LGU1C183MELB

The LGU1C183MELB is an aluminum electrolytic capacitor in a radial, snap‑in can package designed for general-purpose power applications. It is specified for operation from −40°C to 105°C and delivers 18 mF at a rated voltage of 16 V with polarized terminals and snap‑in mounting for secure board retention.

Engineered for sustained high-temperature operation, this part withstands 3000 hours of rated ripple current at 105°C and is RoHS‑compliant, making it suitable for industrial and commercial electronic power systems where long endurance at elevated temperature and reliable ripple handling are required.

Key Features

• Capacitance & Voltage: 18 mF nominal capacitance at a rated voltage of 16 V, with a tolerance of −20% to +20% (measured at 120 Hz, 20°C).
• High‑temperature Endurance: Endurance rating of 3000 hours at 105°C under DC bias plus rated ripple current; after endurance test, capacitance change remains within ±20% and leakage current meets specified limits.
• Ripple Current Capability: Rated ripple current of 3 A at 120 Hz and 3.45 A at 50 kHz, with frequency coefficients provided for higher frequency operation.
• Wide Operating Temperature Range: Specified for −40°C to +105°C for the 16 V series, enabling operation across typical industrial and commercial temperature profiles.
• Mounting & Package: Radial, can – snap‑in package designed for snap‑in PCB mounting; polarized terminal configuration for DC power applications.
• Regulatory Compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply smoothing: Bulk capacitance for DC filtering and smoothing in low‑voltage power rails and supply modules.
• Power conditioning and hold‑up: Energy storage to support short‑term voltage hold‑up and transient absorption in commercial and industrial electronics.
• Industrial control equipment: General-purpose decoupling and filtering where elevated ambient temperatures and sustained ripple are present.

Unique Advantages

• Verified high-temperature life: 3000‑hour endurance at 105°C provides measurable durability for designs exposed to sustained thermal stress.
• Demonstrated ripple handling: Rated ripple currents at both low (120 Hz) and higher (50 kHz) frequencies—3 A and 3.45 A respectively—help ensure stable performance under AC stress.
• Compact snap‑in form factor: Radial can with snap‑in terminals simplifies PCB retention and mechanical mounting for higher-current applications.
• Wide temperature capability: −40°C to +105°C rating supports a broad range of ambient conditions typical of commercial and industrial installations.
• RoHS compliant: Meets current RoHS requirements, supporting regulatory needs for commercial product designs.
