UPS1J471MHD

The UPS1J471MHD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose power filtering. It is a radial‑lead can type, polarized electrolytic with RoHS compliance.

Key performance attributes include 470 µF capacitance at 63 V, a wide operating temperature range of −55°C to 105°C, low impedance (81 mΩ), and rated ripple current suitable for both low and high frequency filtering. The part is specified for a 3000‑hour lifetime at 105°C.

Key Features

• Capacitance & Voltage — 470 µF rated capacitance at 63 V for bulk energy storage and decoupling in power rails.
• Low Impedance — 81 mΩ impedance (specified) for improved transient response and lower AC loss in power circuits.
• Ripple Current Capability — Rated ripple current of 852 mA at 120 Hz and 1.2 A at 10 kHz to handle both low‑ and high‑frequency ripple components.
• Wide Temperature Range — Operates from −55°C to 105°C to support demanding thermal environments.
• Long High‑Temperature Lifetime — Specified endurance of 3000 hours at 105°C under rated conditions.
• Compact Radial Package — Radial can with lead spacing of 5 mm and size dimension L: 2.5 × D: 1.25 cm for space‑constrained board layouts.
• Polarized Construction — Polarized electrolytic design for common DC bulk and smoothing applications.
• RoHS Compliant — Meets the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing to stabilize DC rails and reduce ripple in power converters.
• DC‑DC Converters and Regulators — Input and output decoupling where compact size and high ripple capability are required.
• Industrial and Consumer Power Electronics — General‑purpose energy storage and filtering in compact, temperature‑variable systems.
• General Purpose Power Filtering — Applications needing polarized electrolytic capacitance with long high‑temperature endurance.

Unique Advantages

• Improved Power Stability: Low impedance (81 mΩ) reduces voltage drop under load and improves transient response in power rails.
• Frequency Versatility: Ripple current ratings specified for both 120 Hz (852 mA) and 10 kHz (1.2 A) make the part suitable for mixed‑frequency ripple environments.
• Compact Footprint: Radial can and small dimensions (L: 2.5 × D: 1.25 cm) allow integration into tight board layouts without sacrificing capacitance.
• Wide Thermal Range: −55°C to 105°C operating range supports deployment across broad ambient and internal temperature conditions.
• Durability at Elevated Temperature: Rated for 3000 hours at 105°C, providing predictable life under sustained high‑temperature operation.
• Regulatory Compliance: RoHS conformity simplifies use in regions requiring restricted substance compliance.
