UTF2W121MND

The UTF2W121MND is a high-voltage, radial-lead aluminum electrolytic capacitor designed for demanding power-electronic environments. It combines a 120 µF capacitance with a 450 V rating, high ripple-handling capability and a long load life to support high-voltage DC circuits.

Targeted at automotive power applications, the UTF2W121MND delivers high ripple current, AEC-Q200 qualification, and extended endurance at elevated temperatures, making it suitable for engine-room and on-board power systems where durability and consistent performance matter.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 450 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current — Rated ripple current of 1.36 A rms at 120 Hz and 2.176 A rms at 100 kHz to minimize temperature rise under AC ripple conditions.
• Low Leakage & Controlled Loss — Leakage current specified at 2,260 µA after 1 minute (20°C) and 1,105 µA after 5 minutes (20°C); tan δ max 0.20 at rated voltage.
• Extended Load Life — 5,000 hours lifetime at 105°C under DC bias plus rated ripple, meeting endurance requirements after high-temperature operation.
• Automotive-Ready Qualification — AEC-Q200 qualified and described in the datasheet as suitable for automotive applications (for example, on-board chargers).
• Robust Temperature Range — Operates from −40°C to +105°C to cover typical automotive and harsh-environment operating conditions.
• Radial Can Package — φ18 × 36 mm can with 7.5 mm lead spacing, polarized radial-lead format for through-hole power assemblies; supplied in bulk for volume production.
• Standards Compliance — RoHS compliant, supporting regulatory requirements for restricted substances.

Typical Applications

• Automotive On-board Chargers — High-voltage, high-ripple capability suits DC link and smoothing functions in EV/HEV on-board charger designs.
• Automotive Power Electronics — Designed for automotive power modules such as DC-DC converters and other vehicle high-voltage subsystems where AEC-Q200 qualification is required.
• High-Voltage DC Link Circuits — Useful in high-voltage smoothing and energy-storage roles within power conversion stacks that require sustained ripple handling and long life at elevated temperature.

Unique Advantages

• High ripple tolerance: Higher rated ripple currents (1.36 A at 120 Hz, 2.176 A at 100 kHz) reduce self-heating and extend run-time stability under AC-stressed conditions.
• Long endurance at elevated temperature: 5,000 hours at 105°C under rated bias ensures predictable lifetime for demanding applications.
• Automotive qualification: AEC-Q200 rating provides confidence for use in vehicle electrical systems and related qualification programs.
• Compact high-voltage packaging: φ18 × 36 mm radial can delivers 120 µF at 450 V in a through-hole form factor optimized for high-voltage board-level implementations.
• Tight manufacturing readiness: Supplied in bulk and listed as mass production status for volume deployment and supply continuity.
• Regulatory compliance: RoHS compliant to support environmentally restricted designs.
