UCA2D101MHD

The UCA2D101MHD is a miniature aluminum electrolytic capacitor in a radial can package, engineered for high ripple current and long operational life. Manufactured by Nichicon as part of the UCA series, it delivers 100 µF at a rated voltage of 200 V with a compact 16 mm × 25 mm footprint and 7.5 mm lead spacing.

Designed for general‑purpose power electronics, the UCA2D101MHD is suited to applications such as power supplies and ballasts where high ripple handling, elevated operating temperature capability, and long endurance are required.

Key Features

• Capacitance & Voltage: 100 µF rated capacitance at 200 V to support energy storage and filtering in medium‑voltage circuits.
• High ripple current capability: Rated ripple current up to 1.28 A at 100 kHz (1280 mA) and 640 mA at 120 Hz, enabling robust performance under high AC stress.
• Long operational life: Load life of 12000 hours at 105°C, designed for extended service in demanding thermal environments.
• Thermal range: Operating temperature from –25°C to +105°C to accommodate a wide range of ambient conditions.
• Electrical characteristics: Tangent of loss angle (tan δ) 0.15 (max) and leakage current 900 µA (per rated value), providing predictable electrical behavior.
• Mechanical & package: Radial lead can with 16 mm diameter × 25 mm length and 7.5 mm lead spacing for easy through‑hole mounting.
• Compliance: RoHS compliant.

Typical Applications

• Power supplies: Bulk filtering and smoothing in power supply rails where 200 V rating and high ripple handling are required.
• Ballasts: AC ripple management and energy buffering in ballast circuits, leveraging the capacitor’s high ripple current capability.
• General‑purpose industrial electronics: Filtering and decoupling in compact, through‑hole assemblies needing long life at elevated temperatures.

Unique Advantages

• High ripple endurance: 1.28 A at 100 kHz and 640 mA at 120 Hz lets designers reduce series capacitance or parallel component count while handling significant AC stress.
• Extended high‑temperature life: Rated for 12000 hours at 105°C, providing predictable longevity in thermally demanding installations.
• Compact radial footprint: 16 mm × 25 mm can and 7.5 mm lead spacing enable space‑efficient through‑hole designs without sacrificing performance.
• Clear electrical specifications: 0.15 tan δ and a quantified leakage current (900 µA) allow accurate modeling of losses and standby behavior.
• Wide operating temperature: –25°C to +105°C supports deployment across diverse ambient conditions.
• RoHS compliance: Meets environmental restriction requirements for lead‑free manufacturing processes.
