ULR2D120MNL1GS

The ULR2D120MNL1GS is a chip‑type, high‑voltage aluminum electrolytic capacitor in a compact surface‑mount can. It delivers a 12 µF nominal capacitance at a 200 V rating with ±20% tolerance (measured at 120 Hz, 20°C), and is part of Nichicon's ULR series designed for demanding high‑voltage SMD applications.

With AEC‑Q200 qualification, a −40°C to +105°C operating range, and a 3000‑hour endurance rating at 105°C, this part is positioned for automotive and other high‑reliability power electronics where compact, high‑voltage SMD capacitance is required.

Key Features

• High‑voltage chip type — Rated voltage 200 V with a nominal capacitance of 12 µF and ±20% tolerance at 120 Hz, 20°C.
• Compact SMD package — Chip can package, case size φ8×10 mm (L: 1.0 cm × D: 0.8 cm) suited for space‑constrained board layouts; recommended land size 8.3 × 8.3 mm.
• Automotive‑grade qualification — AEC‑Q200 rated for use in automotive applications requiring component qualification to that standard.
• Wide temperature range — Specified for operation from −40°C to +105°C to support elevated ambient environments.
• Endurance and reliability — Meets endurance specification after 3000 hours at 105°C with limits on capacitance change, tan δ and leakage current as defined by the series.
• Electrical loss and leakage — Tangent of loss angle (tan δ) ≤ 0.20 (120 Hz, 20°C) and specified leakage current of 196 µA at 20°C after 1 minute.
• Ripple performance — Rated ripple current 50 mA at 120 Hz and 80 mA at 10 kHz; frequency coefficients available (e.g., 1.00 at 120 Hz, 1.60 at ≥10 kHz) to scale allowable ripple with frequency.

Typical Applications

• Automotive power electronics — Suited for high‑voltage SMD capacitor requirements in automotive subsystems where AEC‑Q200 qualification is required.
• High‑voltage DC link and filtering — Compact chip form factor for smoothing and filtering in high‑voltage SMD power stages.
• Control and power modules — Designed for board‑level use in compact power control modules operating across −40°C to +105°C.

Unique Advantages

• AEC‑Q200 qualified for automotive use: Provides a qualification level aligned with automotive design needs, aiding component selection for vehicle electronics.
• High‑voltage capability in a small SMD can: 200 V rating and φ8×10 mm footprint deliver high voltage handling in a compact package to save PCB area.
• Long endurance at elevated temperature: 3000 hours at 105°C supports long‑life applications and predictable aging behavior.
• Defined electrical performance: Low tan δ (≤0.20) and specified leakage current (196 µA after 1 minute at 20°C) allow straightforward electrical budgeting in designs.
• Ripple scalability across frequency: Published ripple current values and frequency coefficients make it easier to size the part for varying switching frequencies.
