UCS2D101MND9

The UCS2D101MND9 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UCS series, designed for compact power applications. It delivers 100 µF at 200 V in a miniature can-style package with polarized leads.

Engineered for high ripple environments and extended operating life, this capacitor is suited for power supply and ballast applications where elevated temperature endurance and reliable ripple performance are required. It is RoHS compliant.

Key Features

• Core Electrical — 100 µF capacitance with a 200 V rated voltage and ±20% tolerance, providing predictable bulk energy storage and filtering behavior.
• High Ripple Capability — Rated ripple currents of 630 mA at 120 Hz and 1.26 A at 100 kHz, supporting heavy ripple conditions in switching and ballast circuits.
• Extended Endurance — Load-life specification of up to 10000 hours at +105°C (8000 hours for some smaller case sizes), enabling long-term operation in high-temperature environments.
• Temperature Range — Wide operating range from −40°C to +105°C to accommodate demanding thermal environments.
• Compact Radial Can Package — Radial lead construction with 5 mm lead spacing and dimensions L: 4 × D: 1 cm for space-constrained board designs.
• Polarized Design — Intended for DC applications where correct polarity is observed.
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies — Bulk smoothing and ripple filtering in high-voltage DC power rails where elevated ripple current capability is required.
• Ballasts — AC/DC ballast and lamp drive circuits that demand durable capacitors able to withstand continuous ripple and elevated temperatures.
• General-Purpose Electronics — Applications requiring polarized aluminum electrolytic capacitors with compact size, high ripple tolerance, and long life.

Unique Advantages

• High ripple tolerance: Rated ripple currents at both low (120 Hz) and high (100 kHz) frequencies allow reliable operation in switching and ballast environments.
• Long operational life at elevated temperature: Endurance up to 10000 hours at +105°C reduces replacement frequency in high-temperature applications.
• Space-efficient footprint: Compact radial can (L: 4 × D: 1 cm) and 5 mm lead spacing help conserve PCB area without sacrificing performance.
• Wide temperature capability: −40°C to +105°C operating range supports use across diverse environmental conditions.
• Standards compliance: RoHS conformity supports regulatory requirements for electronic assemblies.
