UPT2E221MHD

The UPT2E221MHD is an aluminum electrolytic capacitor in a radial-lead can package designed for compact, general-purpose power applications. It delivers 220 µF at 250 V with a polarized configuration and is presented as a miniature-sized, high-ripple, long-life component.

Key attributes include high ripple-current capability, extended endurance at elevated temperature, and RoHS compliance—making it suitable where sustained ripple handling and long-term operation are required.

Key Features

• Capacitance and Voltage — 220 µF rated capacitance at 250 V nominal.
• High ripple-current capability — Rated ripple currents of 830 mA at 120 Hz and 1.328 A at 10 kHz support heavy AC ripple conditions.
• Long endurance at elevated temperature — Specified lifetime of 5000 hours at 105 °C under DC bias plus rated ripple current; after recovery to 20 °C, capacitance remains within ±20% of initial value.
• Leakage current specification — Leakage current not more than 0.06CV + 10 μA after 2 minutes’ application of rated voltage at 20 °C, per datasheet formulation.
• Loss tangent (tan δ) — Maximum tan δ of 0.12 at 250 V (measured at 120 Hz, 20 °C), indicating dissipation characteristics for design consideration.
• Mechanical and mounting — Radial lead, can-style package with 7.5 mm lead spacing for through-hole PCB mounting; size dimensions L: 4 × D: 1.6 cm support compact layouts.
• Temperature range — Operating from −40 °C to +105 °C to match a broad set of environmental conditions.
• Regulatory status — RoHS compliant.

Typical Applications

• Ballast systems — Suited for ballast applications that require sustained ripple handling and long-term stability under AC ripple conditions.
• General-purpose power filtering — Use in power-supply filtering and decoupling where 250 V rating and 220 µF capacitance meet bulk or smoothing requirements.
• Space-constrained high-ripple circuits — Miniature can package and radial lead form factor provide a compact solution for circuits needing elevated ripple performance.

Unique Advantages

• High ripple tolerance: Measured ripple ratings of 830 mA (120 Hz) and 1.328 A (10 kHz) allow reliable operation in high-AC-ripple environments.
• Proven long-life performance: Rated for 5000 hours at 105 °C under DC bias plus rated ripple current, with controlled changes in capacitance and leakage after recovery.
• Compact footprint: L: 4 × D: 1.6 cm radial-can format delivers high capacitance and voltage in a small package for board-space savings.
• Defined electrical behavior: Leakage current and tan δ specifications are provided for predictable circuit design and verification.
• Wide operating temperature range: −40 °C to +105 °C supports deployment across a variety of ambient conditions.
• Regulatory compliance: RoHS status ensures conformity with common environmental restrictions.
