UPW1H470MED

The UPW1H470MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPW series. It is a polarized radial-lead can designed for compact power applications where low impedance and robust thermal performance are required.

With a 47 µF capacitance at 50 V, AEC-Q200 rating, and an operating temperature range of -55 °C to 105 °C, the UPW1H470MED is targeted at automotive and power-supply use cases that demand stable ripple handling and proven reliability in harsh environments.

Key Features

• Form Factor — Radial can, miniature: Radial lead mounting with package dimensions L: 1.1 × D: 0.63 cm and 2.5 mm lead spacing for compact through-hole designs.
• Electrical rating — 47 µF, 50 V: 47 µF capacitance with ±20% tolerance and polarized construction for DC decoupling and bulk filtering.
• Temperature and lifetime: Rated for -55 °C to 105 °C and specified lifetime of 2000 hours at 105 °C.
• AEC-Q200 qualification: Designed and rated for automotive-grade reliability (AEC-Q200).
• Low-impedance design and ripple handling: Series-level design optimized for switching power supplies; rated ripple current 90 mA at 120 Hz and 300 mA at 10 kHz.
• Leakage and loss characteristics: Leakage current limited to 0.03 × C × V (µA) after one minute at 20 °C; tangent of loss angle (tan δ) maximum for 50 V is 0.10 at 120 Hz, 20 °C.
• Safety feature — pressure relief vent: Radial lead variants include a pressure relief vent for improved safety in end-use applications.

Typical Applications

• Automotive electronics: AEC-Q200 rating and wide temperature range make this capacitor suitable for automotive power modules and control electronics requiring reliable decoupling and bulk capacitance.
• Switching power supplies: Low-impedance design and specified ripple current at audio and high frequencies support use on input/output rails of DC–DC converters and SMPS designs.
• Industrial power systems: Compact radial package and robust thermal performance are useful for distributed filtering in industrial power supplies and control equipment.

Unique Advantages

• Compact footprint for space-constrained designs: Small L × D (1.1 × 0.63 cm) and 2.5 mm lead spacing enable dense component placement in through-hole assemblies.
• AEC-Q200 qualification: Provides a documented reliability baseline for automotive and other demanding environments.
• Verified ripple performance across frequencies: Rated ripple current values (90 mA at 120 Hz; 300 mA at 10 kHz) help designers size capacitors for both low- and high-frequency ripple conditions.
• Wide operating temperature range: -55 °C to 105 °C supports operation in harsh thermal conditions typical of automotive and industrial applications.
• Leakage and loss specifications provided: Clear leakage current formula and tan δ limits allow accurate modeling of leakage and dissipation in circuit-level simulations.
