UPJ1A182MHD

The UPJ1A182MHD is an aluminum electrolytic capacitor from Nichicon's UPJ series, configured as a radial-lead can for through-hole mounting. It delivers 1.8 mF capacitance at 10 V in a compact φ12.5 × 20 mm package with 5 mm lead spacing, intended for general-purpose power applications.

Designed for low impedance and high reliability, this part supports switching power supply and power-filtering roles while offering a wide operating temperature range and long load life for demanding thermal environments.

Key Features

• High capacitance, low-voltage rating — 1.8 mF capacitance at a 10 V rating provides bulk energy storage for low-voltage power rails and smoothing applications.
• Low impedance — UPJ series specification calls out low impedance behavior, making this capacitor suited to switching power supplies and high ripple environments.
• Long life at elevated temperature — Rated for 5000 hours at 105°C, enabling extended operation under sustained thermal stress.
• Operating temperature range — −55°C to 105°C supports use across a wide range of ambient and internal board temperatures.
• Loss and leakage characteristics — Specified tan δ of 0.19 and a leakage current of 540 µA provide predictable electrical behavior for design calculations.
• Ripple current capability — Supports 1.188 A at 120 Hz and 1.32 A at 200 kHz, allowing effective handling of both low- and high-frequency ripple from switching converters.
• Package and mounting — Radial, can-style package with 5 mm lead spacing and bulk/no terminal forming option for mass production assembly processes.
• RoHS compliant — Conforms to RoHS requirements as noted for the UPJ series.
• Capacitance tolerance and polarization — ±20% tolerance at 120 Hz, 20°C, and polarized construction for correct circuit placement.

Typical Applications

• Switching power supplies — Provides bulk filtering and energy storage to stabilize low-voltage outputs and absorb switching ripple.
• DC–DC converters — Supports input/output smoothing where compact, high-capacitance components are required at low voltage.
• General-purpose power electronics — Suitable for smoothing, decoupling, and energy storage in industrial and consumer power circuits.

Unique Advantages

• Compact high-capacitance solution: 1.8 mF in a φ12.5 × 20 mm can reduces board area for bulk storage compared with multiple smaller capacitors.
• Designed for ripple handling: Specified ripple current values at both 120 Hz and 200 kHz support a range of power-conversion frequencies.
• Thermal endurance: 5000 hours at 105°C gives designers a measurable reliability parameter for high-temperature applications.
• Predictable electrical behavior: Specified tan δ and leakage current figures allow accurate design margining and thermal/ripple budgeting.
• Through-hole robustness: Radial lead, can-style package simplifies assembly and mechanical retention for boards exposed to vibration or handling.
• Regulatory compliance: RoHS conformity supports use in designs requiring restricted-substance compliance.
