UCY2C101MHD

The UCY2C101MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UCY series. It is a polarized, radial-lead can designed for high ripple-current applications and long operational life in demanding environments.

Key use cases include automotive and power-supply systems where sustained ripple handling, elevated temperature endurance, and compact packaging are required. The part combines a 100 µF capacitance at 160 V with a long-life construction rated for extended operation at 105°C.

Key Features

• Electrical Performance — Capacitance & Voltage: 100 µF nominal capacitance with a rated voltage of 160 V and tolerance of −20% to +20%.
• Low Loss (tan δ): Tangent of loss angle (tan δ) specified at 0.20 measured at 20°C, 120 Hz for stable AC performance.
• High Ripple-Current Capability: Low-frequency ripple current of 645 mA at 120 Hz and high-frequency ripple current of 1.29 A at 100 kHz, supporting high-stress power circuits.
• Leakage Current: Typical leakage current listed as 740 µA, suitable for power applications where controlled DC leakage is required.
• Reliability & Endurance: Rated life of 10,000 hours at 105°C; designed to meet the UCY series long-life endurance requirements.
• Thermal Range: Operates from −40°C to +105°C, enabling use across wide ambient conditions.
• Mechanical & Package: Radial lead can, size φ12.5 × 20 mm (diameter × length), lead spacing 5 mm (±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Quality & Compliance: AEC-Q200 qualified and RoHS compliant; part is in mass production.

Typical Applications

• Automotive power electronics: Energy smoothing and decoupling in vehicle power systems where AEC-Q200 qualification and extended temperature range are required.
• Power supplies and ballasts: Bulk and smoothing capacitor for high-ripple supply outputs and ballast circuits, leveraging the part’s high ripple-current ratings.
• High-ripple current circuits: Circuits with sustained AC loading that need capacitors rated for elevated ripple current and long life at 105°C.

Unique Advantages

• High ripple-current tolerance: Supports 645 mA at 120 Hz and 1.29 A at 100 kHz, reducing temperature rise under AC stress and improving system stability.
• Extended high-temperature life: 10,000 hours at 105°C offers predictable lifetime performance for designs expected to operate at elevated temperatures.
• Compact radial can format: φ12.5 × 20 mm footprint with 5 mm lead spacing provides a small form factor for power-dense assemblies.
• AEC-Q200 qualification: Meeting AEC-Q200 indicates suitability for designs with automotive reliability requirements.
• Controlled leakage and loss: Specified leakage current (740 µA) and tan δ (0.20) support predictable DC behavior and low dissipation in filtered circuits.
• Production-ready supply: Part is in mass production and available in bulk or bag packing for standard assembly and procurement workflows.
