UPM1H222MHD

The UPM1H222MHD is a miniature radial-lead aluminum electrolytic capacitor engineered for high-reliability power applications. It delivers 2.2 mF capacitance at a 50 V rating in a compact φ18 × 40 mm can with radial leads and 7.5 mm lead spacing.

Designed for demanding environments, this AEC-Q200 qualified, RoHS-compliant device combines low impedance and high ripple-handling capability with extended endurance (5,000 hours at 105°C), making it suitable for systems that require durable power smoothing and decoupling under elevated temperature and vibration conditions.

Key Features

• Capacitance and Voltage — 2.2 mF (2,200 µF) rated at 50 V for bulk energy storage and decoupling in mid-voltage power rails.
• Low Impedance — 24 mΩ impedance supports lower ripple voltage and improved transient response in power circuits.
• High Ripple Current Capability — Low-frequency ripple current of 2.736 A (120 Hz) and high-frequency ripple current of 2.51 A (200 kHz) to handle continuous AC stress on the capacitor.
• High Reliability Endurance — Qualified for 5,000 hours of load life at 105°C, providing predictable performance in elevated-temperature environments.
• Temperature Range — Operating from −55°C to +105°C to support a wide range of ambient conditions.
• Electrical Loss Characteristic — tanδ of 0.12 (measured at 20°C, 120 Hz) for this rated capacitance and voltage.
• Leakage Current — Specified leakage current of 3,300 µA for initial performance verification.
• Package and Mounting — Radial lead, can package (φ18 × 40 mm) with 7.5 mm lead spacing (±0.5 mm); available in bulk or bag packing for production handling.
• Automotive-Grade Qualification — AEC-Q200 rated, supporting use in automotive systems where that qualification is required.
• Compliance — RoHS compliant.

Typical Applications

• Automotive power electronics — Bulk smoothing and decoupling on 12 V/48 V vehicle power rails where AEC-Q200 qualification and high ripple tolerance are required.
• ECU and control modules — Energy buffering and transient suppression in electronic control units operating up to +105°C.
• Power distribution modules — Filtering and stabilization of intermediate bus voltages that demand low impedance and sustained ripple handling.
• Industrial and embedded systems — High-reliability decoupling in temperature-challenging environments requiring long endurance and RoHS compliance.

Unique Advantages

• Long-term high-temperature endurance: 5,000 hours at 105°C provides predictable lifetime performance for thermal-stressed designs.
• Automotive-grade qualification: AEC-Q200 rating supports integration into automotive and other demanding systems that require component-level reliability assurance.
• High ripple capability with low impedance: 2.736 A (120 Hz) and 2.51 A (200 kHz) ripple ratings combined with 24 mΩ impedance reduce voltage ripple and improve power stability.
• Compact radial-lead form factor: φ18 × 40 mm can with 7.5 mm lead spacing enables straightforward through-hole mounting and robust mechanical connections.
• Clear electrical characterization: Specified tanδ (0.12 at 20°C, 120 Hz) and measured leakage current (3,300 µA) help engineers verify end-of-life and performance margins during design.
• Production-ready packaging: Available in bulk or bag packing for flexible procurement and assembly workflows; part is in mass production.
