LGU2F221MELY

The LGU2F221MELY is a Nichicon LGU series aluminum electrolytic capacitor in a snap‑in terminal (radial can) package. It delivers 220 µF capacitance at a 315 V rating with ±20% tolerance and is designed for general-purpose applications that require high-voltage capacitance with sustained ripple handling and long endurance.

Key value comes from its combination of high-voltage capability, substantial low‑ and high‑frequency ripple current ratings, low leakage and loss (tan δ), and a 3000‑hour endurance specification at 105°C—providing predictable performance for demanding electronic assemblies.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 315 V with ±20% tolerance for high‑voltage circuits.
• Low and High Frequency Ripple Handling — Rated ripple current of 1.00 A at 120 Hz and 1.43 A at 50 kHz to support sustained AC stress in power circuits.
• Leakage and Loss — Specified leakage current of 780 µA and tan δ (DF) of 0.15 at 20°C, 120 Hz for controlled dissipation and low standby loss.
• Reliability / Endurance — Endurance rating of 3000 hours at 105°C (with DC bias plus rated ripple current), meeting the LGU series performance criteria.
• Operating Temperature — −25°C to +105°C operating range suitable for elevated ambient applications within the stated series limits.
• Mechanical & Mounting — φ20 × 50 mm can (approx. L: 5 × D: 2 cm) with snap‑in radial terminals; supplied in tray packing and listed as in mass production.
• Compliance — RoHS‑compliant construction.

Typical Applications

• General‑purpose power circuits — Provides bulk capacitance and ripple handling where a 315 V rated electrolytic is required for general‑purpose designs.
• High‑voltage smoothing and energy buffering — 220 µF at 315 V and specified ripple currents support smoothing tasks in electronic power sections.
• Elevated‑temperature environments — 3000‑hour endurance at 105°C makes the part suitable for applications that require sustained performance at higher operating temperatures.

Unique Advantages

• High‑voltage capability: 315 V rating enables use in higher DC bus and power applications where lower‑voltage capacitors are not suitable.
• Sustained ripple performance: Rated for 1.00 A (120 Hz) and 1.43 A (50 kHz), allowing reliable operation under continuous ripple stress.
• Predictable electrical loss: Tan δ of 0.15 at 20°C, 120 Hz provides a quantifiable dissipation characteristic for thermal and efficiency planning.
• Low leakage current: 780 µA specification supports designs where low standby loss and controlled leakage are required.
• Long endurance at high temperature: 3000 hours at 105°C with rated ripple current ensures longevity under elevated thermal and electrical stress.
• Serviceable mechanical format: Snap‑in radial can (φ20×50 mm) in tray packing for straightforward assembly and inventory handling.
