UTHW6131MND

The UTHW6131MND from Nichicon is a high-voltage, miniature aluminum electrolytic capacitor in the UTH series designed for general-purpose applications. It is a polarized, radial-lead, can-style capacitor offering 130 µF capacitance at a 420 V rated voltage.

Engineered for compact high-voltage circuits, the UTHW6131MND delivers long-life performance with specified endurance at elevated temperature and clear electrical characteristic limits for design verification.

Key Features

• Electrical Rating — 130 µF nominal capacitance with a 420 V rated voltage and capacitance tolerance of ±20% at 120 Hz, 20°C.
• High-Voltage, Miniature Format — Miniature radial can construction with dimensions L: 3.15 cm × D: 1.8 cm and 7.5 mm lead spacing for compact board layouts.
• Wide Temperature Range — Operational temperature range from −40°C to +105°C, supporting high-temperature operating environments.
• Long Life / Endurance — Rated for 5000 hours at 105°C under D.C. bias plus rated ripple current; after the endurance test, capacitance remains within ±20%, tan δ remains within 200% of initial specified value, and leakage current is maintained at or below initial specified limits.
• Ripple Current Performance — Rated ripple current of 860 mA at 120 Hz and 1.376 A at 10 kHz; frequency coefficients per the series: 1.00 at 120 Hz and 1.60 at 10 kHz~ for estimating ripple capability across frequency.
• Loss and Leakage Characteristics — Maximum tan δ of 0.20 (measured at 120 Hz, 20°C for 420 V), and leakage current defined by the datasheet formulas: after 1 minute ≤ 0.04CV + 100 µA and after 5 minutes ≤ 0.02CV + 25 µA (at 20°C).
• Mounting & Polarity — Polarized device with radial lead mounting suitable for through-hole assembly; marked with white printing on a dark brown sleeve for identification.

Typical Applications

• General-purpose high-voltage circuits — Provides energy storage and smoothing in compact circuits that require a 420 V rated electrolytic capacitor.
• Compact power modules — Suited to space-constrained designs needing a miniature radial-lead, high-voltage capacitor with defined ripple and endurance specifications.
• Industrial electronics — Applicable where long life at elevated temperature and predictable leakage/tan δ behavior are required for reliability planning.

Unique Advantages

• High-voltage capability: 420 V rating enables use in higher-voltage DC circuits without the need for series stacking of lower-voltage parts.
• Compact footprint: Small L × D dimensions and 7.5 mm lead spacing reduce board area for high-voltage capacitors in compact designs.
• Documented endurance: 5000 hours at 105°C under rated stress gives a measurable baseline for long-term performance planning.
• Predictable ripple behavior: Specified ripple currents at 120 Hz and 10 kHz and frequency coefficients allow straightforward ripple budgeting across frequency bands.
• Clear loss and leakage limits: Defined tan δ and leakage current limits (including time-based leakage formulas) support accurate electrical modeling and QA checks.
