UPS1E4R7MDD

The UPS1E4R7MDD from Nichicon is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supply and general‑purpose power filtering applications. It is a radial‑lead, polarized can that delivers 4.7 µF capacitance at a 25 V rating in a compact footprint.

Engineered for compact assemblies and elevated operating conditions, this part supports an ambient range of −55°C to +105°C and is RoHS compliant, making it suitable for a variety of board‑level power‑rail decoupling and smoothing tasks.

Key Features

• Capacitance & Voltage  4.7 µF capacitance with a 25 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Miniature Radial Can Package  Radial lead (can) package with 2.0 mm lead spacing and compact dimensions (L: 1.1 × D: 0.5 cm) for tight PCB layouts.
• Wide Temperature Range  Rated for operation from −55°C to +105°C to accommodate demanding thermal environments.
• Low Impedance Design  Specified as a low‑impedance type suited for switching power supply applications where reduced ESR is beneficial.
• Ripple Current Capability  Rated ripple current: 27.2 mA at 120 Hz and 160 mA at 10 kHz, supporting ripple handling across common switching frequencies.
• Endurance at Elevated Temperature  Designed for 2000 hours at 105°C, indicating suitability for sustained operation at high temperature limits.
• RoHS Compliant  Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies  Used for output smoothing and decoupling in switching regulator circuits where low impedance and compact size are required.
• General‑Purpose Power Filtering  Suitable for board‑level bulk and bypassing tasks in a wide range of electronic products.
• Radial‑Lead PCB Assemblies  Radial lead format and 2.0 mm lead spacing enable straightforward insertion into through‑hole assemblies and mixed‑technology boards.
• High‑Temperature Environments  Capable of operation up to +105°C with defined endurance for applications exposed to elevated temperatures.

Unique Advantages

• Compact footprint: The small can size (L: 1.1 × D: 0.5 cm) and 2.0 mm lead spacing free PCB area for denser designs.
• Engineered for switching supplies: Low‑impedance construction and specified ripple current ratings target switching regulator performance needs.
• Wide temperature capability: −55°C to +105°C rating supports use across a broad range of thermal environments without derating the part family.
