UHW1K101MPD

The UHW1K101MPD is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon's UHW series. It is a radial‑lead, polarized electrolytic designed for general‑purpose power applications that require high ripple current handling and long operating life.

With a 100 µF capacitance at 80 V, low impedance, and a wide operating temperature range, this part is suited to compact designs that need robust smoothing, decoupling, and energy‑storage performance over extended endurance at elevated temperature.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 80 V and tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High ripple current capability — Specified ripple current of 632 mA at 120 Hz and 1.58 A at 10 kHz, supporting demanding AC ripple environments.
• Low impedance and dissipation — Low impedance (660 mΩ) and a tanδ (loss tangent) of 0.09 at 20°C, 120 Hz for effective high‑frequency performance.
• Long endurance — Rated endurance of 11,000 hours at 105°C under D.C. bias plus rated ripple current (peak voltage not to exceed rated voltage).
• Wide temperature range — Specified to operate from −40°C to +105°C for broad environmental tolerance.
• Compact radial can package — φ8 × 20 mm can size, radial lead mounting with 3.5 mm lead spacing (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Low leakage — Leakage current specified at 80 µA after rated voltage application conditions.
• RoHS compliant — Meets RoHS requirements as stated in the product data.

Typical Applications

• Power supplies — Bulk smoothing and decoupling where an 80 V rating, high ripple current, and compact size are required.
• Industrial controls — Energy storage and filtering in compact control electronics operating across −40°C to +105°C with long endurance.
• Instrumentation and consumer electronics — Local decoupling and transient suppression in space‑constrained boards that benefit from low impedance and high‑frequency ripple capability.

Unique Advantages

• Compact form factor with high performance — φ8 × 20 mm can provides 100 µF at 80 V while maintaining low impedance (660 mΩ), enabling space‑efficient designs.
• Designed for high ripple environments — Specified ripple currents at both 120 Hz and 10 kHz support applications with significant AC content across frequencies.
• Extended high‑temperature life — 11,000‑hour endurance at 105°C supports long service life in elevated‑temperature applications.
• Predictable electrical behavior — Low tanδ (0.09 at 20°C, 120 Hz) and controlled leakage (80 µA) help maintain stable performance in filtering and decoupling roles.
• Easy radial‑lead integration — Standard 3.5 mm lead spacing and common radial can package simplify through‑hole PCB integration and assembly.
• Regulatory compliance — RoHS compliance for use in regulated product stacks.
