UBH1V181MNS1GS

The UBH1V181MNS1GS is a chip‑type aluminum electrolytic capacitor rated at 180 µF and 35 V, designed for surface‑mount applications that require high temperature tolerance and vibration resistance. It combines low temperature ESR characteristics with extended load‑life capability to support power filtering and decoupling in demanding environments.

Key use cases include automotive and industrial electronics and other embedded systems that operate across a wide temperature range. The part is AEC‑Q200 qualified and RoHS compliant, and is specified for sustained operation up to +150°C with a rated endurance appropriate for long‑life high‑temperature deployments.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 35 V rated voltage and ±20% tolerance, suitable for bulk storage and decoupling at moderate voltage rails.
• High Temperature Endurance — Specified operating range of −40°C to +150°C and a rated load life of 2000 hours at +150°C for the 10×10 mm case.
• Low ESR — Equivalent series resistance of 0.15 Ω (150 mΩ) measured at 100 kHz (20°C), delivering lower loss and improved ripple handling.
• Low‑Temperature Stability — Impedance stability characterized down to −40°C with a maximum Z(−40°C)/Z(+20°C) ratio of 4 at the 35 V rating.
• Ripple Current Capability — Rated ripple current of approximately 120 mA at high frequency (10 kHz) and about 80.4 mA at low frequency (120 Hz), per the product specification.
• Package & Mounting — Chip‑type radial can in a 10 × 10 mm case (L × D) designed for surface‑mount assembly; recommended land size 10.3 × 10.3 mm.
• Reliability & Compliance — AEC‑Q200 qualification for demanding applications and RoHS compliance for environmental regulation adherence.
• Polarized Construction — Standard polarized aluminum electrolytic design for traditional DC filtering topologies.

Typical Applications

• Automotive Electronics — Engine control units, power modules and other vehicle systems that require AEC‑Q200 qualification and sustained performance at elevated temperatures.
• Power Conversion — Input/output filtering and energy buffering in DC–DC converters and power supplies operating in high‑temperature environments.
• Industrial Controls — Motor drives, PLCs and control electronics exposed to vibration and extended thermal stress.
• Embedded Systems for Harsh Environments — Electronics deployed in elevated ambient temperature conditions where low ESR and long load life are required.

Unique Advantages

• Proven high‑temperature endurance: Rated for 2000 hours at +150°C (10×10 mm), providing predictable life in continuous high‑temperature applications.
• Low‑loss performance: 0.15 Ω ESR at 100 kHz reduces dissipation and improves ripple handling for high‑frequency power rails.
• Low‑temperature reliability: Defined impedance ratio to −40°C ensures functional filtering across the specified industrial temperature range.
• Automotive‑grade qualification: AEC‑Q200 qualification supports use in vehicle electronics where supplier qualification is required.
• Compact SMD package: 10 × 10 mm chip‑type can and defined land pattern simplify board layout for tight designs while maintaining robustness to vibration.
