UPTW6470MHD

The UPTW6470MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPT series. It is a polarized, radial-lead, can-type capacitor designed for general-purpose and high-ripple DC applications requiring a 420 V rated voltage and 47 µF capacitance.

Built for long life and elevated ripple performance, this part is suited to applications such as lighting ballasts, high-voltage power supplies and industrial DC filtering where a compact, high-voltage electrolytic with proven endurance is required.

Key Features

• High Rated Voltage: 420 V rating for high-voltage DC circuits and filtering.
• Capacitance & Tolerance: 47 µF with ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Capability: Rated ripple current of 360 mA at 120 Hz and 576 mA at 10 kHz, supporting high-ripple and ballast-style applications.
• Long Life Endurance: Designed for 5000 hours at 105°C under DC bias plus rated ripple current, meeting endurance limits for capacitance, tan δ and leakage after recovery to 20°C.
• Thermal Range: Operating temperature range of −40°C to +105°C for broad environmental compatibility.
• Compact Radial Package: Radial lead, can-style package with 5 mm lead spacing and physical size L: 4 × D: 1.25 cm for space-constrained PCB layouts.
• Low Leakage Specified: Leakage current defined per datasheet as not more than 0.06CV + 10 µA after 2 minutes’ application of rated voltage at 20°C.
• RoHS Compliant: Meets RoHS environmental requirements.
• Loss Angle (tan δ): Specified maximum tan δ of 0.20 at the 420 V rating.

Typical Applications

• Lighting Ballasts: Suited for ballast circuits where high ripple current handling is required.
• High‑Voltage Power Supplies: DC filtering and energy storage in SMPS front-ends and high-voltage rails.
• Industrial Equipment: High-voltage filtering and smoothing in industrial control and power electronics.
• General-Purpose Electronics: Compact radial solution for circuits requiring 420 V rated capacitance with long-term endurance.

Unique Advantages

• High-Voltage Capability: 420 V rating enables use in many high-voltage DC applications without parallel parts.
• Designed for High Ripple: Measured ripple ratings (360 mA at 120 Hz, 576 mA at 10 kHz) reduce thermal stress in ripple-intensive circuits.
• Long-Term Reliability: 5000 hours endurance at 105°C under rated conditions supports extended service life in elevated-temperature environments.
• Compact Radial Form Factor: Small L × D footprint with 5 mm lead spacing simplifies layout in space-constrained designs.
• Measured Electrical Limits: Clear specifications for leakage current and tan δ provide predictable performance for engineering validation.
• RoHS Compliance: Conforms to RoHS for environmentally constrained product designs.
