Overview of ULR2W3R9MNL1GS – 3.9 µF, 450 V Surface-Mount Aluminum Electrolytic Capacitor

The ULR2W3R9MNL1GS is a chip-type, high-voltage aluminum electrolytic capacitor from Nichicon's ULR series designed for surface-mount applications. It delivers 3.9 µF capacitance at a 450 V rating in a compact φ8 × 10 mm can-style SMD package and is offered in embossed carrier taping for automated assembly.

Targeted for automotive and other high-voltage board-level designs, the part combines high-voltage capability, defined endurance at elevated temperature, and AEC-Q200 qualification for use in demanding environments.

Key Features

  • Capacitance & Tolerance — 3.9 µF nominal capacitance with ±20% tolerance at 120 Hz, 20°C.
  • High Voltage Rating — Rated for 450 V operation, part of the ULR high-voltage chip family.
  • Loss Characteristics — Tangent of loss angle (tan δ) specified at 0.30 (measurement condition: 20°C, 120 Hz for 450 V).
  • Ripple Current Performance — Low-frequency ripple current 25 mA at 120 Hz and high-frequency ripple current 40 mA at 10 kHz; frequency coefficient data is available for scaling across frequencies.
  • Leakage Current — Specified leakage current of 170.2 µA (measured per datasheet conditions: after 1 minute at rated voltage, 20°C formula available in datasheet).
  • Endurance & Temperature Range — Rated life of 3000 hours at 105°C; operating temperature range −40°C to +105°C.
  • Package & Footprint — Chip-type radial can SMD, size φ8 × 10 mm; recommended land pattern 8.3 × 8.3 mm; supplied in embossed carrier taping for pick-and-place.
  • Automotive-Grade Qualification — AEC-Q200 rated for applications requiring automotive stress test qualification.

Typical Applications

  • Automotive Electronics — AEC-Q200 qualification and 450 V rating suit vehicle electronic modules that require high-voltage SMD capacitors.
  • High-Voltage SMD Designs — Compact chip form factor (φ8 × 10 mm) provides 3.9 µF at 450 V for board-level high-voltage assemblies.
  • Temperature-Intensive Environments — 3000-hour endurance at 105°C and −40°C to +105°C operating range address sustained elevated-temperature operation.

Unique Advantages

  • Compact high-voltage solution: Delivers 3.9 µF at a 450 V rating in a φ8 × 10 mm SMD can, enabling space-efficient high-voltage designs.
  • Automotive-ready qualification: AEC-Q200 rating supports use in automotive electronic systems where component-level stress qualification is required.
  • Defined endurance at elevated temperature: 3000 hours at 105°C provides predictable lifetime behavior for thermal design planning.
  • Clear ripple and loss specifications: Published ripple current ratings (25 mA @120 Hz, 40 mA @10 kHz) and tan δ allow straightforward integration into power and filtering applications.
  • SMD assembly-friendly packaging: Embossed carrier taping with a recommended land pattern (8.3 × 8.3 mm) facilitates automated placement and consistent yields.
