UPJ1E182MHD

The UPJ1E182MHD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series, supplied in a radial lead can. It delivers 1.8 mF capacitance at a 25 V rating with low impedance characteristics targeted for power applications such as switching power supplies and general-purpose power smoothing.

Key value propositions include robust ripple-current handling, extended high-temperature life, and a compact φ12.5 × 35.5 mm package with 5.0 mm lead spacing for through-hole radial mounting.

Key Features

• Capacitance & Voltage: 1.8 mF (1800 µF) rated at 25 V with capacitance tolerance of -20% to +20%.
• Low Impedance Design: UPJ series construction optimized for low impedance, making it suitable for switching power supply filtering and fast transient energy requirements.
• High Ripple‑Current Capability: Handles 1.764 A at 120 Hz (low frequency) and 1.96 A at 200 kHz (high frequency) for effective smoothing under dynamic loads.
• Loss Characteristics: Tangent of loss angle (tan δ) = 0.14 measured at 20°C, 120 Hz for the 25 V rating, supporting efficient AC performance.
• Long Life Endurance: Rated for 5000 hours at +105°C, providing extended service life under high-temperature load conditions.
• Operating Temperature Range: -55°C to +105°C for wide thermal operating margins in demanding environments.
• Compact Radial Package: Can dimensions φ12.5 × 35.5 mm, radial lead mounting with 5.0 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Leakage Current: Specified leakage current of 1350 µA.
• RoHS Compliant: Conforms to RoHS directive per product information.

Typical Applications

• Switching Power Supplies: Bulk energy storage and output smoothing where low impedance and high ripple-current capability reduce output ripple and improve regulation.
• Power Rail Decoupling: Local energy reservoir on DC power rails to support transient loads and maintain stable voltage under dynamic conditions.
• Industrial Power Modules: Filtering and smoothing in industrial power supplies and converters that require long high-temperature endurance.

Unique Advantages

• Robust Ripple Handling: Rated ripple currents at both low and high frequencies (1.764 A @120 Hz and 1.96 A @200 kHz) support rigorous switching environments.
• Extended High‑Temperature Life: 5000 hours endurance at +105°C gives predictable aging and dependable long-term performance in elevated temperatures.
• Compact, Serviceable Package: φ12.5 × 35.5 mm radial can with standard 5.0 mm lead spacing enables easy through-hole mounting and replacement in space-constrained boards.
• Low Dissipation Factor: tan δ = 0.14 at 20°C, 120 Hz (25 V) contributes to lower internal heating and efficient AC behavior.
• Clear Specification Set: Explicit leakage current and tolerance figures simplify design margin calculations and reliability planning.
• Regulatory Compliance: RoHS status supports environmentally constrained designs and procurement requirements.
