UTF2W131MND

The UTF2W131MND is a radial-lead aluminum electrolytic capacitor designed for high-voltage, high-ripple applications. It delivers 130 µF capacitance at a 450 V rating in a compact φ18×40 mm can with 7.5 mm lead spacing.

Targeted at demanding power electronics and automotive use cases, this part combines high ripple-current capability and extended 5,000-hour endurance at 105°C to support DC link, filtering and energy-buffering functions in harsh environments.

Key Features

• Capacitance & Voltage — 130 µF nominal capacitance with ±20% tolerance and a 450 V rated voltage for high-voltage power systems.
• High Ripple Current — Rated ripple current of 1.41 A at 120 Hz (low frequency) and 2.256 A at 100 kHz (high frequency), enabling sustained AC ripple handling in power converters.
• Endurance & Temperature Range — 5,000 hours load life at 105°C and an operating range from −40°C to +105°C for prolonged operation in elevated-temperature environments.
• Leakage & Loss — Specified leakage current of 2440 µA (after 1 minute at 20°C) and a maximum tan δ of 0.20 at rated voltage, 120 Hz.
• Package & Mounting — Radial lead, can-style package, φ18×40 mm case size with 7.5 mm lead spacing for through-hole assembly and robust mechanical mounting.
• Automotive-Grade Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, supporting automotive and other regulated applications.

Typical Applications

• Automotive On-board Chargers — Bulk and DC-link smoothing where 450 V rating and high ripple endurance are required for reliable charger operation.
• Power Converters & Inverters — Output filtering and energy buffering in high-voltage DC–DC and inverter stages that demand sustained ripple handling.
• Industrial Power Supplies — Bulk capacitance and ripple suppression in industrial rectifiers and power-conditioning modules operating at elevated temperatures.
• Energy Storage & DC Link — Decoupling and energy buffering in systems that require high-voltage capacitance and long thermal life.

Unique Advantages

• High ripple capability: Defined ripple ratings at both low and high frequencies (1.41 A at 120 Hz; 2.256 A at 100 kHz) reduce thermal stress and improve reliability in AC-loaded applications.
• Extended high-temperature life: 5,000 hours rated endurance at 105°C supports long-term operation in elevated ambient conditions.
• AEC-Q200 qualified: Explicit qualification for demanding vehicle and industrial environments simplifies component selection for regulated designs.
• Compact, serviceable packaging: φ18×40 mm radial can with 7.5 mm lead spacing provides a space-efficient through-hole solution for power assemblies.
• Controlled leakage and dissipation: Leakage current and tan δ specifications allow predictable behavior for designs that require tight power-loss control.
• RoHS compliant: Conforms to RoHS requirements for regulatory alignment in global production.
