LGJ2E151MELB15

The LGJ2E151MELB15 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGJ series, offering a compact, low-profile φ30 × 15 mm can with snap-in mounting. Designed for general-purpose use, it delivers 150 µF capacitance at a 250 V rating with a ±20% tolerance and is built for elevated-temperature operation up to 105 °C.

Key performance attributes include defined low- and high-frequency ripple handling, controlled leakage and dissipation factor, and a 2000‑hour endurance at 105 °C—features that support reliable power-conditioning roles in a range of equipment where stable bulk capacitance and thermal durability are required.

Key Features

• Core Electrical 150 µF nominal capacitance at a 250 V rating with ±20% tolerance, providing predictable bulk energy storage for DC rail smoothing and decoupling in general-purpose circuits.
• High-Temperature Endurance Rated for operation from −40 °C to 105 °C with a specified 2000 hour lifetime at 105 °C, supporting sustained performance in elevated-temperature environments.
• Ripple Current Capability Low-frequency ripple current of 700 mA at 120 Hz and high-frequency capability of 1.05 A at 50 kHz, enabling handling of both mains-frequency and higher-frequency ripple components.
• Leakage and Dissipation Specified leakage current of 580 µA and a dissipation factor (tan δ) of 0.2 at 20 °C / 120 Hz, allowing predictable loss and stand-by current characteristics.
• Package & Mounting Snap-in terminal, radial can package in a compact φ30 × 15 mm form factor for secure board mounting and efficient use of vertical space.
• Durability & Stability Designed to meet LGJ series endurance and electrical stability criteria, including capacitance and tan δ limits after thermal aging and voltage treatment per the series specifications.

Typical Applications

• General-purpose power circuitry — Provides bulk capacitance for smoothing and energy storage where a 150 µF/250 V electrolytic is required.
• AC/DC and DC/DC power stages — Handles low-frequency and high-frequency ripple currents (700 mA at 120 Hz; 1.05 A at 50 kHz) for improved voltage stability across converters and supplies.
• Industrial and commercial equipment — Suitable for systems that require sustained operation up to 105 °C and predictable end-of-life behavior after 2000 hours at temperature.

Unique Advantages

• Compact low-profile design: φ30 × 15 mm snap-in can provides substantial capacitance in a space-efficient package for constrained layouts.
• Robust thermal performance: Rated operation to 105 °C with a 2000‑hour endurance rating supports long-term reliability in warm operating environments.
• Defined ripple handling: Explicit ripple current ratings at both low and high frequencies allow designers to size components with measurable thermal and ripple margins.
• Predictable leakage and loss: Specified leakage current (580 µA) and tan δ (0.2 at 120 Hz, 20 °C) enable accurate power loss and standby current budgeting.
• Secure snap-in mounting: Radial snap-in terminals simplify mechanical retention on PCBs and support high-density assembly where screw or clamp retention is used.
