UPT2E221MHD6

The UPT2E221MHD6 is a miniature radial-lead aluminum electrolytic capacitor designed for general-purpose power electronics and ballast applications. It combines a compact radial can package with high ripple-current capability and a long rated lifetime for reliable smoothing and filtering in compact assemblies.

Key attributes include a 220 µF capacitance at 250 V, wide operating temperature range from −40°C to +105°C, and RoHS compliance, making it suitable for designs that require durable, high-ripple capacitors in a small form factor.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 250 V for bulk energy storage and filtering in power circuits.
• High ripple-current capability — Rated ripple current of 830 mA at 120 Hz and 1.328 A at 10 kHz, supporting demanding AC ripple conditions in ballast and power-supply applications.
• Long life at elevated temperature — Endurance specified as 5000 hours at 105°C under D.C. bias plus rated ripple current, with defined limits for capacitance change, tan δ and leakage current after test.
• Wide temperature range — Operates from −40°C to +105°C, enabling use across a broad set of environmental conditions.
• Compact radial package — Radial can construction with 7.5 mm lead spacing and package dimensions L: 3.55 × D: 1.8 cm for space-constrained PCBs.
• Polarized design — Standard polarized aluminum electrolytic construction for DC smoothing and bulk decoupling.
• RoHS compliant — Meets RoHS directive requirements included in the product data.

Typical Applications

• Ballasts and lighting drivers — Handles the ripple and DC bias typical in ballast circuits, as noted in the series specification.
• Power supply smoothing — Bulk filtering and smoothing in general-purpose power supplies where compact size and high ripple tolerance are required.
• General-purpose power electronics — Energy storage and decoupling in applications that benefit from long life at elevated temperatures and reliable leakage performance.

Unique Advantages

• High ripple tolerance: Measured ripple current ratings at both 120 Hz and 10 kHz demonstrate suitability for applications with significant AC ripple content.
• Long-term reliability under stress: 5000 hours endurance at 105°C with defined limits for capacitance, tan δ and leakage current supports predictable long-term performance.
• Compact footprint: Small radial can dimensions (L: 3.55 × D: 1.8 cm) and 7.5 mm lead spacing help reduce PCB area in compact designs.
• Wide operating temperature: −40°C to +105°C rating enables use across a broad range of ambient conditions without derating the capacitor’s fundamental specifications.
• Regulatory compliance: RoHS-compliant construction simplifies material compliance in end products.
