UPTW6181MRD

The UPTW6181MRD is an aluminum electrolytic capacitor in a radial lead can designed for compact, high-voltage applications. It combines a 180 µF capacitance with a 420 V rated voltage in a miniature package to address applications that require high ripple current handling and extended operational life.

Engineered for general-purpose use and explicitly suited for ballast applications, this part delivers high ripple capability, long-term endurance at elevated temperature, and straightforward radial-lead mounting for through-hole assemblies.

Key Features

• High Voltage Rating: 420 V rated voltage suitable for high-voltage DC circuits.
• 180 µF Capacitance: Provides energy storage and smoothing where mid-range capacitance is required; capacitance tolerance ±20%.
• High Ripple Current: Supports 950 mA at 120 Hz (low frequency) and 1.52 A at 10 kHz (high frequency), enabling robust performance under AC ripple stress.
• Long Life Performance: Endurance rating of 5000 hours at 105°C under DC bias plus rated ripple current, with defined limits on capacitance change, tan δ, and leakage current after test.
• Wide Operating Temperature: Specified for −40°C to +105°C operation.
• Radial Lead Can Package: Compact radial, can-style package with 1 cm lead spacing and a physical footprint of L × D = 5 × 2.2 cm for simple through-hole implementation.
• Low Leakage Current Specified: Leakage current limit given as I ≤ 0.06CV + 10 µA after 2 minutes at 20°C (per datasheet), supporting low-loss DC applications.
• Controlled Dissipation Factor: Specified tan δ limits (up to 0.20 at higher rated voltages) to characterize AC loss behavior.
• RoHS Compliant: Manufactured in compliance with RoHS directives.

Typical Applications

• Ballast applications: Designed for use in ballast circuits where high ripple current capability is required.
• High-voltage DC filtering: 420 V rating and 180 µF capacitance provide smoothing and energy buffering in high-voltage power stages.
• Compact through-hole power modules: Miniature radial can package and 1 cm lead spacing support compact PCB layouts for power electronics assemblies.

Unique Advantages

• High ripple tolerance: Explicit ripple current ratings at both 120 Hz and 10 kHz ensure the device handles common AC stress levels in power and ballast circuits.
• Extended high-temperature life: 5000 hours at 105°C under rated conditions provides predictable long-term performance in elevated-temperature environments.
• Clear electrical limits: Leakage current and tan δ are specified with measurable formulas and maxima, simplifying margin calculation and reliability assessments.
• Compact radial package: Small L × D footprint with radial leads delivers space-efficient through-hole mounting without sacrificing voltage or ripple capability.
• RoHS compliance: Meets environmental directive requirements for restricted substances.
