UPW1V222MHD6

The UPW1V222MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UPW series. It combines high capacitance (2.2 mF) with low impedance and elevated ripple-current capability to support power conversion and energy-storage functions in compact assemblies.

Designed for demanding environments, the UPW1V222MHD6 offers long endurance at elevated temperature (8000 hours at 105°C) and AEC-Q200 qualification for automotive applications, making it suitable for switching power supplies and other high-reliability power electronics.

Key Features

• Capacitance & Voltage: 2200 µF (2.2 mF) rated at 35 V for bulk energy storage and decoupling on DC rails.
• Low impedance: 40 mΩ impedance supports tighter voltage regulation and lower ripple voltage under load.
• High ripple-current capability: 2.329 A at 120 Hz (low frequency) and 2.74 A at 10 kHz (high frequency) to handle switching currents in power supplies.
• High-temperature endurance: Rated operating temperature −55°C to +105°C with an endurance of 8000 hours at 105°C.
• Loss tangent (tan δ): 0.14 (measured at 20°C, 120 Hz), indicating the capacitor’s dissipation characteristics for thermal and AC performance assessments.
• Leakage current: 2310 µA (specified), useful for estimating standby losses and bias requirements.
• Compact radial package: φ18 × 25 mm can with 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for manual or machine assembly processes.
• AEC-Q200 qualified: Meets automotive-grade reliability requirements for designs that require qualification to automotive stress standards.

Typical Applications

• Switching Power Supplies: Output smoothing and bulk decoupling where high ripple current and low impedance improve regulation and transient response.
• Automotive Power Electronics: Energy storage and filtering in systems that demand AEC-Q200 qualification and high-temperature endurance.
• DC-DC Converters: Input/output filtering and hold-up capacitance for compact converter stages operating up to 35 V.

Unique Advantages

• High ripple handling: Specified ripple currents at both low and high frequencies reduce thermal stress and extend capacitor life in switching environments.
• Low series impedance: 40 mΩ impedance helps minimize voltage drop and dissipation under dynamic load conditions.
• Extended high-temperature life: 8000 hours at 105°C supports long-term reliability in elevated-temperature applications.
• Automotive-grade qualification: AEC-Q200 rating enables use in automotive designs that require qualified components.
• Compact radial form factor: φ18 × 25 mm can and 7.5 mm lead spacing offer a space-efficient solution for through-hole layouts.
• Series design for power supplies: UPW series emphasis on miniature size, low impedance, and high reliability aligns the part to switching power supply requirements.
