UPM1H122MHD

The UPM1H122MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series. It delivers 1200 µF capacitance at a 50 V rating in a low-impedance, high-reliability radial can package (φ16 × 35.5 mm).

Designed for demanding environments, this part targets automotive and other high-reliability power applications by combining high ripple-current capability, extended load-life endurance, and AEC-Q200 qualification.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 50 V for bulk energy storage and smoothing.
• Low Impedance — Typical impedance of 28 mΩ to reduce voltage ripple and improve power stability.
• High Ripple Current — Low-frequency ripple current 1.673 A (120 Hz) and high-frequency ripple current 2.04 A (200 kHz) to handle demanding power-supply conditions.
• High Temperature Endurance — Rated for 5000 hours at 105°C, providing long-term stability under elevated temperature and bias.
• AEC-Q200 Qualified — Meets AEC-Q200 requirements for use in automotive electronics (as specified in product data).
• Radial Lead Package — Can-style radial package with φ16×35.5 mm dimensions and 7.5 mm lead spacing (±0.5 mm), available in bulk/bag packing.
• Operating Range — Specified for −55°C to +105°C operation for broad environmental tolerance.
• Electrical Characteristics — Capacitance tolerance ±20%, tan δ 0.1 (measured at 20°C, 120 Hz), and leakage current 1800 µA.
• RoHS Compliant — Conforms to RoHS requirements as listed in the product data.

Typical Applications

• Automotive power systems — Bulk filtering and energy buffering in automotive power-supply circuits, leveraging the 50 V rating, high ripple capability, and AEC-Q200 qualification.
• Automotive ECUs and controllers — Smoothing and decoupling for electronic control units operating across −55°C to +105°C and requiring long endurance at high temperature.
• Power modules and converters — Bulk capacitance and ripple handling for DC–DC converters and power conditioning circuits in harsh environments.

Unique Advantages

• Robust thermal endurance: 5000-hour load life at 105°C supports extended reliability in elevated-temperature applications.
• High ripple tolerance: Specified LF and HF ripple currents (1.673 A at 120 Hz and 2.04 A at 200 kHz) enable stable performance under dynamic load conditions.
• Low impedance for stable power delivery: 28 mΩ impedance minimizes voltage drop and improves transient response.
• AEC-Q200 qualification: Explicit qualification for automotive electronics provides a verifiable foundation for vehicle-level designs.
• Compact high-capacitance can: φ16 × 35.5 mm radial can fits applications requiring substantial bulk capacitance in a small footprint.
• Compliance and reliability: RoHS compliant and manufactured by Nichicon as part of the UPM series with a focus on low impedance and high reliability.
