UCY2E101MHD6

The UCY2E101MHD6 is a polarized radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series, offering 100 µF capacitance at a 250 V rating. It combines a compact radial can package (φ12.5 × 35.5 mm) with high ripple-current capability and extended operational life for demanding power applications.

Designed for use in power supplies, ballast circuits and automotive-related electronics, this part delivers high ripple handling, a wide operating temperature range (−40 °C to 105 °C) and AEC‑Q200 qualification for applications requiring verified reliability.

Key Features

• Capacitance & voltage: 100 µF nominal capacitance with a 250 V rated voltage and a tolerance of −20% to +20% for predictable energy storage and filtering.
• High ripple-current capability: Low-frequency ripple current 785 mA (120 Hz) and high-frequency ripple current 1.57 A (100 kHz) support robust smoothing and decoupling in power circuits.
• Long life at elevated temperature: Rated for 12,000 hours at 105 °C under the specified endurance conditions to support extended field service life.
• Wide operating temperature: Specified from −40 °C to +105 °C to accommodate a broad range of environmental conditions.
• Electrical loss characteristic: tan δ (loss tangent) ≤ 0.20 measured at 20 °C, 120 Hz, enabling stable performance in AC ripple environments.
• Compact radial package: φ12.5 mm diameter × 35.5 mm length with 5.0 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for straightforward through-hole assembly.
• Reliability and standards: AEC‑Q200 qualified and RoHS compliant, suitable for designs that require documented supply-chain and quality controls.

Typical Applications

• Power supplies: Bulk filtering and output smoothing in AC/DC and DC/DC converters where high ripple current capability and long life are required.
• Ballasts and lighting drivers: Energy storage and ripple suppression in ballast and lamp-driver circuits referenced in the UCY series documentation.
• Automotive electronics: Power filtering and decoupling in automotive control modules and power systems, leveraging the AEC‑Q200 qualification and extended temperature range.
• Industrial power systems: Input/output filtering and transient absorption in industrial power supplies and motor-control power stages.

Unique Advantages

• Extended high-temperature endurance: 12,000 hours at 105 °C provides designers confidence for long-term operation in thermally stressed environments.
• High ripple handling across frequency: Rated ripple currents at both low and high frequencies (785 mA at 120 Hz and 1.57 A at 100 kHz) allow the capacitor to address a wide range of switching and line-frequency ripple conditions.
• Compact, serviceable radial format: The φ12.5 × 35.5 mm can with 5.0 mm lead spacing fits through-hole assembly flows and simplifies replacement and prototyping.
• Verified reliability for automotive use: AEC‑Q200 qualification indicates suitability for vehicle electronics where supplier qualification is required.
• Regulatory compliance: RoHS compliance supports environmentally constrained product builds and global market requirements.
