UPT2D821MRD

The UPT2D821MRD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPT series, designed for miniature, high-ripple applications that require extended operational life. This polarized, can-style capacitor is intended for general-purpose power electronics where high ripple handling and long-term stability at elevated temperatures are required.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance rated at 200 V DC, suitable for bulk energy storage and smoothing in mid-voltage circuits.
• High Ripple Current: Rated ripple current of 1.6 A at 120 Hz and 2.56 A at 10 kHz, enabling reliable operation under AC ripple loads.
• Compact Radial-Can Package: Radial lead, can-style package with lead spacing of 1.25 cm and physical size L: 5 × D: 2.5 cm for space-conscious board designs.
• Wide Operating Temperature: Specified operating range from –40 °C to +105 °C to support a broad range of environmental conditions.
• Long Life Endurance: Rated for 5000 hours at 105 °C under DC bias plus rated ripple current, demonstrating long-term durability in elevated-temperature applications.
• Leakage Current Specification: Leakage current after 2 minutes at 20 °C is specified as not more than 0.06CV + 10 (µA), providing a clear metric for insulation performance.
• Tolerance & Polarization: Capacitance tolerance of ±20% and polarized construction for correct orientation in DC circuits.
• RoHS Compliant: Manufactured in compliance with RoHS directives.

Typical Applications

• Lighting Ballasts: High ripple current capability and long endurance make this capacitor suitable for ballast designs that require sustained AC ripple handling.
• Power Supply Smoothing: Used for bulk filtering and smoothing in power supplies where 200 V rated voltage and high capacitance are required.
• General-Purpose Industrial Electronics: Applicable to a wide range of general-purpose circuits that benefit from a compact radial electrolytic with extended life at elevated temperature.

Unique Advantages

• High ripple tolerance: The specified ripple currents at 120 Hz and 10 kHz reduce the need for additional parallel components in designs with significant AC content.
• Long-duration reliability: Endurance rating of 5000 hours at 105 °C ensures predictable lifetime behavior under continuous high-temperature operation.
• Clear leakage specification: The leakage current formula (0.06CV + 10 µA after 2 minutes at 20 °C) provides a measurable baseline for quality and selection.
• Space-efficient form factor: Compact L: 5 × D: 2.5 cm radial-can package with 1.25 cm lead spacing supports dense PCB layouts while maintaining serviceable leads for through-hole mounting.
• Designed for real-world ripple spectra: Series frequency coefficients indicate increased allowable ripple at higher frequencies (e.g., coefficient 1.60 at 10 kHz or more), aligning with the part’s rated high-frequency ripple current.
• Regulatory compliance: RoHS compliance simplifies selection for markets that require restricted-substance conformance.
