LAK2G101MELZ35ZB

The LAK2G101MELZ35ZB is an aluminum electrolytic capacitor in a radial can with snap‑in terminals, rated 100 µF at 400 V and designed for general-purpose electronic equipment. It is engineered for high-temperature endurance and abnormal-voltage resilience, making it suitable for systems exposed to voltage fluctuations.

Key performance characteristics include a wide rated-voltage offering (200 V, 400 V and 420 V options), endurance under rated ripple current for 2000 hours at 105°C, and safety measures to mitigate the effects of abnormally excessive voltage. The part is RoHS compliant.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with a rated voltage of 400 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• High‑temperature Endurance — Specified for operation from −25°C to +105°C and capable of withstanding 2000 hours of rated ripple current at 105°C with defined post‑test limits on capacitance, tan δ and leakage current.
• Ripple Current Performance — Rated ripple current of 550 mA at 120 Hz and 632.5 mA at 10 kHz to support high‑stress power circuits.
• Safety Features — Improved safety design for abnormally excessive voltage; pressure relief venting is specified to operate without creating dangerous conditions such as flames or dispersion of parts.
• Electrical Reliability — Leakage current specification follows I ≤ 3√(C·V) (µA) after 5 minutes at 20°C and tan δ ≤ 0.20 (120 Hz, 20°C), enabling predictable behavior in power applications.
• Package & Mounting — Radial, can-style body with snap‑in terminals for secure board mounting and robust mechanical retention in high‑vibration or industrial environments.
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High‑voltage power equipment — Bulk filtering and energy storage in systems that require 100 µF at 400 V.
