Key Features

• Capacitance & Voltage — 4.7 μF rated capacitance with a 100 V rated voltage, suitable for high-voltage filtering in compact assemblies.
• Miniature Radial Can Package — Radial lead, can-style package with a compact footprint (1.1 cm × 0.5 cm), 2 mm lead spacing for through-hole mounting.
• Wide Temperature Range — Rated for operation from −55°C to +105°C, enabling use across broad environmental conditions.
• High Reliability Endurance — Rated lifetime of 2000 hours at 105°C (per UPS series specification), supporting sustained performance under elevated temperature stress.
• Low Impedance for Switching Supplies — Part of Nichicon’s UPS series specified as low impedance and intended for switching power supply applications.
• Ripple Current Capability — Specified ripple currents include 12.58 mA at 120 Hz and 74 mA at 10 kHz, supporting both low- and high-frequency AC content on DC rails.
• Tolerance & Polarization — ±20% capacitance tolerance at 20°C, polarized design for correct polarity-sensitive installations.
• RoHS Compliant — Complies with the RoHS directive.

Typical Applications

• Switching Power Supplies — Low-impedance behavior and rated ripple-current characteristics make it suitable for input/output filtering in switching regulators.
• General-Purpose Power Filtering — Used where compact, polarized high-voltage capacitance is required for smoothing and energy storage in power rails.
• Compact Power Modules and PCB Assemblies — Miniature radial-can package supports space-constrained through-hole designs that require reliable, high-voltage capacitors.
