UTHW6141MND

The UTHW6141MND from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in the UTH series. It is a radial‑lead, polarized capacitor rated at 420 V with a nominal capacitance of 140 µF and a capacitance tolerance of ±20%.

Designed for general-purpose high-voltage applications, this part offers long endurance (5000 hours at 105°C), compact φ16 × 40 mm packaging, and measurable ripple current capability across low and high frequencies—providing a balance of voltage rating, lifetime, and size for engineers specifying high-voltage electrolytic solutions.

Key Features

• Capacitance and Voltage — 140 µF nominal capacitance with a 420 V rated voltage and ±20% tolerance, suitable where high DC voltage handling is required.
• High‑Temperature Endurance — Rated lifetime of 5000 hours at 105°C under specified DC bias plus rated ripple current, enabling prolonged operation in elevated ambient temperatures.
• Ripple Current Performance — Low‑frequency ripple current of 910 mA at 120 Hz and high‑frequency ripple current of 1.456 A at 10 kHz, supporting designs with both network and switching ripple components.
• Low Loss (tan δ) — Specified tan δ (DF) of 0.20 measured at 20°C and 120 Hz, providing predictable dissipation characteristics for thermal design.
• Leakage Current — Leakage current specified as 2452 µA, stated under the product’s test conditions for predictable startup and bias behavior.
• Compact Radial Package — φ16 × 40 mm can with radial leads and 7.5 mm lead spacing (±0.5 mm) for through‑hole mounting and straightforward PCB layout and assembly.
• Packaging & Availability — Available in bulk (no terminal forming) or bag packing; status: mass production from Nichicon.

Typical Applications

• High‑voltage power electronics — Use where a 420 V rated capacitor with long operational life and measurable ripple current capability is required.
• Industrial equipment — Suited to general-purpose roles in systems that demand extended endurance at elevated temperatures (up to 105°C).
• Compact through‑hole designs — The φ16 × 40 mm radial package and 7.5 mm lead spacing allow integration into space-constrained PCBs that require polarized high‑voltage capacitance.

Unique Advantages

• Long operational life: 5000 hours at 105°C provides extended serviceability in high-temperature environments, reducing maintenance and replacement cycles.
• High-voltage capability in a small footprint: 420 V rating combined with a φ16 × 40 mm can delivers substantial voltage margin without a large board area.
• Frequency‑versatile ripple handling: Specified ripple currents at 120 Hz and 10 kHz support designs that encounter both line-frequency and switching-frequency ripple.
• Predictable loss and leakage characteristics: tan δ of 0.20 and a defined leakage current value enable accurate thermal and startup current budgeting.
• Radial lead convenience: Through‑hole radial leads with defined 7.5 mm spacing simplify PCB mounting and manual or automated insertion processes.
• Production readiness: Mass production availability with bulk or bag packing options to match assembly and stocking preferences.
