LGY1E153MELB35

The LGY1E153MELB35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon’s LGY series designed for long‑life, high‑temperature operation. It is a polarized, radial can (snap‑in) capacitor rated at 25 V and 15 mF, optimized for industrial power applications where dependable performance and extended endurance are required.

Engineered to withstand extended ripple stress at elevated temperature, this capacitor targets industrial power supplies and ballast circuits that require robust smoothing, filtering and energy storage under continuous duty.

Key Features

• Capacitance & Voltage — 15 mF nominal capacitance with a rated voltage of 25 V and a tolerance of ±20% (–20% to +20%).
• High‑Temperature Long Life — Designed for continuous operation from –40°C to 105°C with a guaranteed lifetime of 5000 hours at 105°C under rated ripple conditions.
• Snap‑in Mounting — Snap‑in terminal, radial can package for secure mechanical mounting in power assemblies and chassis installations.
• Ripple Current Capability — Rated ripple current of 2.9 A at 120 Hz and 3.335 A at 50 kHz, with published frequency coefficients that increase ripple allowance up to 1.15 at 1 kHz and higher frequencies.
• Polarized Construction — Polarized electrolytic design intended for DC filtering and energy storage in power circuits.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863), supporting environmental and regulatory requirements.
• Compact Can Dimensions — Physical size L: 3.5 cm × D: 3 cm, with a maximum seated height of 1.378 inch for planning board and enclosure layouts.

Typical Applications

• Industrial Power Supplies — Bulk smoothing and ripple suppression where continuous high‑temperature operation and long life (5000 h at 105°C) are required.
• Ballast Circuits — Energy storage and filtering in ballast applications specified by the product series for this use.
• General Purpose Power Filtering — DC link smoothing and decoupling in equipment that needs polarized, high‑capacitance snap‑in capacitors with elevated ripple tolerance.

Unique Advantages

• Extended high‑temperature endurance: 5000 hours at 105°C under rated ripple ensures reliable performance in hot operating environments.
• High ripple handling across frequency: Specified ripple currents at 120 Hz and 50 kHz plus frequency coefficients (up to 1.15 at 1 kHz and above) provide predictable behavior across a wide frequency range.
• Secure snap‑in mounting: Snap‑in terminals and radial can package give robust mechanical retention for power assemblies and chassis installations.
• Clear electrical specification: 15 mF at 25 V with ±20% tolerance and defined leakage and tan δ limits enable straightforward design margins and verification.
• Regulatory compliance: RoHS compliant construction supports environmental requirements for shipped products.
