UPS2D470MHD

The UPS2D470MHD is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon's UPS series, supplied in a radial lead can package. It is a polarized capacitor intended for general-purpose use and specifically noted for switching power supply applications.

This part combines a compact footprint with a high rated voltage and wide operating temperature range, offering designers a space-efficient energy-storage and filtering component for power circuitry.

Key Features

• Electrical Rating: 47 µF nominal capacitance with a rated voltage of 200 V and a tolerance of −20% to +20%, suitable for high-voltage power circuits.
• Low Impedance / Ripple Performance: Designed for low impedance behavior with rated ripple current of 220 mA at 120 Hz and 352 mA at 10 kHz to support switching regulator filtering and decoupling.
• Temperature and Lifespan: Rated for operation from −40 °C to +105 °C with an endurance rating of 3000 hours at 105 °C.
• Package and Mounting: Radial lead, can-style package with 5 mm lead spacing; compact dimensions L: 2.5 × D: 1.25 cm and seated height up to 2.5 cm for tight board layouts.
• Polarized Design: Polar capacitor construction for use in DC power circuits where polarity is defined.
• RoHS Compliance: Compliant with RoHS directive (2011/65/EU, (EU)2015/863), supporting environmentally conscious assemblies.

Typical Applications

• Switching Power Supplies: Bulk and output filtering where a compact, high-voltage electrolytic is required to smooth switching ripple and stabilize DC rails.
• General Purpose Power Circuits: Decoupling and energy storage in industrial and consumer power designs that require a polarized, high-voltage capacitor.
• Power Supply Modules: Local energy reservoir and ripple suppression in board-level power modules and converters with constrained PCB area.

Unique Advantages

• High Voltage Capacity: 200 V rated voltage enables use in higher-voltage power designs without upsizing capacitor form factor.
• Compact Footprint: Small can-style radial package and 5 mm lead spacing reduce board area impact while maintaining useful capacitance.
• Designed for Switching Environments: Specified ripple current values at 120 Hz and 10 kHz support performance in switching regulator and converter applications.
• Wide Operating Temperature: −40 °C to +105 °C temperature range and 3000-hour endurance at 105 °C provide predictable behavior in elevated-temperature environments.
• RoHS Conformant: Meets RoHS requirements for assemblies targeting restricted-substance compliance.
