ULD1H010MDD

The ULD1H010MDD is a radial-lead aluminum electrolytic capacitor in a compact φ5×11 mm can, delivering 1 µF capacitance at a 50 V rating. It is a miniature, long-life component intended for general-purpose electronic applications where a small form factor, reliable DC filtering and decoupling are required.

Key value drivers include a wide operating temperature range of -40 °C to 105 °C, a rated endurance of 10,000 hours at 105 °C, low leakage current and measurable ripple current performance across low and high frequencies—making it suitable for space-constrained power and signal-conditioning circuits.

Key Features

• Capacitance & Tolerance — 1 µF nominal with tolerance of -20% to +20%, appropriate for decoupling and AC bypass in small-signal and power-rail applications.
• Voltage Rating — 50 V rated voltage for higher-voltage rail applications within its rated temperature range.
• Low Leakage — Leakage current specified at 3 µA, reducing standby losses and aiding in stable bias conditions.
• Loss Factor (tan δ) — tan δ = 0.19 measured at 20 °C, 120 Hz, providing a quantified dissipation characteristic for AC and ripple conditions.
• Ripple Current Capability — Low-frequency ripple current of 10.5 mA (120 Hz) and high-frequency ripple current of 25 mA (100 kHz), supporting both mains-frequency and higher-frequency switching environments.
• Long-Life Endurance — Rated life of 10,000 hours at 105 °C under specified conditions to support sustained operation in warm environments.
• Robust Temperature Range — Operates from -40 °C to 105 °C for broad environmental compatibility.
• Compact Radial Package — φ5×11 mm can with 2.0 mm lead spacing (±0.5 mm) and radial lead mounting for reliable through-hole installation; available in bulk or bag packing.
• RoHS Compliant — Manufactured in compliance with RoHS requirements.

Typical Applications

• LED driver and small power supplies — 50 V rating and long-life endurance make this capacitor suitable for smoothing and filtering in compact LED driver and low-power supply circuits.
• Decoupling and transient suppression — 1 µF capacitance and low leakage provide effective decoupling on small, space-constrained power rails and control lines.
• Signal conditioning in general-purpose electronics — Useful for AC coupling, timing, and noise suppression in consumer and industrial control boards.

Unique Advantages

• Compact footprint: The φ5×11 mm can minimizes board area while providing electrolytic capacitance for small-module designs.
• Measured performance data: Specified tan δ, leakage and ripple current values give designers verifiable parameters for thermal and AC-stress analysis.
• High-temperature endurance: 10,000 hours at 105 °C supports longer operational life in elevated-temperature enclosures.
• Through-hole reliability: Radial lead package with defined lead spacing simplifies mechanical retention and soldering in assembled boards.
• Low standby loss: 3 µA leakage current helps preserve battery life and reduce power consumption in idle conditions.
• Regulatory compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
