UPS2E221MRD

The UPS2E221MRD is a miniature, low‑impedance aluminum electrolytic capacitor designed for radial‑lead through‑hole mounting. It provides 220 µF capacitance at a 250 V rated voltage and is polarization‑type for general-purpose power circuits.

Targeted at switching power supplies and general-purpose electronic designs, this Nichicon UPS series part delivers compact bulk storage and smoothing with defined ripple current ratings, wide operating temperature range, and RoHS compliance.

Key Features

• Capacitance and Voltage: 220 µF nominal capacitance with a 250 V rated voltage, suitable for bulk energy storage and smoothing in higher‑voltage power circuits.
• Low‑Impedance Construction: Engineered for low effective series impedance to support higher ripple currents—specified at 525 mA (120 Hz) and 840 mA (10 kHz).
• Wide Operating Temperature: Rated for operation from −40 °C to 105 °C to support elevated ambient and board temperatures.
• Endurance at High Temperature: Lifetime specified as 3000 hours at 105 °C under rated conditions, providing predictable performance in long‑life applications.
• Compact Radial Can Package: Radial lead, can‑type package with 1.0 cm lead spacing and nominal size L: 4 × D: 2 cm for straightforward through‑hole mounting and assembly.
• Polarity and Tolerance: Polarized device with capacitance tolerance of −20% to +20% at 120 Hz, 20 °C.
• RoHS Compliant: Conforms to RoHS directives as specified in the product data.

Typical Applications

• Switching Power Supplies: Bulk smoothing and ripple suppression where low impedance and higher ripple current capability improve power rail stability.
• General‑Purpose Power Filtering: Energy storage and decoupling in industrial and consumer electronic equipment requiring a polarized aluminum electrolytic solution.
• Through‑Hole PCB Designs: Radial lead mounting for robust mechanical retention and easy placement in traditional through‑hole assemblies.
• High‑Temperature Environments: Applications that operate near elevated temperatures benefit from the 105 °C rated endurance and 3000‑hour life at that temperature.

Unique Advantages

• High Voltage Capability: 250 V rating allows use in higher‑voltage DC link and power rail applications without needing parallel capacitors to meet voltage demands.
• Defined Ripple Performance: Published ripple current ratings at 120 Hz and 10 kHz let designers size capacitors to meet thermal and ripple requirements with measurable data.
• Predictable High‑Temperature Life: 3000 hours at 105 °C provides a clear reliability baseline for thermal stress planning and lifetime estimates.
• Compact Footprint: Small radial can dimensions and 1 cm lead spacing reduce board area compared with larger bulk capacitors while keeping through‑hole robustness.
• RoHS Compliance: Meets applicable RoHS directives for regulated markets and streamlined manufacturing compliance.
