UPS2D471MRD

The UPS2D471MRD is a miniature, low-impedance aluminum electrolytic capacitor in a radial can package designed for switching power supplies and general-purpose power applications. It combines a 470 µF capacitance with a 200 V rated voltage and polarized radial-lead mounting for straightforward PCB integration.

Engineered for demanding power environments, the part offers specified ripple handling at both low and high frequencies, a wide operating temperature range from −40 °C to 105 °C, a 3,000-hour endurance rating at 105 °C, and RoHS compliance for regulatory compatibility.

Key Features

• Capacitance & Rated Voltage — 470 µF capacitance with a 200 V rated voltage and a tolerance of ±20% (at 120 Hz, 20 °C), suitable for energy storage and smoothing in high-voltage power circuits.
• Low Impedance & Ripple Handling — Specified ripple current of 1.31 A at 120 Hz and 1.506 A at 10 kHz, providing measurable AC endurance for switching power supply filtering and decoupling.
• Wide Temperature & Endurance — Operating temperature range of −40 °C to 105 °C and a lifetime rating of 3,000 hours at 105 °C under rated conditions, supporting sustained performance in elevated-temperature installations.
• Radial Lead Package — Radial, can-style package with radial lead mounting and 10 mm (1 cm) lead spacing for reliable through-hole assembly.
• Compact Dimensions — Physical size L: 5 × D: 2.2 cm, enabling space-conscious board layouts while maintaining required capacitance for power applications.
• Polarized with Low Leakage — Polarized construction; series datasheet specifies leakage current after 1 minute at 20 °C not more than 0.03CV (µA), useful for predicting standby losses in designs.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU,(EU)2015/863), meeting environmental substance restrictions for many commercial and industrial projects.

Typical Applications

• Switching Power Supplies — Provides bulk energy storage and ripple smoothing on high-voltage rails in switched-mode power converters.
• Power Conversion Modules — Used for output filtering and decoupling where compact, high-voltage capacitance is required.
• Industrial Power Equipment — Suitable for general-purpose filtering in industrial control and power distribution assemblies operating up to 105 °C.
• PCB Power Rails — Fits through-hole layouts that require a radial-lead can capacitor with standardized lead spacing and predictable ripple performance.

Unique Advantages

• Measurable Ripple Performance: Explicit ripple current ratings at 120 Hz and 10 kHz allow designers to size capacitors against actual AC stress in switching environments.
• High-Voltage Capability: 200 V rating enables use on higher-voltage rails where lower-voltage electrolytics are unsuitable.
• Endurance at Elevated Temperature: 3,000 hours at 105 °C provides a quantifiable lifetime metric for thermal reliability planning.
• Compact, Through-Hole Form Factor: Radial can and 10 mm lead spacing simplify assembly into conventional through-hole boards while conserving PCB area.
• Predictable Leakage Behavior: Series leakage current specification (0.03CV µA after 1 minute at 20 °C) supports power-budget and standby-loss calculations.
• RoHS Compliance: Conforms to applicable RoHS directives to support regulatory and procurement requirements.
