LGU1E123MELZ

The LGU1E123MELZ is a snap‑in terminal aluminum electrolytic capacitor designed for general‑purpose power applications. It delivers 12 mF capacitance at a 25 V rating in a polarized radial can with snap‑in mounting, combining high bulk capacitance with a compact through‑hole package.

Engineered for elevated operating conditions, this capacitor is specified for –40°C to 105°C operation and is endurance‑rated to withstand 3000 hours of rated ripple current at 105°C. It is RoHS‑compliant (2011/65/EU, (EU)2015/863).

Key Features

• Capacitance & Voltage — 12 mF nominal capacitance with a 25 V rated voltage and ±20% tolerance, providing substantial energy storage for smoothing and bulk decoupling.
• High‑Temperature Endurance — Designed to meet endurance requirements after 3000 hours of rated ripple current at 105°C, supporting prolonged operation in hot environments.
• Ripple Current Performance — Rated ripple current of 2.69 A at 120 Hz and 3.094 A at 50 kHz, enabling effective handling of AC ripple in power circuits.
• Operating Temperature Range — Specified for operation from –40°C to 105°C, suitable for a wide range of ambient conditions.
• Package & Mounting — Radial, can style with snap‑in terminals for secure board retention and easy through‑hole assembly.
• Physical Dimensions — Body dimensions L: 4.5 × D: 2.2 cm with a seated maximum height of 1.772 inch, allowing straightforward mechanical integration.
• Environmental Compliance — Complies with RoHS directive (2011/65/EU, (EU)2015/863) for restricted substances.

Typical Applications

• Power supply bulk filtering — Provides bulk capacitance and smoothing for DC power rails where 12 mF at 25 V is required.
• Output smoothing for converters — Handles ripple currents typical in switching power supplies and converters, supported by specified ripple current ratings.
• Industrial and general‑purpose electronics — Suited for general‑purpose circuits that require polarized bulk capacitors with reliable high‑temperature endurance.

Unique Advantages

• Durable high‑temperature performance: Endurance rated for 3000 hours at 105°C under rated ripple current, reducing the need for frequent replacement in hot enclosures.
• Strong ripple handling: Explicit ripple current specifications at 120 Hz and 50 kHz (2.69 A and 3.094 A) make it easier to match capacitor selection to switching frequency requirements.
• Secure snap‑in mounting: Snap‑in terminals provide robust mechanical retention for through‑hole assemblies and simplify board handling.
• Clear physical profile: Provided dimensions (L: 4.5 × D: 2.2 cm; seated height 1.772 inch) help with mechanical planning and enclosure fitment.
• Regulatory compliance: RoHS conformity supports designs targeting restricted‑substance requirements.
