UVK2G101MHD

The UVK2G101MHD is a miniature aluminum electrolytic capacitor in Nichicon’s UVK series, configured as a radial‑lead polarized can. It delivers 100 µF capacitance at a 400 V rated voltage, targeting general‑purpose high‑voltage applications that require compact, through‑hole energy storage.

Designed for durability in demanding environments, this part offers a wide operating temperature range and specified endurance at elevated temperature, combined with measurable ripple current capabilities for AC stress handling.

Key Features

• Capacitance & Voltage: 100 µF rated capacitance with a 400 V working voltage suited to high‑voltage circuits requiring bulk storage in a compact package.
• Radial Lead Can Package: φ18 × 35.5 mm can (L: 3.55 × D: 1.8 cm) with 7.5 mm lead spacing and radial lead mounting for through‑hole assembly and secure mechanical retention.
• Temperature & Endurance: Operates from −40 °C to +85 °C with an endurance specification of 2000 hours at 85 °C under rated voltage.
• Ripple Current Performance: Specified low‑frequency ripple current of 440 mA at 120 Hz and high‑frequency ripple current of 704 mA at 10 kHz to quantify AC stress handling.
• Leakage & Dissipation: Leakage current specified at 1700 µA and tangent of loss angle (tan δ) of 0.25 measured at 20 °C, 120 Hz, providing measurable dielectric characteristics for design verification.
• Manufacturing & Compliance: Available in bulk/bag packing with RoHS compliance and listed as a mass‑production part for volume availability.

Typical Applications

• General‑purpose high‑voltage power circuits: Use where a 100 µF, 400 V polarized capacitor is required for energy storage or smoothing in through‑hole assemblies.
• Industrial control electronics: Suited to systems operating across −40 °C to +85 °C and requiring the 2000‑hour endurance rating at 85 °C for reliable long‑term operation.
• Power supply bulk storage: Compact φ18 × 35.5 mm can provides high‑voltage capacitance in applications that demand board space efficiency with radial lead mounting.
• AC ripple management in high‑voltage modules: Rated ripple current values at 120 Hz and 10 kHz allow designers to assess AC stress performance for filtering and decoupling tasks.

Unique Advantages

• High working voltage capability: 400 V rating enables use in higher‑voltage circuits without upsizing capacitance or footprint.
• Compact, miniature footprint: φ18 × 35.5 mm can size offers a smaller case compared with larger aluminum electrolytic options while maintaining 100 µF capacitance.
• Quantified ripple handling: Specified ripple currents at both low and high frequency (440 mA at 120 Hz, 704 mA at 10 kHz) let engineers size thermal and lifetime margins accurately.
• Temperature‑rated endurance: 2000 hours at 85 °C under rated voltage gives a defined lifetime parameter for reliability planning and maintenance scheduling.
• Regulatory readiness: RoHS compliance supports use in markets and products requiring restricted‑substance adherence.
