UCYW6100MPD

The UCYW6100MPD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UCY series designed for high ripple current and long-life operation. It is optimized for power electronics where compact size, high voltage handling and extended endurance at elevated temperature are required.

Typical use cases include power supply filtering and ballast circuitry, with AEC‑Q200 qualification and RoHS compliance supporting demanding applications including automotive power systems.

Key Features

• Capacitance & Voltage: 10 µF nominal capacitance rated for 420 V DC with ±20% tolerance (measured at 120 Hz, 20°C).
• High ripple capability: Specified ripple current of 135 mA at 120 Hz and 270 mA at 100 kHz; frequency coefficients for rated ripple current increase up to 2.00 at ≥100 kHz.
• Extended high-temperature life: Designed to withstand load life of 10,000 to 12,000 hours at +105°C under specified test conditions.
• Automotive-grade qualification: AEC‑Q200 qualified for applications requiring automotive reliability standards.
• Wide operating range: Rated for operation from −40°C to +105°C.
• Compact radial can package: Radial lead construction with 5 mm lead spacing and compact footprint (approx. L: 2 cm × D: 1 cm).
• Leakage and dissipation specifications: Leakage current limited to ≤0.04CV+100 µA (after 1 minute at 20°C); tangent of loss angle (tan δ) at 420 V is specified up to 0.24 (120 Hz, 20°C).
• Environmental compliance: RoHS directive compliant.

Typical Applications

• Power supplies and converters: Bulk and smoothing capacitor for high-voltage DC rails where high ripple current and compact size are required.
• Ballasts and lighting drivers: Suited for ballast circuitry referenced in the product description, providing reliable ripple handling and long life at elevated temperatures.
• Automotive power electronics: Suitable for in-vehicle power subsystems and control modules where AEC‑Q200 qualification and high-temperature endurance are required.

Unique Advantages

• High ripple tolerance: Measurable ripple ratings at both low and high frequencies reduce the need for parallel components in many designs.
• Long life at elevated temperature: 10,000–12,000 hour load-life rating at +105°C provides predictable service life in harsh thermal environments.
• AEC‑Q200 qualification: Provides a documented qualification path for designs targeting automotive reliability requirements.
• Small footprint radial package: Compact can and 5 mm lead spacing enable lower board area and straightforward through-hole mounting for robust mechanical retention.
• Predictable electrical behavior: Defined leakage current formula and tan δ limits give engineers measurable parameters for reliability and thermal budgeting.
• RoHS compliance: Meets environmental directive requirements for restricted substances.
