UCY2D151MHD6

The UCY2D151MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a radial-lead, polarized capacitor specified at 150 µF and 200 V, designed for applications that require sustained ripple handling and long operational life in elevated temperatures.

Key attributes include a rated temperature range of −40°C to +105°C, endurance of 10,000 hours at 105°C, AEC-Q200 qualification, and RoHS compliance. The part is in mass production and supplied in bulk or bag packing.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with a rated voltage of 200 V and a tolerance of −20% to +20% for predictable filtering and energy storage.
• High Ripple Current Handling — Designed for high ripple environments with 910 mA at 120 Hz (low frequency) and 1.82 A at 100 kHz (high frequency), supporting demanding power supply applications.
• Long Life / High Temperature Endurance — Rated for 10,000 hours at 105°C, meeting long-life endurance requirements for sustained operation at elevated temperatures.
• Thermal and Loss Characteristics — Specified tangent of loss angle (tan δ) of 0.20 at 20°C/120 Hz, providing defined dissipation characteristics for design margins.
• Compact Radial Package — Can dimension φ18 × 20L with 7.5 mm lead spacing (±0.5 mm), offering a compact radial-can footprint for through-hole assemblies.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant, supporting regulated and automotive-capable designs.

Typical Applications

• Automotive power systems — Smoothing and decoupling in vehicle power electronics where AEC-Q200 qualification and high-temperature endurance are required.
• Power supplies — Bulk filtering and ripple absorption in AC/DC and DC/DC converters that require sustained ripple current capability.
• Ballasts and lighting drivers — Energy storage and ripple damping in ballast applications referenced in the UCY series documentation.
• Industrial power modules — Local energy storage and noise suppression in industrial converters and controllers operating across −40°C to +105°C.

Unique Advantages

• High ripple-current capability: With 910 mA at 120 Hz and 1.82 A at 100 kHz, the UCY2D151MHD6 supports applications with significant AC stress without compromising performance.
• Extended high-temperature lifetime: 10,000 hours at 105°C provides predictable end-of-life behavior for designs intended for extended operation in hot environments.
• AEC-Q200 qualified: The AEC-Q200 rating and explicit automotive application listing make this capacitor suitable for vehicle electronics that require proven component qualification.
• Compact radial form factor: φ18 × 20L can and 7.5 mm lead spacing enable space-efficient through-hole placement while keeping robust mechanical lead connections.
• Controlled loss characteristics: Specified tan δ (0.20 at 20°C/120 Hz) and defined leakage current behavior aid predictable thermal and electrical design margins.
• Regulatory compliance: RoHS compliance supports use in regulated markets and simplifies material-conformance tracking.
