UPJ2E101MHD

The UPJ2E101MHD is a miniature, high-reliability aluminum electrolytic capacitor in the UPJ series with a radial-lead can package. It delivers 100 µF capacitance at a 250 V rating and is designed for general-purpose electronic power applications.

Engineered for low impedance and sustained operation under load, this radial-lead capacitor is well suited for switching power supplies and other power-filtering roles where ripple handling and long-term endurance matter.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with a tolerance of -20% to +20% measured at 20°C, 120 Hz.
• Rated Voltage & Polarization — 250 V rated voltage; polarized aluminum electrolytic construction for DC power applications.
• Low Impedance Performance — Designed as a low-impedance part suitable for switching power supplies; specified tangent of loss angle (tanδ) = 0.2 at 20°C, 120 Hz.
• Ripple Current Capability — Low-frequency ripple current 345 mA at 120 Hz and high-frequency ripple current 552 mA at 200 kHz, supporting effective smoothing under varying frequencies.
• Leakage Current — Specified leakage current of 1100 µA.
• Reliability & Lifetime — Rated endurance of 5000 hours at 105°C under D.C. bias plus rated ripple current (per UPJ series specification).
• Operating Temperature Range — Rated for -40°C to +105°C.
• Mechanical & Mounting — Radial lead can package, dimensions φ18 × 40 mm length, lead spacing 7.5 mm with ±0.5 mm tolerance; available in bulk or bag packing (no terminal forming).
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Low-impedance construction and rated ripple currents make it suitable for output filtering and smoothing in switching regulators.
• General-Purpose Power Filtering — Use in a range of general-purpose electronic designs requiring polarized DC filtering at 250 V.
• Commercial and Industrial Power Electronics — Endurance at elevated temperature and radial-lead packaging support use in sustained-load power circuits.

Unique Advantages

• High-temperature endurance: 5000 hours rated life at 105°C provides extended service life under continuous load conditions.
• Measured low-loss characteristic: Specified tanδ of 0.2 (20°C, 120 Hz) helps maintain performance in power filtering applications.
• Wide operating temperature range: −40°C to +105°C covers many commercial and industrial environments.
• Frequency-flexible ripple handling: Distinct low- and high-frequency ripple current ratings (345 mA at 120 Hz, 552 mA at 200 kHz) support mixed-frequency power systems.
• Compact radial-lead form factor: φ18 × 40 mm can and 7.5 mm lead spacing simplify through-hole PCB integration for power sections.
• RoHS compliant: Conforms to RoHS requirements for regulated-environment manufacturing.
