UCS2D151MHD

The UCS2D151MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCS series, supplied in a radial‑lead can. It delivers 150 µF capacitance at a 200 V rating with a compact φ16 × 25 mm footprint and 7.5 mm lead spacing.

Designed for general-purpose electronic equipment and explicitly suited for power supply and ballast applications, this part provides high ripple current capability and long operational life for demanding thermal and electrical environments.

Key Features

• Capacitance & Tolerance — 150 µF with a tolerance of -20% to +20% (measured at 120 Hz, 20°C).
• Rated Voltage — 200 V DC rating suitable for higher-voltage supply circuits.
• High ripple current handling — Low-frequency ripple current: 945 mA at 120 Hz; high-frequency ripple current: 1.89 A at 100 kHz, supporting high-demand power applications.
• Loss characteristics — tanδ (DF) specified at 0.20 (measurement condition: 20°C, 120 Hz), enabling predictable dissipation behavior.
• Leakage current — Specified leakage current of 1300 µA (after 1 minute at 20°C under rated voltage), for reliable bias behavior.
• Long lifetime — Endurance rated for 10000 hours at 105°C under DC bias plus rated ripple current, for extended service in high-temperature environments.
• Operating temperature range — −40°C to +105°C, covering a wide range of environmental conditions.
• Package and dimensions — Radial lead can, case size φ16 × 25 mm with 7.5 mm lead spacing and lead diameter per datasheet; available in bulk or bag packing.
• RoHS compliant — Conforms to RoHS requirements.

Typical Applications

• Power supplies — Suited for power supply applications where 200 V rating and high ripple current acceptance are required.
• Ballasts — Designed for ballast applications as noted in product documentation, providing stable capacitance and long life at elevated temperatures.
• General-purpose electronic equipment — Useful in a variety of general-purpose circuits that require a compact, high-reliability electrolytic capacitor.

Unique Advantages

• High ripple capability — Dual-frequency ripple current specs (945 mA at 120 Hz and 1.89 A at 100 kHz) let designers account for both low- and high-frequency stress in power circuits.
• Extended high-temperature life — Rated endurance of 10000 hours at 105°C supports longer maintenance intervals and predictable aging in hot environments.
• Compact radial package — φ16 × 25 mm can with 7.5 mm lead spacing provides a small footprint for through-hole designs without sacrificing performance.
• Clear electrical parameters — Specified tanδ, leakage current, and tolerance provide engineers the data needed to model dissipation and bias behavior accurately.
• Regulatory compliance — RoHS compliance supports use in assemblies targeting current environmental requirements.
