UAQ2D151MRD3

The UAQ2D151MRD3 is a radial-lead aluminum electrolytic capacitor offering 150 µF capacitance at a 200 V rating, designed for general-purpose electronic applications. It features a compact φ22 × 20L can with 10 mm lead spacing and polarized radial-lead mounting for through-hole use.

Key performance attributes include high ripple-current capability, a wide operating temperature range from -40°C to +105°C, and a 2000-hour endurance rating at 105°C. Note: this product is End of Life and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance at a 200 V rated voltage with ±20% tolerance for general-purpose circuit use.
• High Ripple Current — Rated ripple currents of 435 mA at 120 Hz (low frequency) and 696 mA at 10 kHz (high frequency) to support demanding AC ripple conditions.
• Endurance at Elevated Temperature — 2000 hours lifetime when subjected to rated DC bias plus rated ripple current at 105°C.
• Wide Temperature Range — Operating range from -40°C to +105°C to accommodate varied environmental conditions.
• Leakage and Loss Characteristics — Specified leakage current of 1300 µA and tan δ up to 0.15 (at 120 Hz, 20°C) for predictable performance metrics.
• Safety Features — Improved safety performance for abnormal over-voltage conditions and a pressure relief vent designed to operate without dangerous flame or dispersion.
• Package & Mounting — Radial can package with φ22 × 20L dimensions and 10 mm lead spacing for straightforward through-hole assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose electronic circuits — Provides bulk capacitance for a wide range of electronic equipment requiring a polarized aluminum electrolytic capacitor.
• Power conversion and filtering — High ripple-current capability and endurance at 105°C suit applications with significant AC ripple or smoothing requirements.
• Industrial and commercial equipment — The wide −40°C to +105°C operating range supports deployment across varied ambient conditions in general-purpose systems.

Unique Advantages

• Measurable ripple performance — Explicit low- and high-frequency ripple current ratings (435 mA @120 Hz; 696 mA @10 kHz) allow designers to size capacitors against documented ripple loads.
• Documented high-temperature endurance — 2000 hours at 105°C under rated conditions gives a clear reliability baseline for thermal-stressed designs.
• Safety-conscious construction — Enhanced protection for abnormal voltages and a pressure relief vent reduce the risk of dangerous failure modes.
• Through-hole form factor — Radial lead, polarized can with 10 mm lead spacing and compact φ22×20L dimensions simplifies PCB layout for through-hole assemblies.
• Regulatory alignment — RoHS compliance supports environmentally regulated product builds.
