LGJ2D121MELZ15

The LGJ2D121MELZ15 is a snap-in terminal aluminum electrolytic capacitor from Nichicon’s LGJ series, designed for general-purpose electronic applications that require compact high-voltage bulk capacitance. It combines a 120 µF capacitance with a 200 V rating in a low-profile φ22 × 15 mm radial snap-in can.

This part delivers high ripple handling and elevated temperature endurance, making it suitable where robust smoothing, filtering and energy storage are needed within space-constrained power assemblies.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance, specified at 120 Hz, 20°C.
• High Temperature Rating — Rated for operation from −40°C to +105°C, with 2000 hours endurance at 105°C for long-term reliability under elevated-temperature conditions.
• Snap-In Radial Package — φ22 × 15 mm low-profile can with snap-in terminals for secure mounting in power assemblies; supplied in tray packing for production handling.
• Ripple Current Capability — 550 mA at low frequency (120 Hz) and 825 mA at high frequency (50 kHz), supporting demanding AC ripple and switching environments.
• Leakage and Loss — Specified leakage current of 460 µA and series loss characteristics consistent with the LGJ series (tan δ limits applied at measurement conditions).
• Manufacturing Status — Mass production availability for design continuity and sourcing consistency.

Typical Applications

• Power supply smoothing — Bulk decoupling and filtering in general-purpose power supplies where 200 V rating and compact height are required.
• Energy storage for power electronics — Local energy reservoir for circuits that need moderate bulk capacitance and high ripple handling in a snap-in form factor.
• Industrial electronic equipment — General-purpose use within assemblies that operate across −40°C to +105°C and require reliable long-term endurance.

Unique Advantages

• Compact, low-profile design — φ22 × 15 mm can minimizes vertical space while providing 120 µF of capacitance for constrained layouts.
• High ripple tolerance — 550 mA (120 Hz) and 825 mA (50 kHz) ripple ratings enable use with both line-frequency and high-frequency switching sources.
• Elevated temperature endurance — 2000 hours at 105°C supports longer service life in high-temperature operating environments.
• Clear electrical specification — Defined leakage current (460 µA) and ±20% capacitance tolerance allow predictable design behavior and margining.
• Production-ready supply — Tray packing and mass production status simplify procurement and assembly-level logistics.
• Proven series platform — Built on the Nichicon LGJ series specification set, including defined tan δ and impedance stability characteristics.
