UCY2V151MHD

The UCY2V151MHD is a radial-lead, miniature aluminum electrolytic capacitor from Nichicon’s UCY series designed for high-reliability power applications. It delivers 150 µF at a 350 V rating with high ripple-current capability and long load life, targeting power supply smoothing, ballast circuits and automotive electronics requiring robust DC filtering.

Key value propositions include high ripple-current performance (up to 2.16 A at high frequency), extended endurance of 12,000 hours at 105 °C, and AEC-Q200 qualification for demanding environments.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 350 V and capacitance tolerance of −20% to +20%.
• High Ripple‑Current Capability — Low-frequency ripple current of 1.08 A at 120 Hz and high-frequency ripple current of 2.16 A at 100 kHz for effective smoothing under dynamic loads.
• Long Endurance — Rated for 12,000 hours at 105 °C under DC bias plus rated ripple current; capacitance change and leakage remain within the specified endurance limits after life test.
• Wide Operating Temperature — Operates from −40 °C to 105 °C to support a broad range of ambient conditions.
• Leakage Current — Specified leakage current of 2,200 µA (measurement conditions per datasheet).
• Radial Through‑Hole Package — φ18 × 35.5 mm can with 7.5 mm lead spacing (±0.5 mm) and radial lead mounting for straightforward through‑hole assembly and robust mechanical retention.
• AEC‑Q200 Qualified — Designed to meet AEC‑Q200 quality requirements for automotive and other high-reliability applications.
• RoHS Compliant — Meets RoHS directive requirements for environmentally regulated designs.

Typical Applications

• Power Supplies — Bulk smoothing and DC link filtering where 350 V rating and high ripple-current capacity improve voltage stability.
• Ballast and Lighting Electronics — High ripple handling and long life support continuous operation in ballast circuits.
• Automotive Electronics — AEC‑Q200 qualification and wide temperature range enable use in automotive power modules and auxiliary circuits.
• Industrial Power Control — Filtering and energy buffering in motor drives and industrial converters requiring reliable high-voltage capacitors.

Unique Advantages

• High-frequency ripple performance: 2.16 A ripple current rating at 100 kHz improves smoothing in switching regulator and inverter topologies.
• Extended operational life: 12,000‑hour endurance at 105 °C provides predictable longevity for continuous high-temperature use.
• Automotive-capable quality: AEC‑Q200 qualification supports deployment in transportation and other safety‑conscious applications.
• Compact radial form factor: φ18 × 35.5 mm can and 7.5 mm lead spacing balance capacitance and board-space efficiency for through‑hole assemblies.
• Measured leakage specification: Leakage current specified at 2,200 µA to allow accurate system power-loss budgeting.
• Regulatory compliance: RoHS compliance simplifies use in designs subject to environmental regulations.
