ULD1V101MPD

The ULD1V101MPD is a radial‑lead aluminum electrolytic capacitor from Nichicon's ULD series, offering 100 µF capacitance at a 35 V rating. It is a miniature, long‑life radial can designed for general‑purpose power filtering and smoothing in compact electronic assemblies, including LED driver power supplies.

Engineered for extended operation in elevated temperatures, this part delivers a combination of compact size, defined ripple handling, low leakage, and RoHS compliance for reliable service in industrial and consumer systems.

Key Features

• Capacitance and Voltage — 100 µF nominal capacitance with a rated voltage of 35 V and a tolerance of −20% to +20% at 120 Hz, 20°C.
• Low Loss — Tan δ (loss tangent) of 0.22 measured at 20°C, 120 Hz, supporting efficient energy handling in filtering applications.
• Ripple Current Performance — Rated low‑frequency ripple current of 231 mA at 120 Hz and high‑frequency ripple current of 330 mA at 100 kHz for handling AC components on DC rails.
• Leakage Current — Specified maximum leakage current of 35 µA after application of rated voltage, supporting low standby losses in power circuits.
• Long Life at Elevated Temperature — Endurance specified for 10,000 hours at +105°C under rated voltage and rated ripple conditions, suited for designs requiring extended high‑temperature reliability.
• Mechanical/Form Factor — Compact radial can: φ8 × 11.5 mm (diameter × length) with 3.5 mm lead spacing (±0.5 mm). Radial lead mounting for through‑hole assembly and prototyping.
• Packaging & Production Status — Available in bulk (no terminal forming) or bag packing; product status: mass production.
• Environmental Compliance — RoHS compliant.

Typical Applications

• LED Driver Power Supplies — Suited for smoothing and bulk decoupling in LED lighting power modules where compact, long‑life capacitors are required.
• General Power Filtering — Ideal for DC rail filtering, decoupling and ripple suppression in small power supplies and converters.
• Consumer and Industrial Electronics — Used for energy storage and transient suppression in compact control boards and embedded modules operating up to +105°C.

Unique Advantages

• High‑temperature endurance: Rated for 10,000 hours at +105°C, providing predictable lifetime behavior in thermally demanding designs.
• Compact footprint: φ8 × 11.5 mm can size enables space‑constrained layouts while retaining significant capacitance for filtering tasks.
• Defined ripple handling: Clear low‑ and high‑frequency ripple current ratings (231 mA at 120 Hz, 330 mA at 100 kHz) let designers size capacitors to expected AC load conditions.
• Low leakage: 35 µA maximum leakage current minimizes standby losses and supports power‑sensitive applications.
• Radial lead format: Through‑hole radial leads and standard 3.5 mm spacing simplify prototyping, hand‑assembly and wave/solder processes that accept radial components.
• Regulatory compliance: RoHS conformity for use in designs requiring restricted‑substance compliance.
