UPT2E471MRD6

The UPT2E471MRD6 is a miniature radial-lead aluminum electrolytic capacitor designed for high ripple-current and long-life applications. It delivers 470 µF at 250 V in a compact φ25 × 40 mm can with 12.5 mm lead spacing.

Engineered for general-purpose and ballast applications, this RoHS-compliant unit offers a wide operating temperature range from −40°C to +105°C and an endurance rating of 5000 hours at 105°C, making it suitable for demanding power-conditioning environments.

Key Features

• Rated Capacitance & Voltage — 470 µF capacitance at a rated voltage of 250 V, with a capacitance tolerance of ±20% (120 Hz, 20°C).
• High Ripple Current — Ripple handling of 1.45 A at 120 Hz (105°C) and 2.32 A at 10 kHz, supporting high AC stress in power circuits.
• Long Endurance — Rated for 5000 hours of service at 105°C under DC bias plus rated ripple current, with capacitance change within ±20% after endurance testing.
• Temperature Range — Operates from −40°C to +105°C for broad environmental compatibility.
• Electrical Losses & Leakage — Maximum tan δ of 0.12 at 120 Hz (20°C) and a specified leakage current value of 7060 µA as provided for this part.
• Package & Mounting — Radial-lead, can-style package (φ25 × 40 mm) with 12.5 mm lead spacing; available in bulk/bag packing.
• Regulatory — Compliant with RoHS requirements.

Typical Applications

• Ballast Circuits — Suited for ballast applications where high ripple current capability in a compact footprint is required.
• General-Purpose Power Supply Filtering — Provides bulk capacitance and ripple handling for AC/DC and DC/DC stages in general-purpose designs.
• Power Conditioning — Useful where sustained operation at elevated temperature and continuous ripple stress are expected.

Unique Advantages

• Compact high-capacitance package: 470 µF in a φ25 × 40 mm can delivers substantial capacitance while minimizing board area.
• Designed for ripple stress: Specified ripple currents at 120 Hz and 10 kHz that support AC-loaded power circuits and ballast use cases.
• Long operational life: 5000 hours at 105°C under DC bias plus rated ripple current reduces maintenance and replacement frequency in deployed systems.
• Wide temperature capability: −40°C to +105°C rating accommodates harsh thermal environments common to power electronics.
• RoHS compliance: Meets environmental directive requirements for lead-free manufacturing processes.
