UHV1A102MPD

The UHV1A102MPD is a radial-leaded aluminum electrolytic capacitor in Nichicon’s UHV series engineered for general-purpose power applications that require low impedance and high ripple-current capability. This 1000 µF, 10 V polarized capacitor delivers a compact, through-hole form factor (φ10 × 12.5 mm) with a 5 mm lead spacing for straightforward mounting and prototyping.

Designed to operate from −40°C to 105°C with a rated endurance of 6000 hours at 105°C, the UHV1A102MPD targets applications where sustained high-frequency ripple handling, thermal robustness and compact size are important design priorities.

Key Features

• Capacitance and Voltage — 1000 µF nominal capacitance at a rated voltage of 10 V, with a tolerance of ±20%.
• Low Impedance — Measured impedance of 133 mΩ supports effective smoothing and decoupling at higher frequencies.
• High Ripple Current — Rated low-frequency ripple current of 816 mA (120 Hz) and high-frequency ripple current of 1.36 A (100 kHz), suitable for switching environments.
• Loss Characteristics — Tangent of loss angle (tan δ) specified (max. 0.18 at 10 V, 120 Hz, 20°C) for predictable AC performance.
• Thermal Endurance — Operating temperature range −40°C to 105°C with life/endurance rated at 6000 hours at 105°C under rated ripple and DC bias conditions.
• Leakage Current — Specified leakage current of 100 µA after voltage application (measurement condition: 20°C, 2 minutes).
• Radial Lead Package — Through-hole radial can package (φ10 × 12.5 mm) with 5 mm lead spacing and bulk/bag packing options for flexible assembly and inventory handling.
• RoHS Compliant — Meets RoHS directive requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Low impedance and high ripple current ratings support output filtering and smoothing in DC–DC converters and switch-mode supplies.
• Bulk Energy Storage — High capacitance in a compact radial can provides local energy storage for hold-up and transient support in general-purpose electronics.
• Power Rail Decoupling — Effective decoupling for power rails where low ESR/impedance at higher frequencies improves regulation and transient response.

Unique Advantages

• High ripple tolerance: 1.36 A at 100 kHz and 816 mA at 120 Hz provide margin for demanding switching and ripple-loaded circuits.
• Low impedance across frequency: 133 mΩ impedance supports improved filtering and reduced voltage ripple at higher frequencies.
• Compact through-hole form: φ10 × 12.5 mm radial can and 5 mm lead spacing deliver a small footprint for space-constrained PCBs while keeping the ease of through-hole assembly.
• Extended high-temperature life: 6000 hours endurance at 105°C enables reliable long-term operation in thermally stressed environments.
• Predictable AC behavior: Specified tan δ and leakage current values give designers measurable parameters for stability and loss budgeting.
• Regulatory compliance: RoHS compliance supports deployment in assemblies that require restricted-substance conformity.
