UPW1H122MHD

The UPW1H122MHD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, delivering 1200 µF capacitance at a 50 V rating. It is a miniature, low-impedance, high-reliability can-style capacitor designed for power supply and power-management applications.

Engineered for demanding environments, the part targets applications that require robust ripple handling, long endurance at elevated temperature, and AEC-Q200 qualification for automotive use.

Key Features

• Capacitance & Voltage: 1.2 mF (1200 µF) rated at 50 V, with a tolerance of −20% to +20% for bulk energy storage and smoothing.
• Low Loss / Low Impedance: Specified impedance of 56 mΩ and tanδ 0.1 measured at 20°C, 120 Hz, supporting efficient filtering in power stages.
• High Ripple Current Capacity: Low-frequency ripple current 2.295 A (120 Hz) and high-frequency ripple current 2.7 A (10 kHz), enabling effective decoupling across switching frequencies.
• Wide Temperature Range & Endurance: Operating from −55°C to +105°C with rated endurance of 8000 hours at 105°C, suitable for long-life thermal environments.
• Mechanical / Mounting: Radial lead, can-style package with diameter φ16 mm and length 30.5 mm; lead spacing 7.5 mm (±0.5 mm) for through-hole assemblies.
• Leakage Current & Polarization: Leakage current specified at 1800 µA; polarized electrolytic construction for DC applications.
• Automotive Grade: AEC-Q200 rated, aligning the component to automotive electronic subsystem requirements.
• Packaging & Availability: Available in bulk (no terminal forming) or bag packing; status: mass production.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering where low impedance and high ripple capability improve regulator stability and transient response.
• Automotive Electronics: Energy storage and decoupling in automotive control modules and power subsystems that require AEC-Q200 qualification and extended high-temperature endurance.
• DC–DC Converters: Input and output filtering for converters operating across low and high switching frequencies, leveraging the specified LF and HF ripple currents.

Unique Advantages

• High ripple-handling capability: Specified LF and HF ripple currents (2.295 A @120 Hz, 2.7 A @10 kHz) that support switching and high-frequency power stages.
• Low ESR/Impedance: 56 mΩ impedance and low tanδ (0.1 at 20°C, 120 Hz) reduce power loss and thermal stress in high-current circuits.
• Long high-temperature life: 8000 hours at 105°C provides longevity in thermally demanding installations.
• Automotive qualification: AEC-Q200 rating offers assurance for use in automotive-grade electronic systems.
• Compact radial-can form factor: φ16 × 30.5 mm package with 7.5 mm lead spacing enables straightforward through-hole mounting and replacement in legacy boards.
• Production readiness: Mass production status and standard packaging options simplify procurement and assembly planning.
