ULR2G120MNL1GS

The ULR2G120MNL1GS is a surface-mount aluminum electrolytic capacitor from Nichicon’s ULR series, configured as a high-voltage chip-type radial can in an SMD package. It provides 12 µF capacitance at a 400 V rating with polarized construction and engineered electrical characteristics for elevated-voltage applications.

Designed for demanding thermal and electrical environments, this part offers specified ripple current performance, controlled loss (tan δ), and extended endurance (3000 hours at 105°C), making it suitable for automotive and industrial high-voltage circuitry where predictable long-term behavior is required.

Key Features

• Capacitance & Voltage — 12 µF nominal capacitance with a tolerance of -20% to +20% and a rated voltage of 400 V.
• Low loss (tan δ) — tan δ specified at 0.25 (measured at 20°C, 120 Hz), enabling predictable dissipation characteristics in AC ripple conditions.
• Ripple current performance — Low-frequency ripple current 55 mA at 120 Hz and high-frequency ripple current 88 mA at 10 kHz, with series frequency coefficients published for design scaling.
• Leakage current — Specified leakage current of 292 µA, provided for accurate power-loss and hold-up calculations.
• Temperature and endurance — Operating range -40°C to +105°C with endurance rated at 3000 hours at 105°C under rated voltage.
• AEC-Q200 qualification — Series rating listed as AEC-Q200 for designs requiring component-level automotive qualification.
• Package & mounting — Radial can SMD (chip type) surface-mount package, size listed as φ10 × 13.5L with HeightSeatedMax 1.35 cm; supplied in embossed carrier taping for automated placement and in mass-production status.
• Polarized construction — Polar capacitor construction, suitable for DC high-voltage applications where polarity is controlled.
• Soldering heat resistance (series spec) — Series-level resistance to soldering heat per JIS criteria (hot plate 250°C for 30 s) is defined in the datasheet.

Typical Applications

• Automotive power electronics — AEC-Q200-qualified 400 V capability and extended temperature/endurance make it suitable for high-voltage smoothing and decoupling in automotive control modules.
• High-voltage power supplies — 400 V rating and characterized ripple/leakage figures support DC-link and smoothing functions in elevated-voltage supplies.
• Industrial control and instrumentation — Durable operation to 105°C and 3000-hour endurance are useful where continuous thermal and electrical stress is present.

Unique Advantages

• 400 V rated capacitance: Enables use on elevated-voltage rails without series stacking, simplifying board design.
• Specified loss angle (tan δ): Measured tan δ (0.25 at 20°C, 120 Hz) allows accurate dissipation and thermal planning.
• Documented ripple and leakage values: LF and HF ripple currents plus leakage current are provided for reliable margin calculations in power designs.
• High-temperature endurance: 3000 hours at 105°C gives designers a defined lifetime metric for long-term reliability assessments.
• AEC-Q200 rating: Series-level qualification supports selection for automotive-grade applications that require qualified components.
• Surface-mount radial can in compact footprint: φ10×13.5L SMD can and embossed carrier taping support automated assembly in space-constrained layouts.
