UPS2E471MRD

The UPS2E471MRD is a miniature, low‑impedance aluminum electrolytic capacitor designed for radial‑lead through‑hole applications. It is built for general‑purpose use and specifically suited for switching power supplies where compact size and reliable ripple handling are required.

Key electrical characteristics include 470 µF capacitance at a 250 V rating, polarized radial‑can packaging, and a wide operating temperature range suitable for industrial electronics. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 470 µF nominal capacitance with a 250 V rated voltage and a capacitance tolerance of ±20%.
• Low‑impedance design — Engineered for low impedance to support ripple current handling in switching power supply environments; ripple current specs include 1.35 A at 120 Hz and 1.552 A at 10 kHz.
• Compact radial package — Radial, can package with radial lead mounting and a lead spacing of 12.5 mm (1.25 cm) for easy through‑hole assembly.
• Wide operating temperature — Rated for operation from −40 °C to +105 °C to accommodate demanding thermal conditions.
• Durability at elevated temperature — Specified lifetime of 3000 hours at 105 °C under rated conditions, supporting extended service life in high‑temperature applications.
• Polarized construction — Standard polarized electrolytic capacitor for DC filtering and energy storage applications.
• RoHS compliance — Manufactured to meet RoHS directive requirements for environmental compliance.
• Compact footprint — Physical size L: 5 × D: 2.5 cm for space‑constrained PCB or chassis designs.

Typical Applications

• Switching Power Supplies — Bulk filtering and ripple suppression in switch‑mode power converters where low impedance and reliable ripple current capability are needed.
• General‑Purpose Power Electronics — DC link and smoothing applications across industrial and commercial power designs.
• Through‑Hole PCB Designs — Radial‑lead package suited for traditional through‑hole assembly and retrofit/upgradable modules.

Unique Advantages

• Compact, space‑saving form factor — Miniature radial can with a small footprint enables denser power module layouts without sacrificing capacitance.
• Measurable ripple capability — Specified ripple current at both low and high frequencies (1.35 A at 120 Hz; 1.552 A at 10 kHz) provides designers concrete limits for thermal and ripple budgeting.
• Wide temperature endurance — Operation to 105 °C and a 3000‑hour rated lifetime at that temperature help ensure reliable performance in high‑temperature environments.
• Polarized radial mounting — Simple through‑hole installation and reliable mechanical retention for power boards and modules.
• Regulatory compliance — RoHS‑compliant construction supports designs that require restricted‑substance conformance.
• Clear, verifiable specifications — Key parameters such as capacitance, voltage, tolerance, ripple current, operating temperature, and lifetime are provided for accurate design calculations.
