UCY2D181MHD6

The UCY2D181MHD6 is a miniature, radial‑lead aluminum electrolytic capacitor from Nichicon’s UCY series designed for high ripple current and long life applications. It provides 180 µF capacitance at a rated voltage of 200 V in a compact φ16 × 25 mm can, optimized for power electronics and automotive electronics where sustained ripple handling and elevated temperature endurance are required.

This AEC‑Q200 qualified, RoHS‑compliant component combines high frequency ripple capability with a −40 °C to +105 °C operating window and a rated life of 12,000 hours at 105 °C, making it suitable for demanding systems that require reliable energy storage under sustained load.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with ±20% tolerance and a rated voltage of 200 V, providing stable bulk energy storage for mid‑voltage power rails.
• High Ripple Current — Rated low‑frequency ripple current of 1.035 A (120 Hz) and high‑frequency ripple current of 2.07 A (100 kHz), enabling use in high‑stress ripple environments.
• Long Life & Endurance — Rated endurance of 12,000 hours at 105 °C under DC bias plus rated ripple current; capacitance change and leakage are specified after recovery to 20 °C.
• Temperature Range & Reliability — Operating temperature −40 °C to +105 °C with AEC‑Q200 qualification and RoHS compliance for automotive and industrial reliability requirements.
• Electrical Characteristics — Tangent of loss angle (tan δ) of 0.20 at 20 °C, 120 Hz; specified leakage current of 1,540 µA for the part as produced.
• Package & Mounting — Radial lead can (φ16 × 25 mm) with 7.5 mm lead spacing (±0.5 mm), leaded mounting for through‑hole assemblies; available in bulk or bag packing.

Typical Applications

• Automotive Electronics — Energy storage and smoothing in automotive power circuits where AEC‑Q200 qualification and high ripple endurance are required.
• Power Supplies & DC‑DC Converters — Bulk filtering and ripple attenuation on mid‑voltage rails, taking advantage of the capacitor’s high ripple current ratings.
• Lighting Ballasts — Designed for ballast and power‑conditioning applications where continuous ripple and elevated operating temperatures are common.
• High‑Ripple Circuits — Suitable for circuits that demand sustained ripple handling across a broad frequency range, leveraging the specified low and high frequency ripple currents.

Unique Advantages

• High ripple capability: Explicit low‑ and high‑frequency ripple current ratings (1.035 A at 120 Hz, 2.07 A at 100 kHz) reduce the need for parallel devices in ripple‑intensive designs.
• Extended thermal endurance: 12,000‑hour rated life at 105 °C supports long service intervals in elevated‑temperature environments.
• Automotive qualification: AEC‑Q200 rating provides a verifiable reliability credential for automotive and similarly demanding applications.
• Compact radial can: φ16 × 25 mm package with 7.5 mm lead spacing offers a small footprint for through‑hole assemblies while maintaining required capacitance.
• Traceable electrical specs: Clear tan δ, leakage, and tolerance figures enable straightforward selection and calculation for filter and energy‑storage designs.
• Regulatory compliance: RoHS compliant for global manufacturing requirements.
