LGUW6151MELZ

The LGUW6151MELZ is a Nichicon LGU series snap-in terminal aluminum electrolytic capacitor rated at 150 µF and 420 V. Engineered as a 105°C standard device with snap-in mounting and tray packing, it targets general-purpose power applications that require high-voltage capacitance and extended endurance.

Key design strengths include a 3000-hour endurance at 105°C, RoHS compliance, and defined ripple current performance across low and high frequencies—providing verifiable stability for power electronics designs that need proven high-voltage capacitors.

Key Features

• Capacitance & Voltage — 150 µF capacitance at a 420 V rated voltage for high-voltage energy storage and filtering where a snap-in aluminum electrolytic is required.
• Endurance & Temperature — Rated lifetime of 3000 hours at 105°C and an operating temperature range of −25°C to +105°C, supporting sustained operation in elevated-temperature environments.
• Ripple Current Performance — Low-frequency ripple current of 880 mA (120 Hz) and high-frequency ripple current of 1.258 A (50 kHz) as specified for the part, enabling predictable thermal and electrical behavior under AC stress.
• Leakage & Dissipation Factor — Specified leakage current of 750 µA and tangent of loss angle measured at 20°C, 120 Hz; series data show tan δ max of 0.15 for 160–420 V ratings, supporting stable loss characteristics at rated conditions.
• Package & Mounting — Snap-in terminal, radial can package (φ22 × 40L / 22 mm × 40 mm) for secure board retention and compact installation in power assemblies.
• Regulatory — RoHS compliant (meets Directive 2011/65/EU and (EU)2015/863 requirements).
• Tolerance & Polarity — Polarized capacitor with ±20% capacitance tolerance at 20°C, 120 Hz for predictable design margins.

Typical Applications

• General Purpose — Suited for general-purpose circuits that require a 150 µF, 420 V snap-in electrolytic capacitor with specified ripple and endurance characteristics.
• High-Temperature Environments — Applicable where components must maintain performance up to 105°C for extended periods (3000 h rated life).
• RoHS-Compliant Designs — Ideal for projects requiring components compliant with RoHS directives.

Unique Advantages

• High-Voltage Capability: 420 V rating allows use in higher-voltage power circuits without upsizing to larger packages.
• Proven Endurance: 3000 hours at 105°C provides a quantifiable lifetime metric for thermal-stress planning and reliability forecasting.
• Defined Ripple Performance: Specified ripple currents at 120 Hz and 50 kHz give clear limits for thermal budgeting and decoupling design.
• Compact Snap-In Form Factor: φ22 × 40L radial can with snap-in terminals delivers secure PCB mounting while conserving board area.
• Controlled Loss Characteristics: Series tan δ limits (0.15 max for 160–420 V) and measured conditions (20°C, 120 Hz) support predictable ESR-related behavior in designs.
• RoHS Compliance: Meets RoHS requirements for environmental compliance across global product programs.
