ULR2H3R9MNL1GS

The ULR2H3R9MNL1GS is a surface-mount, high-voltage aluminum electrolytic capacitor in Nichicon's ULR series. It provides 3.9 µF capacitance with a 500 V rated voltage in a compact chip-style can package designed for high-voltage applications.

Engineered for demanding temperature and endurance requirements, this part targets automotive and other high-voltage electronic systems that require stable capacitance, defined ripple handling, and long-term reliability under elevated temperature conditions.

Key Features

• Electrical Performance — Rated capacitance 3.9 µF with a tolerance of −20% to +20% and a rated voltage of 500 V, suitable for high-voltage circuit designs.
• Dielectric Loss (tan δ) — tanδ up to 0.30 measured at 20°C, 120 Hz and 500 V, enabling predictable dissipation characteristics in AC or ripple environments.
• Ripple Current Capability — Low-frequency ripple current 35 mA at 120 Hz and high-frequency ripple current 56 mA at 10 kHz, with frequency coefficients provided in the series datasheet for ripple scaling.
• Leakage Current — Typical leakage current listed as 178 µA; datasheet defines the leakage limit after 1 minute as not more than 0.04CV + 100 µA, providing clear design guidance.
• Reliability & Endurance — Rated lifetime 3000 hours at 105°C with endurance criteria (capacitance change, tanδ, leakage) specified when restored to 20°C after test.
• Temperature Range — Operating range from −40°C to +105°C for use across wide ambient conditions.
• Package & Mounting — Chip-type radial can SMD package (Size φ10×10L; SizeDimension L: 1 × D: 1 cm) supplied in embossed carrier taping for automated surface-mount assembly.
• AEC Rating — AEC-Q200 rated, indicating qualification for automotive electronic applications where that rating is required.

Typical Applications

• Automotive Electronics — Designed for high-voltage sections of automotive systems that demand long endurance and defined leakage/ripple behavior.
• Power-Supply Ripple Suppression — Provides defined low- and high-frequency ripple current handling for filtering and decoupling in high-voltage power rails.
• High-Voltage Modules — Suited to compact, board-mounted high-voltage modules where a small chip-style electrolytic capacitor is required.

Unique Advantages

• High Voltage Capability: 500 V rated voltage supports designs that require elevated DC bias handling without resorting to larger discrete solutions.
• Compact SMD Can Package: Chip-type φ10×10L packaging with embossed carrier taping enables space-efficient placement and automated assembly workflows.
• Defined Endurance: 3000 hours at 105°C provides predictable lifetime behavior for thermal-stressed applications and simplifies lifecycle planning.
• Measured Ripple and Loss Data: Published ripple currents (35 mA at 120 Hz, 56 mA at 10 kHz) and tanδ (0.30 at 500 V, 120 Hz, 20°C) let engineers size components precisely for AC and ripple conditions.
• AEC-Q200 Rated: Meets an established automotive component qualification standard included in the product specifications for designs targeting automotive systems.
