacitance and endurance under thermal stress.

Unique Advantages

• High Energy Density in SMD Form — 1900 µF in a φ16 × 16.5L surface‑mount can provides substantial bulk capacitance while supporting automated assembly.
• Designed for High‑Temperature Service — Rated for 5000 hours at 105°C, enabling extended field life in thermally demanding applications.
• Measured Low Loss for Improved Efficiency — Low tan δ (0.12 at 20°C/120 Hz) reduces dissipative losses in AC and ripple conditions.
• Automotive‑Grade Reliability — AEC‑Q200 qualification and RoHS compliance support design and regulatory needs for automotive systems.
• Production‑Ready Packaging — Embossed carrier taping and mass production status simplify supply chain and assembly integration.
