UCA2D101MHD6

The UCA2D101MHD6 from Nichicon is a miniature, radial-leaded aluminum electrolytic capacitor designed for high ripple current and long operational life in compact power designs. It is a polarized, through-hole can capacitor in the UCA series, tailored for power-supply filtering and ballast applications.

Key value propositions include a 200 V rated voltage, 100 µF capacitance in a compact radial can, high ripple capability at both low and high frequencies, and demonstrated endurance of 12,000 hours at +105°C.

Key Features

• Capacitance & Voltage: 100 µF rated capacitance at 200 V for energy storage and smoothing in high-voltage circuits.
• Long Life Endurance: Rated for 12,000 hours at +105°C under DC bias plus rated ripple current, supporting extended service life in demanding thermal environments.
• High Ripple Current: Rated ripple current of 590 mA at 120 Hz and 1.18 A at 100 kHz, enabling effective ripple handling across common power frequencies.
• Temperature Range: Operates from −25°C to +105°C to cover a wide range of industrial operating conditions.
• Radial Lead/Package: Radial lead, can package with 7.5 mm lead spacing suited for through-hole power assemblies; polarized design for correct orientation in DC circuits.
• Leakage Current Specification: Leakage current after 1 minute at 20°C is specified as ≤ 0.04CV + 100 µA (where C is µF and V is rated voltage).
• Tolerance & Size: Capacitance tolerance ±20%; compact dimensions L: 20 mm × D: 18 mm for space-constrained layouts.
• Environmental Compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Power Supplies: Bulk smoothing and output filtering in high-voltage DC power supplies where high ripple capability and long life are required.
• Ballasts and Lighting Drives: Energy storage and ripple suppression in electronic ballasts and lamp-driver circuits operating at elevated temperatures.
• Industrial Power Electronics: Filtering and decoupling in converters and inverters where a compact, high-voltage electrolytic is needed.
• General Purpose High-Voltage Circuits: Through-hole implementations requiring polarized capacitance with reliable endurance at +105°C.

Unique Advantages

• Designed for Extended Operation: 12,000-hour life rating at +105°C provides durability for prolonged deployments.
• High-Frequency Ripple Capability: Specified ripple current up to 1.18 A at 100 kHz reduces thermal stress in high-frequency switching environments.
• Compact High-Voltage Solution: 100 µF at 200 V in a small radial can offers high energy density for space-limited PCBs.
• Clear Leakage Specification: Leakage current formula (≤ 0.04CV + 100 µA) enables predictable leakage budgeting in design calculations.
• RoHS Compliance: Meets RoHS directive requirements for lead-free assemblies and regulatory alignment.
