ULD1C151MED

The ULD1C151MED is a miniature, radial-lead aluminum electrolytic capacitor offering 150 µF capacitance at a 16 V rating. It is part of Nichicon’s ULD series designed for long-life assurance and compact through-hole applications.

Engineered for general-purpose power applications — including power supplies for LED lighting — this capacitor provides long operational life, controlled loss (tanδ), and stable performance across a wide temperature range.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20%.
• Loss Characteristic — tanδ (DF) of 0.35 measured at 20°C and 120 Hz for predictable AC loss behavior in filtering and smoothing applications.
• Ripple Current Handling — Low-frequency ripple current 147 mA at 120 Hz and high-frequency ripple current 210 mA at 100 kHz to support decoupling and power-supply ripple demands.
• Leakage Current — Rated leakage current of 24 µA for minimized standby losses.
• Long-Life Endurance — Rated for 10,000 hours at 105°C under specified conditions, supporting extended operational lifetimes in demanding environments.
• Temperature Range — Operates from −40°C to +105°C for broad environmental suitability.
• Package & Mounting — Radial lead, polarized can with dimensions Ø6.3 × 11 mm (L: 1.1 cm × D: 0.63 cm) and 2.5 mm lead spacing (±0.5 mm), available in bulk or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• LED Lighting Power Supplies — Suited for smoothing and energy storage in LED driver circuits where long life and stable performance at elevated temperature are required.
• General-Purpose Electronics — Applicable for general-purpose filtering, decoupling, and energy-storage tasks in through-hole designs.
• Space-Constrained Through-Hole Designs — Miniature can size (Ø6.3 × 11 mm) and compact lead spacing enable use in tight PCB layouts that require through-hole components.

Unique Advantages

• Long operational life: Specified for 10,000 hours at 105°C, helping extend maintenance intervals and product service life.
• Compact footprint: Small Ø6.3 × 11 mm can and 2.5 mm lead spacing reduce board area for through-hole implementations.
• Broad temperature tolerance: Rated from −40°C to +105°C to maintain capacitance and performance across common operating environments.
• Measured AC performance: Specified tanδ and ripple-current ratings at defined frequencies give predictable behavior in power-supply filtering roles.
• Low leakage: 24 µA leakage current supports low-loss standby and bias applications.
• RoHS compliant: Meets common regulatory requirements for restricted substances.
