ULV2D180MNL1GS

The ULV2D180MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon's ULV series, designed for high-voltage, long-life surface-mount applications. It delivers 18 µF capacitance at a 200 V rating in a compact SMD can package suitable for automated placement.

Engineered for demanding environments, this part targets automotive and power-electronics designs that require sustained performance over extended high-temperature operation and compatibility with carrier-tape mounting.

Key Features

• Capacitance & Voltage — 18 µF nominal capacitance with a 200 V rated voltage, providing high-voltage energy storage in a compact chip form.
• Long Life Endurance — Load life specified at 10000 hours at +105°C; capacitance change and leakage are specified after this endurance test per the datasheet.
• Temperature Range — Operational from −40°C to +105°C for use across wide ambient conditions.
• Surface-Mount Chip Package — Chip-type, can-style SMD package (radial, can - SMD) designed for automatic mounting using carrier tape; compact footprint of approximately 10 mm × 10 mm.
• Polarized — Polar electrolytic construction for DC applications where polarity is defined.
• Ripple Current Capability — Rated for 65 mA at 120 Hz and 104 mA at 10 kHz to support filtering and decoupling in power circuits.
• Leakage Current (per datasheet) — Specified leakage current for 160–450 V parts: I ≤ 0.04CV + 100 µA (measured after 1 minute at 20°C), applicable to this 200 V part.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, reflecting suitability for automotive applications and lead-free directives.
• Tolerance — Capacitance tolerance of −20% to +20% (±20% standard measurement at 120 Hz, 20°C).

Typical Applications

• Automotive Power Modules — Filtering and decoupling in vehicle power-supply circuits where AEC-Q200 qualification and long life at elevated temperature are required.
• On-board Power Conversion — Bulk and smoothing capacitor for DC‑DC converters and power stages that need high-voltage, surface-mount capacitors with defined ripple capability.
• Embedded Power Filtering — Local energy storage and transient suppression in compact SMD assemblies for control units and power management boards.

Unique Advantages

• High-voltage in a compact SMD package: 200 V rating with a small 10 mm × 10 mm chip can saves board area while meeting higher-voltage requirements.
• Long-term high-temperature durability: 10000 hours at +105°C rated life provides predictable aging behavior for designs exposed to elevated operating temperatures.
• Automotive-grade qualification: AEC-Q200 qualification supports use in automotive electronic systems that require component-level reliability verification.
• Designed for automated assembly: Chip form factor and carrier-tape compatibility enable high-throughput surface-mount manufacturing.
• Measured ripple handling: Published ripple current ratings at 120 Hz and 10 kHz help designers validate thermal and performance margins in power circuits.
• Standards compliance: RoHS conformity aligns the part with environmental and materials directives.
