UCX1V182MNS1MS

The UCX1V182MNS1MS is a chip‑type aluminum electrolytic capacitor engineered for high‑temperature operation up to 135°C. It is a polarized, surface‑mount radial can designed for automatic mounting machines fed with carrier tape and targeted at demanding power and electronics systems in harsh environments.

This part combines 1.8 mF capacitance with a 35 V rating, AEC‑Q200 qualification and explicit ESR characterization after low‑temperature testing, offering designers predictable filtering and decoupling performance across −40°C to +135°C.

Key Features

• Capacitance & Voltage – 1.8 mF capacitance at a rated voltage of 35 V with a tolerance of −20% to +20% for predictable energy storage and decoupling.
• High‑Temperature Endurance – Rated for operation from −40°C to +135°C with a specified lifetime of 2000 hours at 135°C.
• Low‑Temperature ESR Characterization – ESR specification added after testing at −40°C; nominal ESR is 35 mΩ measured at 100 kHz for reliable high‑frequency performance.
• Ripple Current Capability – Supports 1.1 A at 120 Hz and 2.2 A at 10 kHz to handle ripple and transient currents in power stages.
• Automotive‑Grade Reliability – AEC‑Q200 qualified and RoHS compliant, suitable for designs that demand recognized reliability standards.
• Surface Mount, Carrier‑Tape Compatible – Radial can SMD package designed for automatic mounting machines; compact physical footprint (L: 2.15 × D: 1.8 cm) with recommended land size L: 1.83 × W: 1.83 cm.
• Polarized Electrolytic Construction – Standard polarized aluminum electrolytic behavior for bulk energy storage and smoothing applications.

Typical Applications

• Automotive Power Electronics – Bulk filtering and smoothing in control modules and power converters, leveraging AEC‑Q200 qualification and high‑temperature endurance.
• Power Supply Filtering – DC bus and output filtering where high ripple current capability and low ESR at high frequency improve voltage stability.
• Harsh‑Environment Embedded Systems – Energy storage and decoupling for electronics operating across −40°C to +135°C.

Unique Advantages

• High‑temperature reliability: 2000 hours endurance at 135°C enables sustained performance in elevated temperature environments.
• Measured ESR at low temperature: ESR specified after −40°C testing and rated at 35 mΩ (100 kHz), providing confidence in high‑frequency behavior across the full temperature range.
• Automated assembly ready: Carrier‑tape compatibility and SMD radial‑can package streamline pick‑and‑place integration for volume production.
• Designed for ripple and transients: Specified ripple currents of 1.1 A (120 Hz) and 2.2 A (10 kHz) support demanding power stages and converters.
• Industry qualification: AEC‑Q200 qualification and RoHS compliance align the component with regulated and automotive projects.
• Compact footprint: Small L × D size (2.15 × 1.8 cm) and defined land pattern support space‑constrained board layouts.
