UCY2C181MHD6

The UCY2C181MHD6 is a miniature, high‑reliability aluminum electrolytic capacitor from Nichicon’s UCY series, provided in a radial‑lead can for through‑hole mounting. It delivers 180 µF at 160 V with a wide operating temperature range of −40°C to 105°C and a long rated life of 12,000 hours at 105°C.

Designed for demanding power applications, this component combines high ripple current capability, AEC‑Q200 qualification, and RoHS compliance, making it suitable for power supplies, ballast circuits and automotive electronic systems that require robust, long‑life capacitors.

Key Features

• Capacitance & Voltage: 180 µF nominal capacitance with a 160 V rated voltage and ±20% tolerance, suitable for medium‑voltage power filtering and energy storage.
• High ripple current performance: Low‑frequency ripple current of 1.05 A at 120 Hz and high‑frequency ripple capability of 2.1 A at 100 kHz to support demanding power conditioning.
• Long endurance at elevated temperature: Rated for 12,000 hours at 105°C under specified DC bias and ripple conditions, supporting long service life in thermal stress environments.
• Electrical characteristics: Tangent of loss angle (tan δ) max 0.20 at 20°C/120 Hz and specified leakage current of 1252 µA.
• Package & mounting: Radial lead can in a compact footprint (φ12.5 × 35.5 mm) with 5.0 mm lead spacing (±0.5 mm) for reliable through‑hole assembly.
• Quality & compliance: AEC‑Q200 qualified and RoHS compliant for regulated environments and automotive‑grade applications.

Typical Applications

• Power supplies: Bulk filtering and smoothing in board‑level and chassis‑level power conversion circuits where high ripple handling and long life are required.
• Ballast circuits: Energy storage and ripple attenuation in lighting ballast designs and similar high‑stress AC/DC circuits.
• Automotive electronic systems: Power conditioning and decoupling in automotive electronics where AEC‑Q200 qualification is required.
• Industrial power conversion: DC link and filtering duties in industrial converters and control modules operating across a wide temperature range.

Unique Advantages

• Extended high‑temperature life: 12,000‑hour endurance rating at 105°C provides predictable lifetime performance in thermally demanding applications.
• Strong ripple handling: High low‑ and high‑frequency ripple current ratings (1.05 A @120 Hz, 2.1 A @100 kHz) reduce thermal stress and improve reliability under load.
• AEC‑Q200 qualification: Meets automotive component qualification standards, supporting use in vehicle electronics and other regulated sectors.
• Compact radial package: φ12.5 × 35.5 mm can and radial leads simplify through‑hole mounting while conserving PCB area for dense assemblies.
• Regulatory compliance: RoHS compliant for environmental regulation alignment.
