LGU2F121MELY

The LGU2F121MELY is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGU series, rated at 315 V and 120 µF with ±20% tolerance. It is a general‑purpose, high‑voltage electrolytic designed for applications that require robust ripple handling and long endurance at elevated temperatures.

Key attributes include a –25°C to 105°C operating range, 3000 hours endurance at 105°C under rated ripple conditions, RoHS compliance, and compact φ20×30L radial can packaging with snap‑in terminals for secure PCB retention.

Key Features

• High Voltage Rating — 315 V rated voltage for general‑purpose high‑voltage circuits.
• Capacitance and Tolerance — 120 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Snap‑in Radial Can Package — Snap‑in terminal type in a radial, can‑style package sized φ20×30L (L: 3 × D: 2 cm) for reliable mechanical retention on PCBs.
• Temperature and Endurance — Operating range of –25°C to +105°C with a rated endurance of 3000 hours at 105°C when subjected to DC bias plus rated ripple current.
• Ripple Current Capability — Low‑frequency ripple current 750 mA at 120 Hz and high‑frequency ripple current 1.073 A at 50 kHz, enabling effective filtering across frequency ranges specified.
• Loss and Leakage Control — Specified tan δ of 0.15 and leakage current of approximately 580 µA, supporting stable performance after voltage application.
• Environmental Compliance — RoHS compliant, meeting directive requirements for restricted substances.

Typical Applications

• General‑purpose power supply filtering — Smoothing and decoupling in higher‑voltage power circuits where 315 V rating and significant ripple handling are required.
• DC bus smoothing and energy buffering — Bulk capacitance for energy storage and voltage stabilization in general‑purpose power electronics.
• High‑temperature environments — Applications requiring sustained operation at elevated temperature thanks to 3000 h endurance at 105°C under rated conditions.

Unique Advantages

• 315 V capability: Enables use in higher‑voltage designs without adding series components.
• Long endurance at elevated temperature: 3000 hours at 105°C under rated ripple ensures predictable life in demanding thermal conditions.
• Wide ripple frequency coverage: Defined ripple current specifications at both 120 Hz (750 mA) and 50 kHz (1.073 A) provide confidence for low‑ and high‑frequency filtering needs.
• Compact, secure mounting: Snap‑in radial can (φ20×30L) delivers a space‑efficient footprint with robust PCB retention for through‑hole assembly.
• Controlled electrical losses and leakage: tan δ of 0.15 and leakage current around 580 µA support stable operation after voltage application.
• RoHS compliant: Aligns with regulatory requirements for restricted substances.
