UPJ1K181MHD

The UPJ1K181MHD from Nichicon is a low-impedance aluminum electrolytic capacitor in a radial can package, specified at 180 µF and 80 V with polarized leads. It is designed for switching power supplies and general-purpose power filtering where stable capacitance, high ripple handling and long life at elevated temperatures are required.

Packaged in a φ12.5 × 25 mm can with 5 mm lead spacing, this capacitor combines compact size with industry-oriented electrical characteristics to support power electronics, industrial and consumer applications that require reliable DC smoothing and decoupling.

Key Features

• Capacitance & Voltage: 180 µF rated capacitance at 80 V suitable for medium-voltage filtering and energy storage in power rails.
• Low Impedance Design: Engineered for low impedance to improve ripple performance and reduce voltage drop under AC ripple conditions.
• High Temperature Endurance: Rated operating temperature from −55 °C to +105 °C with a load life of 5000 hours at 105 °C.
• Ripple Current Capability: Specified ripple current of 280.8 mA at 120 Hz and 520 mA at 200 kHz for effective AC ripple handling across low and high frequencies.
• Radial Lead Can Package: φ12.5 × 25 mm can with 5 mm lead spacing and radial lead mounting for through-hole board assembly and robust mechanical retention.
• Polarized Construction & Tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• Environmental Compliance: RoHS compliant material and manufacturing.

Typical Applications

• Switching Power Supplies: Bulk smoothing and output filtering to stabilize DC rails and reduce ripple in SMPS designs.
• Industrial Power Electronics: Decoupling and energy buffering in power converters and motor drive control circuits operating at elevated temperatures.
• Consumer Power Modules: Line-side and intermediate bus filtering where compact, through-hole electrolytics are preferred for serviceability and mechanical robustness.

Unique Advantages

• Long High-Temperature Life: 5000 hours at 105 °C supports designs expected to operate under sustained elevated temperatures, reducing replacement frequency.
• Measured Ripple Performance: Explicit ripple current specifications at both 120 Hz and 200 kHz help designers size capacitors for both transformer- and switching-frequency ripple.
• Compact Radial Can: φ12.5 × 25 mm footprint with 5 mm lead spacing balances board space with capacitance, simplifying layout for through-hole assemblies.
• Low-Impedance Behavior: Designed to minimize impedance across useful frequency ranges, improving transient response and filtering effectiveness.
• RoHS Compliance: Conforms to RoHS requirements, simplifying regulatory considerations for end products.
