Key Features

• Capacitance & Voltage: 100 µF rated at 250 V, providing a compact high-voltage storage element for through-hole designs.
• High Ripple Current: Rated ripple performance of 765 mA at 120 Hz and 1.53 A at 100 kHz supports demanding AC ripple conditions.
• Long Life at Elevated Temperature: Rated for 10000 hours at +105°C under specified load life conditions, suitable for long-term high-temperature operation.
• Wide Operating Temperature Range: Specified for –40°C to +105°C to cover a broad set of industrial environments.
• Radial Lead, Can Package: Radial lead mounting with a can-style package and 7.5 mm lead spacing simplifies PCB layout for through-hole assemblies.
• Compact Footprint: Physical size L: 2.5 cm × D: 1.6 cm offers a miniature solution for space-constrained designs.
• Polarized Construction & Tolerance: Polarized capacitor with ±20% capacitance tolerance at 120 Hz, 20°C.
• RoHS Compliance: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Used where high-voltage, compact capacitance and high ripple handling are required in through-hole power supply stages.
• Ballasts — Suited for ballast applications that require stable performance and long life at elevated temperatures.
• General Purpose Electronics — Applicable to a broad range of general-purpose circuits needing a polarized, high-voltage electrolytic capacitor.

Unique Advantages

• High ripple tolerance: Specified ripple currents (765 mA at 120 Hz; 1.53 A at 100 kHz) allow the capacitor to handle significant AC stress in power applications.
• Extended high‑temperature life: 10000 hours rated life at +105°C provides predictable longevity in thermally demanding installations.
• Small, through‑hole form factor: Compact 2.5 cm × 1.6 cm can and 7.5 mm lead spacing enable use where board space is limited while retaining robust mounting.
• Simple integration: Radial lead, polarized can package fits standard through-hole assembly processes for quick integration into existing designs.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted-substance compliance.
• Clear manufacturer pedigree: Manufactured by Nichicon and part of the UCS series, providing traceable specification and datasheet-backed performance.
