UPJ2E100MHD

The UPJ2E100MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPJ series, designed for low-impedance power applications. This 100 µF, 25 V polarized capacitor delivers stable decoupling and ripple handling in compact radial-can packaging for general-purpose electronic designs.

Built for reliability under elevated temperatures, the UPJ2E100MHD is specified for 5,000 hours of endurance at 105°C and is well suited to switching power supplies and other power-rail applications that require low loss and controlled leakage.

Key Features

• Capacitance & Voltage: 100 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of ±20% (measured at 20°C, 120 Hz).
• Low Dissipation Factor: tan δ = 0.14 (measured at 20°C, 120 Hz) to minimize loss in AC and ripple environments.
• Ripple Current Capability: Low-frequency ripple current 98 mA at 120 Hz and high-frequency ripple current 156.8 mA at 200 kHz to support switching regulator filtering and decoupling.
• Leakage Current: Specified leakage current of 200 µA after rated voltage application.
• Endurance / Reliability: Rated for 5000 hours life at 105°C under specified load conditions, supporting long-term operation in elevated-temperature environments.
• Operating Temperature: −40°C to +105°C to cover a wide range of commercial and industrial ambient conditions.
• Package & Mechanical: Radial lead can, size φ12.5 × 20 mm (L), lead spacing 5 mm with 0.5 mm tolerance; available in Bulk (no terminal forming) or Bag packing.
• Environmental Compliance: RoHS compliant.
• Product Status: End Of Life.

Typical Applications

• Switching Power Supplies: Low impedance and defined ripple current ratings make this capacitor suitable for output filtering and decoupling in switching regulators.
• DC-DC Converters: Use for stabilizing power rails and reducing voltage ripple in compact converter designs.
• General Purpose Power Rails: Bulk decoupling and smoothing on consumer and industrial PCBs where a radial-lead can fits the board layout.

Unique Advantages

• Low-impedance design: Tangent of loss angle (tan δ = 0.14) and series UPJ characteristics help reduce AC loss in ripple-heavy circuits.
• High-temperature endurance: 5000-hour rating at 105°C provides predictable lifetime performance under continuous thermal stress.
• Measured ripple performance: Specified ripple currents at both low and high frequencies allow designers to size components against actual switching and line-frequency stressors.
• Compact radial-can footprint: φ12.5 × 20 mm package with 5 mm lead spacing provides space-efficient power decoupling for through-hole assemblies.
• Controlled leakage: Defined leakage current helps ensure predictable bias behavior in standby and low-current conditions.
