UPS2G4R7MPD

The UPS2G4R7MPD from Nichicon is a miniature, low-impedance aluminum electrolytic capacitor designed for switching power supply applications and general-purpose high-voltage use. It is a polarized, radial-lead cylindrical can optimized for compact power designs that require a 400 V rating in a small footprint.

Key value comes from its high-voltage capability, compact dimensions, and wide operating temperature range, making it suitable where space, reliability and high-voltage decoupling are priorities.

Key Features

• Capacitance & Voltage: 4.7 µF nominal capacitance with a 400 V rated voltage suitable for high-voltage rails and power supply stages.
• Miniature Package: Compact radial can with dimensions L: 2 × D: 1 cm and 5 mm lead spacing for dense PCB layouts and tight component placement.
• Low Impedance Performance: Engineered as a low-impedance type for switching power supplies, supporting improved ripple handling and stability in power circuits.
• Temperature & Lifetime: Rated for operation from −40 °C to +105 °C with a lifetime of 2000 hours at 105 °C, supporting designs that require sustained operation at elevated temperatures.
• Ripple Current Capability: Specified ripple current of 43 mA at 120 Hz and 68.8 mA at 10 kHz, useful for evaluating AC stress in switching circuits.
• Polarized Radial Lead: Polarized capacitor in a radial-lead can package for through-hole mounting and reliable electrical connection.
• Capacitance Tolerance: ±20% tolerance (−20% to +20%) at 120 Hz, 20 °C for design margin planning.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863), supporting regulatory and environmental requirements.

Typical Applications

• Switching Power Supplies — Bulk decoupling and smoothing on high-voltage rails in switch-mode power supplies where a compact, high-voltage capacitor is required.
• General-Purpose Power Circuits — High-voltage decoupling and energy storage for power stages and ancillary circuits that benefit from a small footprint.
• High-Voltage Electronics — Use on PCB assemblies that require polarized electrolytic capacitance at voltages up to 400 V while conserving board space.

Unique Advantages

• Compact high-voltage solution: 400 V rating in a 2 × 1 cm footprint enables high-voltage designs in limited board area.
• Designed for switching supplies: Low-impedance construction and specified ripple current values make it suited to the AC stress characteristics of switching regulators.
• Robust thermal performance: −40 °C to +105 °C operating range and a 2000-hour life at 105 °C support reliable operation in elevated-temperature environments.
• Through-hole reliability: Radial leaded can package provides strong mechanical connection and easy soldering for serviceable or high-reliability assemblies.
• Regulatory compliance: RoHS conformity simplifies regulatory evaluation for commercial and industrial products.
