LGU1H332MELA

The LGU1H332MELA from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGU series designed for general‑purpose applications. It delivers 3.3 mF (3300 µF) capacitance at a 50 V rating with snap‑in mounting in a φ25 × 30 mm can.

Engineered for sustained performance at elevated temperature, the part is specified for operation from −40 °C to +105 °C and an endurance of 3000 hours at 105 °C, making it suitable where long‑term ripple endurance and bulk capacitance are required.

Key Features

• Capacitance & Voltage: 3.3 mF (3300 µF) rated at 50 V with ±20% tolerance (120 Hz, 20 °C).
• High‑temperature Endurance: Rated life of 3000 hours at 105 °C under DC bias plus rated ripple current; meets the LGU series endurance specification.
• Ripple Current Performance: Low‑frequency ripple current 2.0 A at 120 Hz and high‑frequency ripple current 2.3 A at 50 kHz, supporting both LF and HF applications.
• Leakage and Dissipation: Specified leakage current 1210 µA (after 5 minutes at 20 °C) and dissipation factor measured at 20 °C, 120 Hz (tan δ for 50 V = 0.30 max).
• Temperature Range: Operating temperature −40 °C to +105 °C.
• Mounting & Package: Snap‑in terminal type in a radial can (φ25 × 30 mm); supplied in tray packing for production handling.
• Compliance & Availability: RoHS‑compliant and listed as mass production status in the LGU series.

Typical Applications

• General‑purpose power circuits: Provides bulk capacitance and energy storage where a 3.3 mF, 50 V electrolytic is required for general‑purpose designs.
• AC/DC and DC supply filtering: Supports ripple current handling at both 120 Hz and higher switching frequencies (50 kHz) as specified.
• Industrial and commercial equipment: Suited to designs that require stable performance across −40 °C to +105 °C and long endurance (3000 h at 105 °C).

Unique Advantages

• Proven high‑temperature endurance: 3000‑hour rating at 105 °C provides predictable long‑term behavior under elevated ambient and load conditions.
• Wide operating temperature span: −40 °C to +105 °C supports diverse environmental requirements without derating outside the specified range.
• Dual‑frequency ripple capability: Distinct low‑frequency (2.0 A at 120 Hz) and high‑frequency (2.3 A at 50 kHz) ripple specifications enable use with both line‑frequency and switching supplies.
• Snap‑in mechanical retention: Snap‑in terminal construction provides robust PCB mounting for radial can applications and efficient assembly with tray packing.
• Clear electrical limits: Specified leakage current (1210 µA) and tan δ measurement conditions (20 °C, 120 Hz) make it straightforward to validate designs to expected electrical performance.
• Regulatory alignment: RoHS compliance supports deployment in regulated regions and products.
